PropagationPropagation Material: Seeds
Description: This phacelia propagates readily from seed. Because it self-sows so freely, its often easiest to bypass seed collection and simply transplant the self-sown seedlings.
Seed Collection: Since this phacelia begins flowering at the bottom of the stalk and progesses upward, seeds will mature first in the basal fruits. Seeds in the upper capsules are generally ready to collect when the lower capsules have split. Cleaned seeds should be stored dry in sealed, refrigerated containers.
Commercially Avail: yes
Maintenance: Because it self-sows vigorously and is short-lived, dying soon after it blooms in its second year, Phacelia bipinnatifida should be allowed plenty of room in a naturalistic, woodland setting to move around as it wishes. If you want to maintain it in precise spots, transplant seedlings in the fall to preferred locations.
