Planting young plants

From Mid Autumn TO Late Spring

Pennisetum are very hardy so they could be planted in the autumn, however late spring is the best time. Newly-bought plants take at least three years to clump up to a decent size and many nurseries specialising in grasses recommend planting in threes and fives. The slightest breeze will add an extra dimension to the winter garden, as well as movement, so it’s important to position all Pennisetum where they catch the light. Don’t tuck them away in deep shade.
