Sow and Plant
Sow scabiosa seeds indoors in early spring and set seedlings out two weeks before your last spring frost is expected. Transplant carefully, without disturbing the roots.
Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.
Scabiosas make great cut flowers, and many varieties are fragrant. Colors include lavender, pink, rose, dark red, white and soft yellow. Perennial forms are available, but not in the color range of seed-sown annual scabiosa.
Harvest stems to use as cut flowers as soon as the blossoms open. Clip off old blossoms every week or so to prolong bloom time.
Scabiosa plants may need staking to keep them upright so that the stems do not twist.
