Carduus acanthoides Seeds | Spiny Plumeless Thistle
LATIN NAME: Carduus acanthoides
COMMON NAME: Spiny Plumeless Thistle
Plant Profile
Spiny Plumeless Thistle (Carduus acanthoides) is a bristly biennial of the daisy family (Asteraceae), native to Europe and western Asia and naturalised in North America. It forms a spiny rosette in its first year, then a branching, winged, fiercely armed stem 30-150 cm tall, bearing narrow, spine-fringed leaves and small purple-pink thistle heads. Its seeds feed goldfinches, and the plant is a declared weed in several countries.
Science & Biotechnology
The species features in the wider study of the Carduus group, and its traits make it a useful subject for work on germination biology, cultivation and ornamental selection. This biological control research represents an important area of integrated pest management for noxious thistle species across affected agricultural regions. Little about its garden performance is mysterious; it has been grown and observed for a very long time.
Uses & Benefits
Spiny Plumeless Thistle works well in borders, containers and dedicated beds. Understanding its biology remains important mainly for effective management and control rather than any deliberate cultivation. A plant that has settled in will get along with only routine care.
Thistles of this genus share the liver-tonic folk reputation of their milk-thistle cousin, though less intensely studied; young stems were once peeled and eaten.
Growing from Seed
Spiny Plumeless Thistle is one of those generous plants that come along well from seed. Sow the seeds evenly over the surface and cover lightly in a loose, well-drained seed compost, keep the sowing evenly moist, and give the pot or tray bright light. Shift the seedlings into small pots as soon as they can be handled, and give them bright light until planting-out time.
Our Take
Spiny Plumeless Thistle is the kind of plant that rewards a permanent spot. Minor errors in timing or watering rarely cost the grower the crop.
