A striking cushion-forming alpine native to the mountainous regions of Iran, Dionysia bornmuelleri produces dense mats of Farinose, evergreen foliage topped with vibrant yellow flowers in early spring. Prefers sharply drained, gritty soil and thrives in crevice gardens, troughs, or alpine houses. Requires excellent air circulation, cool roots, and protection from excess moisture.

Hardy to USDA Zone 5, but best grown with winter cover in wet climates.

I am still learning the ins and outs of cultivating these challenging gems of the middle Eastern Mountains. This one has rooted well from cuttings. So far clay pots and serious ventilation have been working. This one grew well in the Alpine frame overwinter. I have been following the Uppsala University book on Dionysia advice on soil and have been giving a dilute fertilizer solution at almost every watering. Jane McGary gave me a nice tufa chunk that I will be using as well. I’m happy to share tips on successes with this genus and I have some of the outstanding cushion species I’m working on propagating this spring, and I’m hoping that we can get these firmly established into American horticulture the way they have.
