Aciphylla dieffenbachii
SOFT SPEARGRASS, CHATHAM ISLAND SPEARGRASS
- Unit price
- / per
A medium-sized species with glaucus silvery-blue fine foliage. Produces large umbels with soft-yellow flowers. Valued for both it's foliage and flowers, as well as the seed heads, which are golden as the seed ripens. It does not like high summer temperatures and is a perfect replacement for Agave and Yucca.
Type: Hardy perennial
Hardiness zones: 8-10
Height: 33", 100cm
Location: Sun or part sun
Seeds per packet: 5
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 and may start after 30 days, though some can take up to a year. Do not discard the planting container as patience is required.
