Gardeners' Notes:

Positive John_in_Garland On Jun 9, 2010, John_in_Garland from Garland, TX wrote:

Growing in afternoon sun under a small tree. Stems tend to lie prostrate and grow away from shade. Stems readily rooted and original center plant didn't overwiter, so plant is 'migrating'. Light bloom all summer, 1" flowers. Not as floriferous as I expected.

Neutral Debndal On Jun 19, 2008, Debndal from Coppell, TX (Zone 8a) wrote:

I purchased this plant because it is reported to bloom well in shade - it blooms in shade, but not well. I have also planted it in partial sun and it does very well there and I like it. If you purchase this plant with the intention to put in it complete shade, I think you will be disappointed.

came up all on it's own next to the road at my place. Never watered or fed it anything and it has been blooming now for a few weeks.

A prolific bloomer that readily reseeds. A nice addition to a xeric garden. I have them growing among my prickly pears and agaves.

Orange Zexmenia is native to the dry,calcareous,gravelly, and rocky soils of the the Edwards Plateau and the South Texas Plains. It can reach a height of 1 to 2.5 feet and a 3 foot width. It blooms well in sun or shade. A single yellowish-orange flower blooms at the end of a long single stem and appears from May to September. The flower head is composed of several disk flowers and 7 to 15 ray flowers. Rough in texture and covered with stiff hairs (as are the stems), the 2-3 inch in length leaves have coarsely-toothed margins and are eaten by white-tailed deer and cattle. It attracts butterflies both as a nectar source and the feeding of larvae. This is an excellent xeriscape plant which deserves to be used more in the cultivated garden.
