Pennisetum alopecuroides ‘Rubrum’ (Purple Fountain Grass)
Pennisetum alopecuroides ‘Rubrum’, commonly known as Purple Fountain Grass, is a striking ornamental grass admired for its long, arching leaves in rich burgundy and its elegant, feathery flower spikes. Its deep colouring creates a beautiful contrast against green foliage and makes it a fantastic statement plant for borders, containers and patios. Fast-growing and full of movement, ‘Rubrum’ adds texture and a touch of drama to any outdoor space.
Light & Placement
-
Full sun is ideal and will bring out the richest colour in the foliage.
-
Some partial shade is tolerated, although the leaves may appear greener and flowering can be reduced.
-
Choose a sheltered position protected from strong winds, which can damage the long foliage.
-
Ideal for pots, borders and patios, where its graceful shape can be enjoyed up close.
-
Allow plenty of space for the foliage to arch naturally as the plant matures.
Watering & Soil
-
Water regularly while the plant is establishing, particularly during warm or dry weather.
-
Once established, it is moderately drought tolerant, but will benefit from watering during prolonged dry spells.
-
Allow the soil to dry slightly between watering and avoid waterlogged conditions.
-
Use a fertile, well-draining soil to encourage strong, healthy growth.
-
Cut back old foliage in late winter or early spring before new growth appears.
With its dramatic burgundy foliage and soft, bottlebrush-like flower spikes, Pennisetum ‘Rubrum’ brings colour, movement and texture to the garden. It looks particularly beautiful when planted alongside lighter green grasses or flowering plants, creating a bold and contemporary display.
