Fantastic little annual! This plant can take whatever conditions summer dishes out. If it gets too hot and dry it simply rests a bit, and just as soon as conditions moderate slightly it bursts into bloom again. I definitely plan on using lots of Blue Pimpernel in my future garden displays!

Average water needs; do not over-water.

Propagation Methods:
From seed: sow indoors before last frost; direct sow after last frost
Seed Collecting: Allow pods to dry on plant; break open to collect seeds ... properly cleaned, seed can be successfully stored.
