Where can I get the seed for this plant?
Thank you.

I bought one of these about 2 years ago as a "Pathway Plant", and it's still alive. It's on the east side, at the edge of my path, and gets little sun. I bought 3 more and will plant them at the edge of the path in a sunnier location.

Bought Mount Atlas daisy this summer and planted it on the hot sun-facing side of the sidewalk to the house. Hasn't survived the winter, so my zip code report isn't quite reliable yet.

Heat & drought tolerant is an understatement. Mine was planted along a gravel driveway in ugly, unimproved Nevada baked clay soil. Full sun with summer temps well over 100F for weeks on end. Did I mention average humidity of less than 10%?

It not only survives but thrives AND has been evergreen for me. This is a MUST HAVE plant for all desert gardeners.

I tried 3 times to find a micro-habitat on my rock hill where it would be happy enough to survive in what is supposed to be zone 5, but it just never made it through a winter. It's so beautiful either closed or open!

Mat forming perennial with ferny type foliage. The white daisy like flowers have a red stripe on the reverse side of the petals. Making a pretty bloom even when the blooms are closed. Flowers close in the evenings and when cloudy. Needs full sun and good drainage. Good to use as a ground cover or in rock gardens.Heat and drought tolerant.
