Title: Gymnospermiums
Post by: Janis Ruksans on March 27, 2010, 05:55:47 PM: Gymnospermiums are very nice tuberous "bulbs" from Berberidaceae family.
Here two most widely grown
Gymnospermium albertii from near Chimgan, Uzbekistan
Gymnospermium altaicum from Mramornaja Gora (Marble Mount) in Altai mountains, Siberia, Russia

Yes, I grew it many years outside and it was selfsowing. Only soil must be very sandy with excellent drainage. I'm in zone 4-5.

Sand is no problem in my area. So the Gymnospermium can come ;D

At first I wrongly named it G. sylvaticum, which grow in Afganistan and is unknown in cultivation.

These lovely Berberidaceae should be more widely grown, not only for the flowers but the attractive divided foliage. I grew Gymnospermium altaicum outside for about 8 years, it finally succumbed a couple years ago when shaded and encroached upon by nearby shrubs.

Post by: Janis Ruksans on April 04, 2010, 05:02:38 PM: There are two Gymnospermiums which I can't to seperate - G. altaicum from Altai mountains in Siberia and G. odessanum from Ukraina and Roumania. The very great distance between both forth to think - they must be different. Between them 3 other species are growing. But in Greece are growing subsp. pelloponesiacum as syubsp. of G. altaicum. I got some seeds of it from Gothenburg BG and now it blooms for the first time. Still small, but nice.

Thanks for posting these Janis, they're such delightful miniature species. :)
