Splendide in full sun

rouge21_gw(5)August 3, 2013

I have a Thalictrum "Splendide" which I think does well in a somewhat shady location but after seeing GW member twrosz "Splendide" planted in full sun (see link) I was bowled over as it is a spectacular specimen, I almost immediately went out and quickly planted another one in August 2012, in also a full sun location. So 2013 is its first full year in this situation. Of course it isn't nearly as awesome as twrosz's but it has done just fine with much more sun and I am hopeful it will become fuller and more floriferous in subsequent years.

Here are two shots of this plant in our garden.

Here is a link that might be useful: twrosz's incredible

Wow!
Is it really that purple? And in full sun?

Gotta get me one of these. It would look wonderful in front of our long fence :)

I don't have that variety and the one I have is in shade - and doesn't do well. All the best-looking ones I've seen are in sunny locations! I really need to remember to move mine too...

Rouge,
Love that Thalictrum "Splendide" and your garden combination. Now I need to find one. I have not seen them here in our local nurseries. Is there an online place people would recommend?

Those hydrangeas are lovely too. Are they hydrangea Bobo?

Thanks
Vivian

Good pickup Vivian as they are "Bobo" (3 of them).

Now full sun for myself and twrosz may not be nearly as intense as those of you in zone 6 and beyond. All I can say is that in my full sun location it has done very well and I haven't seen much wilting during hot dry spells. I am always surprised at how long these delicate flowers last.

Molie, they are not purple (must be my poor photography skills). I would consider them pink. Here is a close-up of these same blossoms.

Thanks, rouge21, for the head's up --- I have full, intense all-day-long sun in the back yard AND those are beautiful even though they're more pink than purple. In any case, don't blame your photography skills. Sometimes it's just the camera you use or even the kind of sun when the photos are taken.

I still think those would look wonderful in the back yard along our gray fence. Splendide certainly creates an elegant bouquet!

That is stunning! Love the frothy color. I wonder how it would do in my dry heat.

Cheryl, given your more intense sun you might consider planting one in a part sun location?

Rouge, yes that would be a good idea. We don't have a lot of shade (very few trees), but I could try it next to a wall. Your Splendide makes such a dramatic statement. I used to grow Boltonia Snowbank for the same effect, and it was nowhere as big.

Thanks SB. But it is twrosz that showed me the way as I didn't realize Thalictrum could be so successful with lots of sun.

Anyone with Splendide Album? Is it smaller or the same size? Is it supposed to be pristine white or very pale violet?

That is most definitely a magnificent plant!

My Thalictrum rochebruneanum is a bit similar in growth habit and flowers, but not quite as dense as yours. For the first few years I grew in in partial shade, but then tried it in full sun and WOW - what a difference that made. Maybe it has something to do with what part of the country or world you live in? Farther North more sun, farther South less?

I've also found these to be pretty intolerant of dry soil for extended periods of time. How about yours? In last years drought, mine really suffered. In fact, all the foliage disappeared by mid summer. It did come back this year however.

I do not have "Album" 'wieslaw'. Taking inventory I have "Splendide", aquilegiifolium "Sparkler", "Evening Star" and I think the last one is "Hewett's Double". This is a great genus.

'wieslaw' what Thalictrum do you have in your garden?

Rouge, at the moment I have 2 Splendide, 2 flavum glaucum , 2 delawayi album(of which one rebounds after being eaten to the ground by a chicken), T. polygamum and a delawayi Ankum.

I have had several which failed here and several I got rid of

Fails:
Perfume Star- Survived the first winter to die in the summer (probable cause of death- too dry)
T.reniforme-as above
T. delawayi Hewitt's Double- tried twice, never survived the first winter

Got rid of:
T. Elin- the foliage was nice , the plant robust and erect, but the flowers were not showy at all here
T. aquilegifolium: too floppy, aphids and mildew magnet.
T. aquilegifolium Thoundercloud: from tissue culture, did not fit to the description, only half the height(dwarf), and not particularly heavy bloomer.
T. Black Stockings: from tissue culture, the stockings were green not black, and the plant very floppy

I'm willing to try T.aquilegifolium again if I find a clone more fluffy than I had.

I've had one for four years and the other in it's second year in about eight hrs of sunlight, both doing fine. The only problem, if not staked, that might occur is that a sudden wind gust might break some stems due to the extensive top spread.

Yes for sure this plant needs staking. I generally try not to choose plants that need permanent support but I make an exception for "Splendide". I personally put a couple of stakes early in the season, well before it needs it. I may well keep these 8 foot stakes in the ground for good (although now I recall that snow gets piled near there).

Kevin, for sure they are not drought tolerant but I have other plants that are more water needy than "Splendide". This season with all the rain we have had I haven't had to give it much supplemental water.

Beautiful plant!
I don't think I've ever seen it for sale or in a garden around here.

So true franelli.

I posted the updated picture to show people that this plant is is a 'work horse' with respect to the length of bloom...easily 5 weeks.

As well it is very hardy + it takes up very little horizontal space nearer the ground and so most gardeners could find a place for it.

That is amazing, Rouge21! I guess the stake is what is holding it up with all that ice on it. It's very pretty. I'm imagining a whole bed of those on either side of a walkway covered with ice. It would look like a real fantasy landscape. :-) You also did a great job with that stake because you could hardly notice it when it was in bloom and if it weren't taller than the plant now, you might think it was part of the plant.
