Scabosia is a member of the family Dipsacaceae and includes both flowering annuals and perennials. It grows well and is hardy planted within USDA planting zones 4 through 9 as a spring, flowering plant. Flowers up to 3 inches across are born on 12- to 36-inch spikes and, depending upon the cultivar, range in colors of white, various purples, pinks, salmon, rose and blue. Scabosia is often known as "pincushion flower" because of its appearance. Gardeners can collect seed from spent flower heads and sow them for their spring gardens. Scabosia is a hardy plant relatively easy to propagate.
Plant the scabosia seed approximately eight weeks before frosty weather leaves your area. This gives the seeds time to germinate and seedlings time to establish themselves before planting in warm, spring gardens. Starting the seeds early allows for early springtime blooms.
Fill a container or planting tray that drains with an organically rich, lightweight, well-draining potting mix that does not have a tendency to retain water. Scabosia grows best in rich, lightweight soils.
Sow the scabosia seeds on top of the soil medium and cover with a very light application of soil. Planting the seeds too deep will impede the germination process.
Water the container or tray to moisten the potting medium. Keep the soil moist but not saturated with water while the seeds are germinating.
Place the container or planting tray in an area that receives light and a consistent temperature of 70 degrees Fahrenheit. Scabosia seeds require warmth for them to germinate properly. The seeds should germinate in approximately two to three weeks.
Set the scabosia seedlings outdoors in a sunny to partially sunny area when the warm weather of spring returns.
Planting Seeds Directly in the Ground
Plant the scabosia seed directly into the garden once the warm weather of spring has returned and all signs of frost or freezes have left your area.
Select an area in the garden that receives full to partial sunlight. Warm areas of scabosia’s planting zone should sow the seeds in an area that receives partial shade during the afternoon hours.
Amend the planting site with compost, peat or manure to make the soil rich. Scabosia prefers growing outdoors in a lightweight soil that is rich in organic material and drains well.
Scatter the seeds on top of the soil and cover with a light covering of soil. Covering the seed with too much soil prevents them from germinating.
Water the area to moisten the soil and keep the area moist while the seeds germinate. The seedlings will emerge in approximately two to three weeks. Keep the area moist while the plants are growing there.
