Trillium ovatum
WESTERN COAST TRILLIUM
- Unit price
- / per
The most widespread of the western North American trilliums, Trillium ovatum varies greatly within its range. T. ovatum is a perennial herbaceous plant that spreads by means of underground rhizomes. At maturity, each plant has one or two flowering scapes, each 20 to 50 cm (8 to 19.5 in) in length.
Typically the flower opens white and becomes pink with age, but in the Smith River Canyon area of northern California and southern Oregon, the petals become almost barn-red.
Type: Hardy perennial
Height: 20"
Location: Part sun or part shade
Hardiness zones: 5-8
Seeds per packet: 3
Sow just under the surface of the soil and water in. First keep them at room temperature for 6 weeks. This helps break the phytohormones which inhibit germination. Then cover them with plastic to retain moisture, and then place in a fridge for 8 weeks. Then bring them to a cool room (approximately 12C, 54F) for 8 weeks for germination. They may be growing at this point, though often they need a second cold period. If they are not growing cover them with plastic and place in a fridge for another 6-8 weeks. Be sure they stay moist. After the second cold stratification period they are then brought back to a cool (12-15C, 54-59F) room for them to germinate. This double cold period is not always needed, but sometimes necessary, and is very normal for these seeds. Germination is in 30-90 days after the second warming period.
The leaves contain calcium oxalate crystals and crystal raphide, and should not be consumed by humans.
