Guide to growing Fountain Grass - Pennisetum

Pennisetum genus grasses may be half hardy annuals, half hardy perennials or hardy perennials.

Pennisetum blooms from the end of summer through the early months of autumn and they carry many spikes of fuzzy / feathery flowers that reach from 60cm to 1.2M in height. Some common names for Pennisetum are Fountain Grass and Feathertop.

How to grow Fountain Grass

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. Transplant the young seedlings into the garden about 45 to 90cm apart about a week before the last frost of spring is expected.

Caring for Feather grass

Fountain grasses like to grow in moist soil so water regularly. In cold area 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 to help with vigorous new growth. If you require more Fountain Grass plants then they can be propagated by division; this should be done in the spring.
