course these may now be reclassified as a different species (dividers vs
clumpers view of species), but I treat them as setosa. Some are very short and
some canadesis vs canadesis crosses are only 6" in height. I have various
arctica species from seed and have several white forms that look interesting.
There are many from SIGNA seeds,(various), are many others of forms that I
suspect have been crossed with other varieties (species, local variations?).
All together I have gone through about 800 seedlings ,plants.

- The only introduced seedling is Northern Valentine. Unfortunatly it has
developed sone viral/nematode disease and is not doing well in my garden at
this time. I have a great variety of seedlings undergoing evaluation at this
time. Some of the crosses have had wild variation in height with plants going
from 6" to 40" in height. A number of color variations. These include grape
colored, white, ones that are a mauve-pink in bud and on first opening but
then becoming white. Also some with white stripes on blue, some with almost
black spathes on flowers and some with almost black seed pods. And of course
many shades of blue/violet. As I mentioned the hybrids seem to tolerate open
garden conditions better. Some are more tender and do better if they have
afternoon shade. The canadesis seem to prefer shade where they grow better and
bloom better. I'm selecting for bud count and bloom duration and getting an
increasing number of flowers on the shorter varieties. I'm focusing on the
shorter varieties as them would seem to fill a gardening niche whereas th tall
varieties would have to compete with siberian. The height of 36-40" of some of
the seedlings had surprized me as one paarent was 15" and the other was about
20"
