QAre you WS in containers or in ground ?
COnditions here may be similar?
I am doing a few wildflowers direct in ground as I have lots of seeds..
FOr things with expensive or rare seeds, I sow in containers.
Find a spot that stays cool in the spring. With our changeable weather you don't want things warming up too early and then getting killed by a cold spell. Also don't forget about wind.
I think the most challenging thing for me has been keeping things watered.
