Sonchus asper
Prickly Sow-thistle
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 Oleraceus is an annual herb, often considered invasive, with dandelion-like leaves and flowers. The leaves can be eaten as salad greens, or cooked (like spinach). This is one of the species used in Chinese cuisine as kucài (??; lit. bitter vegetable). Blanching, or boiling, removes bitterness. Sonchus asper is an annual or biennial herb sometimes reaching a height of 200 cm (almost 7 ') with spiny leaves and yellow dandelion-like flowers. The plant is very similar to Sonchus Oleraceus

Flowering
From Early Summer TO Late Summer
Dandelion-like flowers appear in Summer
Planting
From Mid Spring TO Late Spring
Generally speaking, it is unlikely that one would want to plant this sow-thistle! 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.
