Sonchus canariensis
Giant Sowthistle
Most Sonchus are annuals, with a few that are perennials, and, rarely, a shrub. Most have a basal rosette of deeply-toothed leaves, upright stems with clasping leaves and yellow, dandelion-like flowers Sonchus canariensis is only found in the Canary Islands, off the coast of North Africa. It is palm tree shaped and grows 8' tall, with fern-like foliage, huge heads of 100 or more dandelion-like flowers at the tops of the branches in Spring and Summer.

Sonchus canariensis
Most Sonchus are annuals, with a few that are perennials, and, rarely, a shrub. Most have a basal rosette of deeply-toothed leaves, upright stems with clasping leaves and yellow, dandelion-like flowers Sonchus canariensis is only found in the Canary Islands, off the coast of North Africa. It is palm tree shaped and grows 8' tall, with fern-like foliage, huge heads of 100 or more dandelion-like flowers at the tops of the branches in Spring and Summer.
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.
