Gardeners' Notes:

In my Houston back yard it is a lush WEED SMOTHERING groundciver blooming may-June, dappled to full shade. Grows very well under trees, so as far as im concerned, it is valuable in the landscape. It always has a neat appearance. My plants are bordered by a deck, fence and edging and it fills the space. I don't consider it an invasive nuisance,however I accidentally sprayed it with round up and it failed to kill it.

Beautiful in moist shade. Spreads by underground runners which are very brittle, as are the leaf stems, and easily damaged by rough treatment. Shiny heart shaped leaves remain with enough irrigation. A drift of this plant is ethereal.

Nothing negative to say about it other than how easily it is damaged by wind, critters running through it, or careless maintenance.

Snow poppy is undoubtedly beautiful when in bloom, even when just the leaves are present, but I would think twice about planting it in certain situations - it has spread like mad in my garden, popping up even from within dense plantings of monkey grass, which usually keeps most other plants out. I find I have to pull up quite a bit of it every year to keep it in bounds. (Baton Rouge, LA, zone 8b)

I bought this in bloom last February and it continued to bloom through March, went dormant for the summer, and the leaves have just sprung up again. I have it planted under a pine tree, where it gets mostly shade with some light afternoon sun and the soil remains moist. I love the light, airy look of this flower!

I really like this poppy. It blooms late here in my zone 5b garden, provides an excellent groundcover (as others have already mentioned), and while it spreads, it is not invasive here--at least not yet. It is fleshy, and when I have tried to share it with friends, it is hard to get down deep enough to get enough root. Nonetheless, even with just a bit of root, it moves on to the next garden just fine after a bit of protest.

This vigorous perennial from Eastern China spreads by rhizomes making a groundcover 16 inches high. White flowers, 2 inches across, in late spring, summer.

This plant does quite well for me interplanted with Peacock ginger under oaks here in New Orleans. When the ginger goes dormant, the snow poppies begin their growth season. They never go completely dormant, though, so some always show through the gingers - just less leaves in the warmer months.

I grow this in south eastern Australia in an area that is both cold (down to -10 C) and hot (up to 40 C). An attractive, ground covering perennial with juicy, fleshy stems that are prone to wind damage. Shelter from strong winds and hot sun. Delicate, four petalled, pure white flowers (which show up well in the shade) held well above the large, smooth, lobed leaves. Useful for shady areas where many plants are reluctant to flower. Spreads by underground rhizomes which are quite brittle and easily broken. Good looking leaves. best allowed to wander around and establish themselves anywhere you can grow ferns, astilbes etc

A creeping plant that spreads by rhizomes from Eastern China.Has pure white 2 inch poppy like blooms.Makes a good ground cover for shady areas.It spreads and in fertile soil can become invasive.Likes moist well drained soil in light shade.Will do fine in full sun if the soil is not let dry out in the summer.
