How to Grow and Care
The seeds of Cirsium can be sown in either autumn or after the last frost of spring. They should be sown at a depth of 0.12 inches (3 mm). If grown indoors first, then Cirsium takes about 2 to 3 weeks to germinate at 70 to 75 °F (21 to 24 °C). The seedlings should be planted out in early spring when it is still possible to get a frost with a spacing of about 2 feet (60 cm).
Cirsium thrives in full sun and poor, average, or reach soil that is moist but well-drained. Plants require little care, but deadheading limits their tendency to self-sow. They generally self-sow only in moderation, and unlike weedy thistles, the seedlings are easy to pull up. Use Thistles in mixed beds, herb gardens, or meadow-like plantings.

Native to the western Mediterranean.
