Gardeners' Notes:


On Jan 26, 2014, coriaceous from ROSLINDALE, MA wrote:

I like this plant for many of the reasons that have been mentioned: its lacy foliage and its constant bloom from June till hard frost, and its shade tolerance. It emerges from dormancy in very early spring, and does not share space well with early spring bulbs.

Blooms in deeper shade than any other hardy plant I know (except its close relation Corydalis ochroleuca, which is very similar except for flower color.) Best in partial shade with well drained soil and consistent moisture. It hates hot summers, and flowering may pause for a couple of weeks when we get a heat wave.

I find that newly planted nursery plants often look good for a month or two, then die. But if I'm patient, I'll find new seedlings around a few months later. These become longer-lived plants... read more

This grows in my zone 4 garden. Got it from a friend and finally found out its name. Survives in sun but likes part shade. I've also found it pops up in strange places. I have not had a problem transplanting it- I even put it in pots and its looks nice all summer- has pretty, lacey foliage and cute yellow flowers.


On Nov 23, 2009, bonehead from Cedarhome, WA (Zone 8b) wrote:

Cheerful sprays of yellow tubular flowers May-Sep. Ferny foliage with a light outline. Self-sows much like johnny-jump-up, you never know where it will turn up. Easy to pull out, so not particulary invasive.

This plant did not survive its first winter. Although it could be because I bought it as a transplant, and did not grow it from seed. Wish it had worked out. May try later with seeds.


On Apr 2, 2008, Malus2006 from Coon Rapids, MN (Zone 4a) wrote:

Fully zone 4 hardy, tend to be a strange plant. It bruises and snap off easily when raking leaves in early spring as they send up leaves in late summer to fall. They goes dormant in long hot summer days and is strange about their seedling habits - sulk or spread rapidly. Like the above information, doesn't transplant well - currently I have two plants. Hardly rare - just difficult to transplant - often gardener get them when they hitchhike on another plant's pot from fellow growers - landscape companies' environment is too hostile for them to seed freely. The plants in my yard are in woodland shade and have some competitions hence their sulky habit.

I enjoy this plant very much. It always looks pretty and reblooms again and again. It does self-sow very easily so I share the babies. A quick hoe or pull would take care of the volunteers or perhaps a sprinkle of 'Preen'-type product around it would also help control the seedlings. I do not consider it invasive.

One of the few things that grows reliably and blooms all summer in our shady yard. The yellow flowers are an extra plus with so many shade plants flowering in more somber colors. Establishes quickly and seeds willingly, but not obnoxiously or far. Very delicate looking foliage. Growing in loamy/clay soil.

I live on 120 acres in central Florida and this plant shows up in the waste areas of my horse pastures during the winter months. It is especially prolific during our coldest weather (December through February) when it is often the only green thing there. We get freezing temperatures but it doesn't seem to freeze so must be quite cold hardy. After the plant completes its growth cycle and the seeds are produced it completely dies back and disappears during our hot, humid months. It is very palatable, and the horses seek it out like pigs on truffles. Unfortunately, ingestion causes mouth sores, gingivitis, colic and sudden death of horses if enough is ingested. I never planted this and diligently must pull it up to protect my equines. How it arrived in my pasture is a mystery, but in m... read more

Rare perennial in that is has beautiful foliage and attractive flowers the entrie summer! Likes semi-shade with gravely/sandy soil. Prospers around stone walls or in decorative gravel. Transplants poorly. Self sows and some may consider a 'weed' but it is very easily removed and somewhat picky as to location.


On Nov 18, 2002, lupinelover from Grove City, OH (Zone 6a) wrote:

This is a very long-flowering perennial; often blooms from April through November. Tends to self-sow exuberently in good growing conditions.

Established plants do not transplant well; best grown from seed, or establish new seedlings in pots for later transplanting.

Easy to grow from seed; bloomed the first year. The gray/blue fern-like foliage is very delicate-looking.
