Hello there,
Superb and beautiful plants!
I have tried a few times to grow Dionysia and failed to keep them alive. Some I purchased managed to last a few months and others only a few weeks. I keep meaning to try again but I think I need more time to give them the care that they need. Perhaps in the future I will try again when I have more time and a suitable alpine house for them.
Thanks for posting the pictures. It is encouraging me to try again.

Alasdair, many thanks for your friendly comment. You are right, Dionysias are not the easiest alpines
in cultivation but the perfect cushions and their profuse flowering make them simply irresistible.
We still have good memories of a visit to Ardfearn Nursery during the Alpines 91 conference,it seemed
to us like a paradise with plants which he have never seen before.

I am desperate to grow Dionysias well but manage to kill them with great regularity. Initially plants seem to be doing ok but then suddenly I get dieback of one or a few rosettes for no obvious reason before the entire cushion heads into a rapid decline. I can only assume that I am too heavy-handed with watering but I also find that Dionysia cushions are fairly prone to greenfly attack. Most greenfly treatments involve spraying the foliage which surely can’t be good for Dionysia. Systemic treatments are undoubtedly effective but as most aphids seem to be in rather than on top of the cushion their dead bodies lodged in the cushion must surely be a focus for fungal infection. I would be grateful for any cultivation advice from the skilled growers who post on the forum.

Dionysia aretioides -This plant is a good number of years old having died back only to recover on a number of occasions. It now lives in the centre of a cold frame which has wire sides.
