Coast Redwoods and Giant Sequoias in the Southeast
Comments (55)" There is also a very large, and interesting plantation of them in Maui, not the southeast, but still a really warm humid climate" Nope! Wrong again! The redwoods there are mostly planted above 5000', a climate where dewpoints are always << 60F, thus nights are going to be in the 50s at worse, and even 30s and 40s in winter. Highs probably never hit 80f, even during the worst heatwaves. Not at all a "really warm humid climate". A few are a bit lower, down to 3000', but their growth seems to become abnormal. Even there, summer are as cool or cooler than Boston's!...See MoreSpring Pictorial for Lizalily - Part 2
Comments (30)Thank you, Chaz! I'd love some Lupine seeds! We grew them at the garden center I worked at years ago... a few would bloom the first year, the majority the second... they were started in a large greenhouse, so I think that might account for the first year flowers... but every time I planted them in my garden, they would flower very sparsely and die out by the second year. They were planted on the south side of a patio fence enclosure, so I thought they were fairly well protected... although I'm sure the northern winters are what killed them. When I trucked cross country with my ex many years ago, I saw loads of beautiful native Lupines growing along the highways in Colorado! What a sight that was! I've always wanted to include them in my cottage style borders, but they just never did well for me. That was in zone 4b, so maybe they'll have a better chance of survival here in zone 5b. Thanks, HoustonPat! I love spring blooming bulbs, tulips being one of my favorites! We have plans to add more Parrot Tulips and Species Tulips this fall, so next spring the gardens should be even more gorgeous! Those raised beds began life as backdrops for archery targets... they were heavily screened on both sides and have rope handles for ease of moving, as you can see in the photo... I've removed the screening from one side to open them up, laid them flat, and they make excellent raised beds! There are about a dozen total of these screened frames, and we've commandeered all of them for use as raised beds, since they weren't in use as target backdrops... several are veggie and herb beds, and the remainder will be used to grow on perennial seedlings for sale purposes... we're starting a small driveway flower business to help offset the cost of gardening and plant purchases! Gardening can be an expensive hobby! Kitty, those blooms are gorgeous! I especially like the Mont Blanc! I'm really glad the majority of your older bulbs survived and came back to flower for you! We don't have any Tree Peonies yet, but I do plan to petition for some to be planted next year! The catalog photos are always so beautiful! I wasn't even aware they grew in such northern zones! I never looked into them before because trees and shrubs aren't really my specialty in gardening, but now that I have more space to garden in, I've become a lot more aware of the larger things that make up the "bones" of good landscaping and gardening! I'd love to see photos of yours!...See MoreWhy so few coast redwoods?
Comments (19)The amount of misinformation on gardenweb boards over the years is very annoying to me. So many people talking out of their a--. It is a rare case that someone is authentically, forgivably mistaken. As pineresin is when he states no large S. semprevirens are found outside zn 8 & 9. "z8 is a tad marginal for Coast Redwoods" LMAO! In fact, there are two 90' coast redwoods in zn 7b Williamsburg, VA, and has been since around 1955 when they were planted. I personally saw that tree after 0F in 1994 and it was uninjured. Lightning, hurricanes, and inept college landscaping crews are the greatest threat to those trees now, if 1979 and 1985 could not kill them off. One was seriously damaged by Katrina. Furthermore, one of the best informed horticulturalists in the Washington, DC, area, discovered a large old CR tree in a 7a suburb of DC. He has a Pineresin level knowledge and there is absolutely no chance he was mistaken. I think he said it was around 40' but I could be mistaken. Such a tree would have survived well below 0F as recently as 1994. He tried to get Hines to micropropagate it as a hardy coast redwood but could not get them interested. (he is personal friends with higher-ups at Hines, and has introduced other plants through them) People don't seem to understand/appreciate that in the last several hundred thousand years the Earth's climate has experienced a great deal of variability and that most plants have resistance to conditions well beyond those in their current native ranges. Pictures have been posted of the test Wollemias in DC, after around 7-9F (sorry Pineresin you will have to translate) and some were almost uninjured appearing. That is probably 10F colder than the minimum in the current location where W.n. was found. I grew for many years a Fuchsia regia from the Orgon mountains of Brazil, a 9b roughly like the climate of J'burg, ZA, yet this plant tolerated 0F with ground frozen solid 6 inches deep. Such conditions would not have occurred in its native range for at least several thousand years, probably. Not all plants retained the genes that either purposefully or surreptitiously permit such survival of course....See More3 years of Sequoia sempervirens, the species.
Comments (22)I'm a bit confused, that's your Sequoia? Wow! I'm amazed it recovered! My Sequoia 'Soquel' has only seen 11F/-11.6C so far, but was completely undamaged by that. Mike Dirr for some reasons lists that cultivar as zn 6 hardy. A famous PNW plantsman's response to that was: "No, that's not possible. He's been outside of Georgia, what, 5 times in his life?" LOL. But, I thought it was a good one to try in my garden, along with 'Swarthmore Hardy'- whose origins are somewhat mysterious, as Andrew Bunting denied introducing it, and he's the only one who should really be able to sign off on that name. The oldest Sequoia north of Williamsburg, VA is actually at the Barnes foundation. The next time I'm in the DC area I'm going to try to find a 50 footer that is allegedly somewhere in Silver Spring, MD. As I've posted before, I will grant the east coast Sequoia skeptics this: no plant predates the 1930s, as the William and Mary trees were planted in the 1950s, and none of the 5 or 6 trees planted at various Philadelphia area arboreta in the early part of the 20th century seem to have lasted 100 years. What I wonder though, is if the current clones at Barnes and Swarthmore are related, or were clones of the one tree that is known to have survived the 1930s until at least the 40s. Not sure what killed the other 4, the 1930s had it all: heat, drought, and massive cold outbreaks....See Morefamartin
