The Umbrella Plant is an evergreen perennial which forms a clump of erect stems with green foliage and small yellow-green flowers. It has a striking exotic appearance whilst also resembling the spokes of an umbrella; hence the common name of 'Umbrella Plant'. It is a moisture loving plant that grows well in ponds and bog gardens. The Cyperus involucratus has been awarded the Award of Garden Merit given by the Royal Horticultural Society (RHS), which helps gardeners make informed choices about plants.
Caring and Maintenance
This plant is semi-hardy. It will happily survive outside in warmer parts of the UK all year around. However, in colder climates, it should be overwintered in a greenhouse. Water adequately during dry and hot periods.
RHS Award of Garden Merit
The Award of Garden Merit or AGM is an award made to garden plants by the British Royal Horticultural Society after a period of assessment by the appropriate committees of the Society. Awards are made annually after plant trials (which may last for one or more years, depending on the type of plant being trialled) at RHS Garden, Wisley and other RHS gardens, or after observation of plants in specialist collections. This is intended to judge the plants' performance for conditions in the UK.
