Dierama pulcherrimum is a distinctive-looking perennial with tall arching stems of bell-shaped, flowers. Each stem drops with the weight of the flowers which earns them the common name of Angel's Fishing Rods.
Dierama pulcherrimum album, also known as 'Snowbells' is a lovely colour-break in Dieramas. Delicate, tubular, white bells with dark centres, dangle from graceful arching stems. This will be an exceptional addition to any perennial border. Seedlings may also produce the odd bicolour or palest pink.
The flowers appear in mid summer and hang above clumps of grey-green, grass-like leaves. These delicate flowers look like grasses when the buds first emerge. Each bud expands into a pendant flower so graceful that it earns its other favorite common name, Fairy wands.
The stems may look delicate, but are actually very tough and appear to tremble in the breeze. Perfect for introducing movement to a well-drained border in a sunny, sheltered site or for overhanging water.
Initially slow to establish, Dierama looks particularly good with early autumn-flowering ornamental grasses. They are excellent for cutting or as a specimen plant surrounded by a low-growing groundcover.
Dierama pulcherrimum is a desirable addition to any herbaceous border or gravel garden, they also lend themselves to pot culture.
Sowing: Sow seeds as soon as possible.
Sow Dierama seeds on the surface of a moist, well drained seed sowing mix (John Innes No 1 or similar) at about 17°C (62°F). They will normally only germinate with light,, so cover with only a light sprinkling of compost or grit to about 5mm deep. Use a translucent cover to allow light in and to keep the compost humid and warm (do not place in direct sunlight). No heat is needed, they can be place in a cold frame or cold greenhouse.
Dierama are often spring germinators but occasionally may be slow and erratic taking between 30 and 180 days. Don’t throw away the pots too soon.
Prick out and grow on seedlings in 7.5cm (3in) pots in a frost-free place, such as a cold greenhouse. Plant out in good garden soil.the following spring. When transplanting be careful not to damage their brittle roots. Plant out from spring, and settle them where they are going to overwinter before the end of August.
Choose an open, sunny position in a fertile, loamy, moist, but well-drained, soil, which doesn’t dry out in summer or become waterlogged in winter. Heavier clay soils and lighter sandy soils should be improved by incorporating well-rotted organic matter.
They can also be planted in containers of fertile, but well-drained, potting media, such as John Innes No.2, but, generally, they grow and flower better when planted in the soil.
Dierama corms are best planted in spring, with the corms 5 to 7cm (2 to 3in) deep. Containerised plants should be planted so that the top of the compost is level with the surrounding soil. Alternatively, Dierama do well in raised beds.
Dieramas need adequate space to look their best. They can be planted in borders or gravel gardens, and look good grown with ornamental grasses. They are attractive near water, but careful positioning is necessary as the corms must not get too wet over winter. Dierama prefer to be on the dry side overwinter, but if too dry the tops may die off entirely.
Water well in dry summers and apply a general purpose fertiliser such as blood, fish and bone or Growmore in spring. Dieramas need very little pruning as they are semi-evergreen. However, old, unsightly foliage can be cut away; this is usually done in spring. Plants may be divided in early spring or immediately after flowering; but this should only be undertaken occasionally as plants are slow to re-establish.
Not overly hardy, the plants withstand light frosts but is not likely to respond well to soil temperatures below minus 5°C (23°F) and protection in the form of a thick mulch of fleece should be given in very cold areas.
Once established these plants soon form a lovely dense clump. They will tolerate quite a bit of crowding in the garden but eventually, perhaps once every five years, they may get overcrowded, indicated by a decreasing amount of flowers.
When this occurs dig up the corms after flowering, divide them into smaller clumps and spread them out. Care must be taken during this process as the roots are very brittle. They will not flower in the year that they have been dug as they resent disturbance.
Separated corms can be used as a gift for ‘green-fingered’ friends, take to the church fete or moved to suitable parts of the garden. Dierama make sensational plants for pots.

Dierama are native to South Africa and the Drakensberg mountains, usually found in moist, mountainous grassland. The original form of D. pulcherrimum was found in the Eastern Cape province of South Africa. It was found to be restricted to the area between the Keiskama and Buffalo Rivers near East London.
Dierama is a genus of 44 species of evergreen, clump forming, summer flowering hardy perennials. All members of the genus have upright narrow leaves and tall wiry arching stems, which carry many pendulous flowers in mid-summer, but they vary in colour, vigour, shape of flowers and timing of flowering.
Plants grow from what botanists call a corm. The corms build up year by year into chains, similar to Crocosmia.
Dierama are in the Iris family – Iridaceae.
Pronounced dye-ur-AY-muh pull-KAIR-ih-mum.
The genus name Dierama comes from the ancient Greek word meaning "funnel" or "like a bell" alluding to the shape of the flowers.
The species name "Pulcherrimum" is Greek and means 'the most beautiful'.
The arching stems and flowers are the base for the most romantic common names, like Angel's Fishing Rod, Wedding Bells, Wand flower, Flowering Grass, Hairbells, Fairybells, African Harebell and Wandflower.
