The summer heat and dryness of location seem to do a lot re the fate of
setosa. I grow quite a few and find that the species varieties can be quite
intolerant of direct sun particularly if it is dry. Some that have been
discarded but on a compost pile that is in the shade seem to last forever but
then procede to die when given a second chance and planted in the sun. On the
otherhand crosses of one collected species to a species collected from another
location will do much better. Of course weather selection plays a role in this
as the less tolerant ones die out early. I'm in zone 4/5 USA (zone 6b
Canadian). On of my seedlings "Northern Valentine" did very well down in Texas
at the convention but was planted in the same location with the Louisianas.
