How to Grow Featherbells and other Stenanthium Plants
It is best to grow Featherbells, Featherfleece, and other Stenanthium from bulbs. These should be buried at about 10 to 13 cm (4 to 5 inches) deep, at the start of spring.
Stenanthium bulbs should be spaced at about 30 to 60 cm (12 to 24 inches) apart. Locate plants so they can be grown in a sunny or partially shaded part of the garden.
This should have good drainage and a moist acidic soil.
It is possible to grow this plant from seeds. Sow the seeds into flats and lightly cover, sink the flats into the ground in a shaded location, and cover with glass. Germination should take from one month to six months.
Allow the seedlings to grow in situ for one growing season, then transplant to their final location following the last frost of spring.
Caring for Stenanthium
It is fairly easy to care for Stenanthium species in the garden. The ground that they grow in should be composted and mulched in the spring, and they require regular watering. If you require more plants then they can be propagated by division in the autumn.
