magnolia in northern CO? ! ?

skeating
19 years ago

I was walking today and saw a beautiful shrub unlike any I have seen. It's in full bloom but doesn't have any leaves out yet. The petals are pure white and narrow, and the blooms had a very spicy exotic fragrance. At first I thought it was a tree peony but I think it is a magnolia.

Anyone out there growing magnolias in z4? I didn't think they would take here. The shrub is living in a poorly maintained garden so I don't think it's being coddled. Could I have mis-identified this plant? I found a photo on the web at this URL that resembles the bloom. Very elegant and architectural shrub.

    Certainly not a Magnolia but perhaps Amelanchier alnifolia or Amelanchier pumilla. Fragrant, an early spring flowering shrub/tree

    Rosa, I am familiar with the A. alnifolia which is native here. It is similar to the plant I saw today but a couple of things make me think it's not the Amelanchier. This plant has a single flower at the end of the branch, sort of prominently displayed. And the flowers are large- about 3 inches in diameter, with lots of petals. It could be a variety of Amelanchier but I don't know. We are expecting either rain or snow tomorrow. If it's rain I'll try to get a photo and post it, but if it's snow I am probably out of luck til next year.

    They grow together in my neighboring woods. With my own collection of plants,I often crowd shrubs together, making it impossible for each to achieve it's finest symetrical look, but giving a natural, woodland edge appearance.

    Thanks for sharing your experience! That is good to know. I would actually prefer if it grows slowing and stays on the small side because there's an a semi-dwarf apple tree just west of where it would go and I don't want it to complete with that. We're tall, but our yard is fairly deep, so even if it doesn't get very tall it should at least help (along with some other plantings) make it feel a little more intimate and less like we're on display to the neighbors in behind us. Right now we just have a concrete pad and then the lawn starts, so it doesn't feel very tranquil on the patio... seems like something is missing. We do have a trellis on the side of the patio so we already have some privacy from the neighbors to the side of us. Some of the magnolias at the HD were already kind of tall (maybe 5-6 feet or so) but they were a tad pricey ($90) so I was leaning toward a smaller one. If yours does well in the cold winter temps of Michigan, then I think the buds should do fine here. I suppose the blooms could still go quickly if we have hot temps in the spring, which is not uncommon here, but it's probably worth a try. Thanks again!

    My one has survived 4 winters. It just doesn't grow much. Grew about 6" the first year but the last two I haven't seen any at all. I'm thinking it's not getting enough nutrients because of my extreme alkaline soil despite using acid fertilizer. I'm thinking of stepping up the amount of fertilizer. Maybe using a liquid type so it's fast access. Here's hoping that helps.

    If the soil there is alkaline as it is around here, I doubt you'd find a magnolia tree looking healthy in a poorly maintained garden, unless it had yellow leaves.

    Magnolias like acidic soils and get chlorotic pretty easily.

    Hey there. I'm up in cheyenne, and while I was wandering around lowes, I saw a magnolia tree for sale... it had blooms on it! I was going to go back after the snow today and see how it looked - I love magnolias. :) Now I know that lowes probably didn't get it from a local nursery, but chances are if they sell it, it'll grow, right? Just thought i'd pitch in.

    P.S. If any of you are up my way, and know of an awesome local nursery, i'd love to hear it!

    Nope- I'm in Berthoud but moved recently from Fort Collins where we have several good nurseries I think. But I rarely venture north of the border (no implication so don't take offense).

  • bpgreen

    I don't know that I'd assume that if they sel it, it will grow here. Especially when the they is a "big box" store.

    I bought my magnolia from a nursery, and, although magnolias will grow here, I should have checked the ph of my soil first. My soil ha a ph over 8, and magnolias like acidic conditions. It looked fine the first year, but by the second year, when it was using the soil in my yard instead of the soil in the pot it came in, the leaves started to turn yellow. At first, I thought maybe magnolias have yellow leaves, but I checked up on it and found out that it was suffering from iron chlorosis. As time went on, despite everything I tried to do to lower the ph, the leaves got yellower and yellower, until they started turning brown and falling off. In the end, the tree died.

    The abeliophyllum is beautiful! But no yellow stamens, more petals, and the flowers on this thing are not pendant, they face upward. The plot thickens...

