Fountain grasses and other Pennisetum members can be sown either indoors or outdoors.
If sowing outdoors then do so in the first few months of spring and lightly cover the seeds.
Fountain grasses like to grow in sunny parts of the garden. Ideally the soil should be moist, well drained, and fertile.
If first growing indoors, then start about 7 or 8 weeks in advance.
The Fountain grass seeds should take about two to four weeks to germinate at 21 degrees Centigrade 70°F.
Transplant the young seedlings into the garden at about 45 to 90 cm (18 to 36 inches) apart. Do this about a week before the last frost of spring is expected.
Fountain grasses and other Pennisetum plants like to grow in moist soil so water regularly.
In cold areas, add mulch in the winter to protect the roots.
If growing perennial Pennisetum species, it is best to cut the plants down to the ground just after the last frost of spring. This encourages vigorous new growth.
If you require extra Fountain Grass plants, then they can be propagated by division; this should be done in the spring.
