After we had found Dionysia diapensiifolia and some, not very
attractive, plants
of Dionysia revoluta I went for a walk higher up the mountain the next
day.
Here, at an altitude of approx. 2600m I found some more Dionysia revoluta.
This time the plants were in full flower, some of them being rather large.
Also this species has a more widespread distribution, and there are even
some
subspecies known.
Later during our trip we found some more Dionysia revoluta on
Kuh-e Pashmaku, home of Dionysia iranshahrii.
Its not a difficult species in cultivation, after some years plants
tend to become
rather loose and require replacing by propagation.
