Corydalis Lutea and which other Corydalis?

18 years ago

Corydalis Lutea can make a nice show in the early spring here in the Atlanta area.

What other corydalis have you tried and does relatively OK here?

THANKSGGG

Corydalis cheilanthifolia(Fernleaf Corydalis) does extremely well for me. It will grow almost anywhere in the garden, sun, shade, moist, dry, in pots and in ground. It can become a nuisance if you care about things like that, as it seeds around profusely! Blooms in early Spring, like C. lutea and is evergreen here. Mine was started from a small container from a mail-order co many years ago, but if you can find fresh seed, I would recommend that avenue. Let me know if you can't find seed and I will save some in Spring for you or if you would prefer plants, I probably have a few around that I haven't weeded out.

Hi RB,
Thank-you. I'd not seen this particular plant before, and I LOVE LOVE LOVE it. What fantastically ferny texture. I don't have a problem with plants that like to happily seed - when they look this good, and display the properties you mention.
I'm on the lookout for seed, and may ask you for some when it's fresh!

THANKS!

corydalis/fumewort
Q

Corydalis lutea is an obsolete name for Pseudofumaria lutea, which is sometimes called Yellow Corydalis (Lutea means yellow), Rock Fumewort, or Yellow Rock Fumewort. Fumewort is a common name that, like most common names, can refer to many different types of plants. 'Canary Feathers' is a hybrid between Corydalis moorcroftiana (seed parent) and Corydalis wilsonii (pollen parent). So, 'Canary Feathers' is not a member of the Pseudofumaria lutea species. If you are still looking for a Pseudofumaria lutea (aka Corydalis lutea), check with Avant Gardens, Forestfarm, or Romence Gardens & Greenhouses for plants or J.L. Hudson Seedsman for seed.

I love the c. lutea, just watch out for corydalis incisa, or purple keman. I saw something like it in a nursery, but managed to keep my plant aquision disorder in check. Imagine my joy when I saw that the same plant, or something that looked like it, had volunteered just to the right of my greenhouse door! Karma ... the universe was rewarding me for exercising some self-discipline! The next year, it was growing vigorously and blooming all along that end of the small greenhouse. This year - in late March - it was growing and blooming all along that east end of the greenhouse and around the corner halfway down the south side. It had also hopped from the east side across the path to blanket the area around the compost pile and surround my potting bench, spreading around the corner of the rose bed, from whence it hopped across towards the vegetable garden which it was beginning to encircle. Time to do a little research: http://blogs.nybg.org/science-talk/2014/07/detecting-an-invasive-plant-before-its-too-late/ As difficult as it is to pull blooming things in March, especially these delicate flowers and leaves, I pulled out all that I could, enough to fill a 5-gallon bucket (compressed) and then some. What I couldn't pull, I cut to the ground so it wouldn't have a chance to set seed. I'll be keeping an eye out for more volunteers next year, and this year continue to battle the non-native terrestrial orchids - when one sees volunteers growing equally well in moist, humus-rich shade as well as crushed bluestone over nutritionally deficient native sand in full sun, one gets suspicious and looks it up.

Anyone grow corydalis 'Blue Panda' or another corydalis?

Thanks for the links, NHBabs. I think 'Blue Panda' is off the list. It was the first Corydalis I'd ever heard about, and the recent thread you mentioned was the first time I realized there were so many species! I like th fine leaf structure and think both the leaves and blue flowers would be a great shade addition, if blue is possible. It looks like I need to do more homework. And...that will have to come later, when the Winter Rest phase of gardening begins!

Corydalis lutea not blooming?
Q

I can only offer what I know about my yellow corydalis that have seeded everywhere from a couple of small clumps. They bloom heavily. I think yours may need more sun to bloom.. Everywhere they seeded & bloom are in bright but not baking hot sun most of the day. between rocks in stone walls and in a large crack in a raised bed. So their roots are between the cool rocks. Maybe that means they like lean soil, maybe that means they like a cool root run. I'm sure others can chime in. An additional benefit is that blooming corydalis are often self seeding. The seedlings love nooks and crannies. 90% of mine self seeded between rocks in stone walls and that one raised bed timber. I do not remember where I planted my original hand me downs. I know they did not thrive or self seed for a few years and I may have had to try more than once. Their roots, you may have noticed are very brittle so get as much soil as you can. Don't over fertilize them. They don't seem to need rich soil or very little soil come to think of it!. If you are going to bother to transplant them it might worth it to create an environment like the one I described. If you have stone walls plant one or two near those and maybe some seeds might find their way there. My impression is that they grow where they want to grow. They did not listen to my directions but did what they wanted to do, with abandon.

BTW, in addition to C. cheilanthifolia and C. lutea, I also grow Corydalis bulbosa(Synonym: C. solida), a pretty blue/purple flowered bulbous member. It is Spring blooming and then goes dormant until the following Spring and is very slow to increase in size. Have grown several other species and cultivars, but they were short lived, i.e., C. elata, flexuosa(Blue Panda, China Blue), ochroleuca, nobilis, flavula(a native annual with a very limited GA distribution) and an unknown blue-flowering species from the Himalaya's.
There are a number of native species, but most aren't available in the nursery trade, however, you may find a seed source if you want to try some of them.
