Live in St. Louis, MO- can plant take full sun

14 years ago

I'm debating if I want the new hydrangea or plant a knock out rose bush in an area that use to be shade but now the city cut down a tree and trimmed another so this area gets full sun. I would normally plant a KO rose bush but wondering about shade aspect wants limbs starts to grow back on trimmed tree. For now, would hydrangea take full sun?

Hyrangeas in general doesn't take full sun...there a few will do ok under full sun - such as Limelight, Pinky Winky or QuickFire...the usual mopheads - like Endless Summer, Nikko Blue etc will not take the St. Louis Full Sun in Summer...I used to live in Chesterfield, MO for many yrs, boy, it can get real hot there - over 95 for a week, 100 sometimes..under the same condition, a knockout rose will bloom like crazy...I have knockouts blooming like crazy with only 4 hrs of afternoon sun here in Jersey...imagine a 7 hrs hot sun in St. Louis, plus the humidity there, wow..the knockout would be in heaven...I dont't know what kind of tree they trim, it may take yrs to for the limbs to grow back, but then, if the spot on get morning sun, nothing else after mid-day, you could try one of those mophead Hyrangeas. I find it easier to get Endless Summer to bloom with some sun (2-3 hrs in the morning, nothing else) then the ones over the sunnier spot...the plants in the limited sun area never need afternoon waterings like the ones under the suunier spots...those in the sunnier spots wilt in summer afternoons and they look quite stress out everyday - and with fewer and smaller blooms. jmho.

If you want a hydrangea that likes the sun, get one of the paniculatas--such as Pinky Winky. On the other hand, an arborescens hydrangea like Annabelle can take some sun, but would definitely start wilting in all afternoon hot sun. It is the macrophylla hydrangeas, called mopheads, that need the most shade. So it depends on which type hydrangea you select.

In my zone 8, I grow all but the very light, chartreuse or gold foliage heucheras in full sun. IME, shade unnecessarily stunts their growth and washes out the color (purples more bronze than purple; golds/toffee colors less intense; heavily veined or marked forms lose their markings). But my zone 8 is pretty far north and sun intensity is much different than elsewhere in the country. I think in hotter climates, morning sun and afternoon shade (or lightly filtered/dappled shade) may be the best setting.

Wow another WS'er here in St. Louis. Granted you don't live here yet I think it is cool you where here for awhile anyway. So you didn't make it to the top of the Arch. Wow I had no idea that place could be so crowded on Memorial Day weekend. Everyone in my neighborhood tends to leave town so things were quiet here. Going to the top is worthwhile. It is a standard field trip for any school age kid living around here. Though I can't imagine it is anything compared to your John Hancock Center or Sear's Tower. I haven't been to the top of the Arch in years. One of my favorite visits was going up in the evening though it tends to be less crowded during the morning hours (before 10). So I've been to Chicago a few times and once to your gardens, which by the way I think are lovely. It just so happened when I was there they were doing a bulb sale. I brought home with me some gorgeous tulips. My home is about a 20 minute walk away from MBG. The climatron is so wonderful to escape to in the middle of winter. So the gift shop has seeds? I think I knew that yet I tend not to visit the gift shop of places that happen to be in my own backyard. This pass fall I took a stroll through there and gathered a tiny amount of seeds from plants they have an abundance of. Happy to say my joe pye weed and white snakeroot both germinated. -StLGirl

Wintering in sunroom/summer outside in St. Louis? Can I do this?
Q

Hi Betty Lu, 1. I think they'll be fine as long as they don't freeze. Above 50 is better, and you can put in a small heater if it dips down. Some species are more sensitive to cold, like most aechmeas. Neos are more tolerant of cold. 2. Not necessarily. If a plant puts out nice pups which grow out, then I separate them when they are 1/2 to 2/3 size of the parent, and I will repot the pups in a single pot. As they get bigger, you can of course put them individually in larger pots. I keep the parent plant if it's still alive to make more pups. 3. They are constantly growing, and will flower at different times depending on the species. 4. I keep mine in part shade/bright shade in the warm months. Morning sun is good because it doesn't burn like the afternoon sun. They can make nice groupings under trees or large bushes where there is filtered light. Maybe you can put them out when night temps are above 55F? I'm in N. California and bring the prized plants indoors for the coldest months. Some stay outside under the eaves where it is going to capture some warmth emitting from the house. While they may not be hit by an overhead frost, they are still vulnerable if a persistent freeze comes a long.