    I would love to grow a magnolia or two here. It seems that there is some success with them even if in alkaline soil, with careful and deep ammendment of the soil where you plant them.

    I wish we could add more than one link here but here is one about growing magnolias in Utah, and below that is a link about growing magnolias in Canada; part two talks about alkaline soils. [url]http://extension.usu.edu/files/gardpubs/magnolia.htm[/url]

    Interesting site and I will have to read it through when I'm done making my soup. On page 4, the Leonard Messel is similar to the flower I saw, petals slightly more slender at the base and more of them (petals? stamens?) only smaller and all white, recurved in the center. Arrgggghhh... this is as bad as trying to remember someone's name who you went to high school with!

  • bpgreen

    Thanks for the links, Holly.

    Just the other day, my wife asked me if I thought there's any way we could get a magnolia to grow in our yard.

    Now, all I have to do is "find a protected area where the soil drains" or maybe create one.

    It sounds as if I can get around the problems with the alkaline soil if I add enough organic matter, and part of the trick, I'm sure, is to do it in advance.

    One question, though. The USU extension site says that magnolias do best with deep infrequent watering, but the Canadian Gardening site says they all have shallow root systems. These seem to be contradictory. If they have shallow root systems, how do they do best with deep infrequent watering?

  • oakiris
    19 years ago

    This is somewhat contradictory, isn't it? I have read on several sites that the magnolias are shallow rooted, and yet a lot of sites also recommend deep watering. I think basically you just don't want the roots to dry out so the deep watering just ensures that the entire root ball gets moisture.

    Also, (you may already be aware of this) I read that the water-soluble acid fertilizers, such as Mir-Acid, I assume, are not recommended. Solid acid fertilizers such as slow release evergreen fetilizer spikes or cottonmeal are apparently the way to go. I personnally would also mulch with pine bark mulch to help lower the PH in our very alkaline soils.

    Please let us know if you decide to grow one of these beautiful trees - info as to which cultivar you buy and where purchased would also be helpful for those of us that are "want-a-be" magnolia growers! :-)

  • bpgreen

    I did not realize that the water soluble fertilizers are not recommended. Yet another thing I did to contribute to the demise of Magnolia I.

    Since I called it Magnolia I, I guess you can surmise that there will be a Magnolia II. But this time, I know what to expect, so I'll make a more educated attempt.

    I'll probably buy it at a local nursery.

  • oakiris
    19 years ago

    If you find one at a local nursery the folks there should be able to help you with care instructions for your area, too, which is a plus. I've never seen any magnolias at the local nurseries that I frequent, but I think I'll take another look.

    OakIris, now that I've taken the time to read it through, the link you sent was very informative. I revisited the mystery shrub and I am confident it is a magnolia- probably the "Royal Star" or a similar variety. www.monrovia.com has a photo that closely resembles the blossom of the shrub I was trying to describe- gotta be it. And read this description from the Canadian magnolias link you sent: "The flowers of the saucer magnolia... average nine petals and are much wider and largerÂup to 25 centimetres acrossÂthan those of the star magnolia; inner petals overlap and form an almost closed chalice, while outer petals spread slightly to make a saucer." Sighhhh...

    Way cool skeating. I am absoulutely stunned that this has survived with the neglect especially in this climate.

  • oakiris
    19 years ago

    Good to know that you were able to identify the tree, skeating. Who ever planted it originally must have prepared the soil correctly and taken care of it until the folks that now own the property moved in and began neglecting everything. (This is one of my sorrows about being a gardener, knowing that the garden I have created and grown and cared for with love and delight will likely disappear after I am gone - I can just imagine the new property owners tearing everything out and replacing it all with sod and junipers!)

    I have just the place for a small magnolia in my back yard -you've inspired me to look for one now, skeating. The 'Royal Star' cultivar might be just the one, as it is obviously hardy enough to survive no matter what!

    Holly

    Here is a link that might be useful: Magnolia 'Royal Star'

    On second thought, since the 'Royal Star' seems to need a milder climate than ours, maybe I'll go for this cultivar instead!

