Flowering Season

From Early Summer TO Early Autumn

Giant Scabious bloom from early Summer through to early Autumn

 

Planting Outdoors

From Mid Spring TO Early Summer

Plant out seedlings when they are big enough to handle. Plant in full sun, in most, fertile well-draining soil, in a sheltered site.

 

Planting Outdoors in Autumn

From Early Autumn TO Late Autumn

Seedlings that were sown in late Summer can be planted out when they are big enough to handle, and after hardening-off, if they were grown under glass. Plant them in a sunny, well-draining, sheltered site, in fertile soil.

 

Propagation by Seed

From Early Spring TO Mid Spring

Fill a seed tray with seed compost,water and allow to drain.Sprinkle seeds over the surface allowing roughly 25mm space between seeds and cover with a thin layer of compost. Put tray in a clear polythene bag and place on a windowsill. When seedlings show remove plastic bag.When the second pair of leaves appear on the seedlings thin out to 50mm spacing by removing the weakest looking plants. After 2 or 3 weeks and when danger of frost has passed plants can then be planted outside into required position, after hardening-off.