Intersectional or Itoh peony - can it take full sun?
Q
Comments (7)
Thanks! I actually took a short trip to Ferncliff Gardens today (http://www.ferncliffgardens.com), to view their huge peony display gardens. I saw their intersectionals growing in full sun, including Garden Treasure, which I agree is a beauty to behold in person and is selling for $200. I also talked to the owners, who confirmed that they do great in full sun. I was also considering getting a "coral" (Coral Charm in particular), but the gardeners on this forum were absolutely correct when they said the corals fade too quickly. They were not as impressive as I expected. Even the regular pinks looked better. And I saw the most gorgeous reds in my entire life, in "Red Charm" and "Orlando Roberts". Pictures on the Internet do not do these red peonies justice. "Henry Bockstoce" came in a close second for color, but the blooms are so huge that the stalks do flop on the ground. "Red Charm" was slightly smaller with a beautifully shaped center, and had stronger stalks - no flopping. "Orlando Roberts" was the deepest most striking red, like a black red you could see from a great distance away, but it had the smallest flowers of the three. Top 3 peonies I've decided on so far -- Red Charm, Bess Bockstoce, and Garden Treasure. Deborah Here is a link that might be useful: Orlando Roberts peony

Hi Vt - I used to live in St Louis eons ago - our summer sun & humidity in IA make quite a statement as well!!!

I agree w/ O & Db - if you like the mop-head type of blossoms your choice might be quite limited, however, new cultivars like *Tickled Pink* & *Vanilla Strawberry* ... worth looking into! No doubt *KO Rose* bushes will have a ball & can grow huge, as well (I've had to severely prune last season to tame down the ones in F/S).

I happen to be partial to 'loose & lacey' (sounds awful for lovely dames, huh!!! LOL) Paniculata blossoms - will have a ball under F/S exposure as well & offers Winter interests (if you won't mind the *dirty socks* color by then) ... "gamboling" in the Winter winds! Â;)

Good luck on your final choice ... winners either way!!!

Have you considered the smaller buddleias such as little ball? They would do well in full sun and give you blooms too.

I have KO's in my backyard that get full sun and bloom like crazy. I love those roses, they have little maintenance besides getting rose food every couple of months. I however do not have room fro a kO in this area I wanted to place hydrangea. I was looking for a small hydrangea that can take getting some sun

Hi again- I'm not an expert & my limited experience since 2006 ... mopheads might scorch under full sun. Paniculatas might be your best bet ... they are mostly huge (6'x6'-10') The new 2010 intro, promoted as more compact ... *Van. Strawberry* (6-7'hx4-5'w) & *Tickled Pink* (4-5'hx5-6'w) ... I just got one of each & jury is still out! VS was developed in UK & TP by Dr Dirr in GA (I have another of Dr Dirr's H & is one of my most beautiful H serrata. I suggest u do a search on compact f/s cultivar, if u are bent on Hyd'g for the site you have in mind ... will help in your choice!

The up side, if you can afford TIME & an alternate site ... u can always dig up & relocate!

'Hope this helps ... my best to u!!! Â;)

I live in Chicago area and planted a ES this spring in a almost full sun location (get sun all morning - 4 pm). We are having a hot spell (~85-90f) the last 3 days. The plant really wilt during the day. It mostly came back in the evening. But some of leaves already became dark and crisp. I lived in STL a few years ago and the summer there is long and hot. So I would not recommend this type of hydrageas in a full sun or mostly fun sun location. JMHO.