    I stopped at Echter's yesterday to check their magnolias. None of them looked very good and they didn't have 'Jane.' I will wait until Paulino Gardens gets their shipment to see what they have, but I have a feeling if I want a particular cultivar I will have to order it on line.

    I had a Royal Star for several years and it did quite well. It was in a wind protected area (southeast of the house with a large juniper on the west)and no amenities were added to the soil, a fairly heavy clay. Unfortunately, some cattle got out and managed to stomp it into the ground, along with a lot of other plants. Sigh. Decided to redesign the garden and never did replace it.

  • bindersbee

    Yes, magnolias will grow in Utah and Colorado. Not the 80 foot tall, fabulous ones though. There are two main ones that will work. First, the Saucer Magnolia (Magnolia x soulangiana) can get up to about 30 feet tall and has 8 inch purplish fragrant blooms. There are several of these growing at the Utah State University Campus in Logan (definite zone 4). They have been there for many years (by the chemistry building near Old Main) and are somewhat sheltered in their location on the south side of the building.

    Secondly, the Star Magnolia (which is probably what you saw) will grow here. I've seen many around the Salt Lake City, Utah area. This is a shrub.

    Defying all sense of logic- there is a beautiful Southern Magnolia growing fabulously in the yard of my parent's neighbors in Sandy, Utah (yep- alkaline soil but nearly all sand). I can't explain why it is doing so well as it is the evergreen type of magnolia. I do know it has a south exposure and is protected on the west by a very large Colorado Blue Spruce. I've been told the spruce helps acidify the soil but I don't know. Also, the yard is on a hill so between the sand and the slope, water would drain away really well. No one believes me that this tree exists so I guess I'll have to take a photo. All the ones that grow okay in alkaline soil have deciduous leaves but this one has evergreen ones. So, if you have PERFECT conditions, you could possibly grow even a Southern Magnolia in the Intermountain West.

  • achang89
    18 years ago

    If the original photo is correct, this is the Star Magnolia, Magnolia stellata. Royal Star is one of them.

    Most of the deciduous magnolias are hardy in Z6 and some are hardi in Z5.

    Also, some of the southern magnolia are hardy to Z6. I can think about M. grandiflora "Victoria" and M. granfiflora "Claudia Wannamaker" Both are evergreen and hardy to Z6. You can also try M. virginiana, the sweetbay magnolia. It is semi-evergreen though in cold climate.

    Hi - here's my two cents. I lived in Denver and grew a star magnolia there and it did quite well in a protected southwest facing area. I had seen one growing in my neighborhood (it was about 8-10 ft tall and bloomed profusely against a south facing white wall). There are also two specimens growing on the DU campus on the west side of the building that houses hte bookstore.

    In addition, there is a saucer magnolia growing in front of a house on University Blvd a few blocks north of I25 in a front yard on the east side of the street. It is huge! with beautiful pink flowers and dark green, glossy leaves. I almost caused a car wreck the first time I saw it. I grew up back east in Md where there are lots of them and this was the first one I'd seen in Denver. Check it out this spring, if you gt a chance.

    Now I live in Steamboat - zone 3/4 - and have lots of adjusting to do!

  • oakiris

    I never did get a magnolia. I decided that I shouldn't plant a tree that, from what I have read, is clearly not happy in alkaline, clay soil. But then I revisited this thread and read juliaz5denver's post...I will definitely look for the mentioned University Blvd tree this spring. Perhaps it will inspire me to try one after all....! :-)

    (Tomorrow is the first day of spring; we are supposed to get up to 14 inches of snow tonight, but I haven't seen anything yet.)

    I love magnolias and living in zone 4a they can be a bit challenging. I would look for one called Merrill (see link below). It has proven the most reliable here withstanding cold, windy winters. It is probably the most commonly one planted in Minneapolis. I think this magnolia is tougher than magnolias are given credit for. There is one in my neighborhood growing in a parking lot in about a 10ft diameter circle. This doesn't seem like your ideal growing spot for a magnolia, but it is about 15ft tall and blooms beautifully every year. It also has a huge grocery store parking lot to the north so it wouldn't be considered a sheltered spot either. I also do yard work for a woman that has one (about 10 years old) and she never does anything to it (water etc.) and it blooms every year. However, your CO summers might be drier than ours, not quite sure about that one.

