Saw-worts is a genus of about 300 species of flowering plants in the thistle tribe within the daisy family, native to cool temperate and arctic regions of Asia, Europe, and North America. They are perennial herbaceous plants, ranging in height from dwarf alpine species 5 to 10 cm tall, to tall thistle-like plants up to 3 m tall. The flowers form in a dense head of small capitula, often surrounded by dense white to purple woolly hairs; the individual florets are also white to purple.
Water:
Saw-worts prefers consistent moisture, thriving in conditions similar to its native habitat. It has moderate drought tolerance and requires weekly watering, especially during active growth phases. Proper hydration is crucial for supporting its lush foliage and flowering, without risking waterlogging.
Propagation:
Saw-worts can be propagated by seed, division, and cuttings, with success dependent on light, temperature, and well-draining soil. Seeds may require stratification. Key steps include sowing during the right season, maintaining moisture and temperature, and transplanting robust seedlings. Division is best done in spring or autumn.
