Swertia perennis
FELWORT, STAR SWERTIA
- Unit price
- / per
This hardy perennial is native to parts of Europe and Western North America. Does well in moist, boggy areas with full sun. Blooms from July to September. Can either have 4 or 5 petals on the blossoms, ranging from dark blue to light purple in colour with dark-purple veination. Used to be a more common wetland plant, but habitat fragmentation has negatively impacted the populations of these plants.
Type: Hardy perennial
Hardiness zone: 4-8
Height: 14", 35cm
Location: Sun
Seeds per packet: 15
Sow just under the surface of the soil and water in. Leave them at room temperature for 4 weeks. This helps break the phytohormones which inhibit germination. They will not grow yet. Then a cooling period is required. Cover them with plastic and place in a fridge for 6 weeks. Be sure they stay moist. After the cold stratification period they are then brought back to a cool room (15-18°C, 59-68°F) for them to germinate. Germination can be erratic, generally 30-90 days after the warming period, though some can take longer.
