Gardeners' Notes:

Beautiful healthy edging, about 4" high, 10" wide, and very dense. Started from seed in March, transplanted in June. Bloomed almost immediately after planting and now they are the last thing blooming in my garden; they have survived several frosts. We had our first snow today so I expect that will be the end of them. I am saving seeds and will plant more next year to edge other beds. I never noticed much of a scent to them, however.

These flowers are super for filling in gaps in your garden. My mom has them planted in between roses and I use them in my front yard with California Poppies. They spread easily and the snails don't eat them. I don't kill snails so I just try to find plants that aren't damaged by them. These fall into that category. Very easy, self-sowing, low water need. Also great as filler for hanging baskets. It looks like a blanket of snow in the yard.

Planted in winter from seed (in trays and then 2" pots). Probably I planted too early. I was not impressed with what was happening. Looked dead or dying. Spring came and I - as a "what the heck" kind of thing - planted these in a spot of the garden that is not primary. I figured that I had nothing to lose.

They took off. Really a carpet of white white. Dense and low. healthy, healthy, healthy.

Needless to say, I moved them.

I am totally impressed and will plant these from now on - I just won't start them so early.
