Hi Jim,

I grow G. albertii and altaicum, Bongardia chrysogonum and Leontice
ewersmanii.   The latter is the ultimate source of frustration - I get seed
every year (from Jan Jilek), it germinates and the seedlings grow on - but
it dies every summer during dormancy.  It makes weird twisted elongated
tubers that head straight to the bottom of a 5" pot the first season.  It
seems to be incredibly moisture sensitive, I'm not sure if it too damp too
long or I give it moisture too soon in the fall.  I'll keep trying.

None of these plants increase vegetatively but they will set seed, probably
needing multiple clones.  I have seedlings of the two Gymnospermium
species - some in their second year, others fresh germinations.  I love
these two, and would describe them as beautiful, especially if you have
clones with a very strong red color in the stems which contrasts beautifully
with the yellow flowers with red veins.

Bongardia is a curiosity and I only grow it because I have it.  The leaves
are kind of nicely marked at the bases but it soon becomes a rangy thing and
the flowers are far from spectacular.  Interesting though !

All of the above are completely hardy here.

I have had seed from Jan Jilek, Henrik Zetterlund at Gothenburg BG and
Vlastimil Pilous, as well as some of my own seed.  Tubers can be had from
some 'alpine' sources in the UK - e.g. Kath Dryden.

I love them and it sounds like you are growing albertii very well - nice and
compact and well colored.
