I was going to throw these out but these may interest someone up north seeing as blooms are going on right now.
Q - tips swabs of pollen stored in aluminum foil in fridge for about 4 weeks
S. x 'Wriggleyana'
S. x 'Catesbaei'
S. flava - not much left on the Q tips but enough to do 1 pollination
If this doesnt interest anyone by next week I will be throwing them out.
