Flowering

From Early Summer TO Late Summer

Dandelion-like flowers appear in Summer

 

Planting

From Mid Spring TO Late Spring

If grown outdoors, plant in a sheltered, sunny or partially sunny site, in moist, free-draining soil. Frost tender, but the root will often survive, even though the leaves are killed by frost. If grown in a container, grow in free-draining, loam-based compost, and place outdoors through Summer, then overwinter in a frost free place.

 

Propagating by seed

From Mid Spring TO Late Spring

Propagate by seed by sowing seed in situ, after the risk of frost has passed, in moist, free draining soil in a sunny, or partially sunny, sheltered site, or in a container.