    Anyway, check out the link below about one MN nursery's experience with magnolias in zone 4.

    Hi,

    Is Sweetbay Magnolia (Magnolia virginiana var. virginiana) self-fertile? Does anyone have just one specimen growing in a region where there are none nearby and yet still get fruit?

    Thanks,
    Steven

  • erikamccaig
    15 years ago

    Yes, the sweetbay is self-fertile. Mine is probably the only one for 60 miles, and gets flowers and fruit. Trying to sprout a seed, however, would be a tedious thing. We live in Colorado Springs, but way up on top of Cheyenne Mountain.
    I got a Magnolia Virginiana "Moonglow" sweetbay from Forestfarm.com a few years back and it seems to love living in Colorado. It is one zone hardier than the regular sweetbay, and after only 2 years, it over 15 ft. tall and doing great, Right now it looks burned because it has evergreen leaves which get burned edges, but you get new leaves in Spring and lemony-scented flowers sporadically all summer long. Well worth finding a protected spot where you can enjoy the perfume. Ours is by the hot-tub.
    The nursery in Canyon City sells tons of Bracken's Brown Magnolia, which I think is pushing it for Colorado.
    The biggest trick here is to find a location with protection from those God-awful NW winter winds, and water slightly more deeply and often than the "easy" trees. But it can be done.

    I live in the bottom of Cache Valley (where the coldest air flows to in winter) near Logan, in extreme northern Utah. I have experienced -45 before at my home. -30 is not unusual. -20 to -30 is common in winter. I'd had success with several magnolias. I've tried about 20 different named varieties, but the most successful so far have been Sweetbay 'Moonglow' (surprisingly hardy), 'Jane', 'Royal Star', 'Marilyn', 'Toro', 'Leonard Messel' and a couple others I've forgotten the names of. I've planted "Merrill" several times but it keeps dying out. We had a freak cold snap in November 2010 after a very warm October (-20 on Thanksgiving morning), and I lost all of my peach trees and cherry trees (but one) due to late dormancy, but all of the above magnolia trees survived. I had die back to the trunk on all but 'Moonglow', 'Toro' and 'Jane' Another promising one is "Ballerina". Good luck! Don't give up in zone 4. Just keep replacing the ones that die out until something sticks! You might try other fun plants to go with your magnolias like Blue Moon wisteria (zone 3) and Fargesia bamboo.

    People generalize the northern Utah climate too much. There are so many differences in the growing season and temps between Logan and Salt Lake City. Ogden to Salt Lake is a full 3 hardiness zones warmer. That makes a huge difference in what can be grown here with a little winter help.

    Hi Mark. That's for sure! I have an update. I now have a beautiful large magnolia tree that is now about 15' tall and spreading, with HUGE reddish blooms. Larger than any other blossoms I have ever seen. This last Spring it was covered in blossoms! The variety? Red Baron. It is awesome! And perfectly hardy. I'll upload some pics in a day or two.

    I have a Royal Star Magnolia that I fell in love with at Home Depot and brought home about 10 years ago. Had I done my research I probably would not have purchased it, but I was fairly new to gardening in CO at that time. I ended up moving it to a new (more protected) location after a few years, even though I read that they don't like being moved. Moving it seemed like a better alternative to leaving it in the exposed area where it wasn't thriving though, and it has done better in its current location where it gets wind protection, morning sun, and a later afternoon sun in the summer. It does suffer from some chlorosis and rarely has a lot of blooms in the spring, but it's still a beautiful tree and I don't regret purchasing it.

    Over the years I've seen plenty of stores (especially the big box ones) sell a lot of trees that don't do well in our climate. There's obviously a market for them. Having grown up back east with a front yard full of dogwood trees, I've come pretty close to purchasing one here when I've seen them for sale in the spring, but have resisted the temptation because I know better.

    When I was at W.S.U. in Pullman, WA (Palouse Hills wheat country, with the natural vegetation being bunch-grass steppe except in ravines or on hilltops where there is enough additional moisture for trees and shrubs) one of the buildings enclosed an outdoor decorative pool with an island in the center. Occupying this island was a Cornus florida of some size. I figured the humidity from the water and whatever shelter the building walls might have been providing made it possible for it to grow in that spot.
