Sow and Plant

Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.

Notes

Scabiosas make great cut flowers, and many varieties are fragrant. Colours include lavender, pink, rose, dark red, white and soft yellow. Perennial forms are available, but not in the colour range of seed-sown annual scabiosa.

Harvesting

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.

Troubleshooting

Scabiosa plants may need staking to keep them upright so that the stems do not twist.
