More information

Two different varieties of Diosma. These are frost-tender shrubs with aromatic heather-like foliage, perfectly suited for container gardening and coastal gardens. Their flowering, a pale pink for the first variety and a bright pink for the second, is early and remarkably long-lasting: it starts in February and continues until June-July. Highly drought-resistant, they perish below -5 °C. Diosma can only be grown in non-calcareous, well-drained soil.

Description

This pair of Diosma will flower the terrace or a coastal garden for long weeks, between February and June-July. These Diosmas are South African undershrubs not exceeding 45 cm in height and 55 cm in width, beautifully rounded, with evergreen foliage that is reminiscent of heather. They have a surprising spicy fragrance when touched. Their tiny star-shaped flowers bloom in a dense and airy mass. Diosmas are very resistant to drought in open ground and have a great effect in a dry rockery or a gravel bed. Elsewhere, in a planter or a pot, they can spend the winter protected from the cold.

This duo consists of:

1 Diosma hirsuta 'Pink Fountain': pale pink flowers

1 Diosma hirsuta 'Pink Diamond': brighter pink flowers

Diosma hirsuta is a shrub plant native to the Cape region in South Africa, particularly the valleys and slopes of the Cederberg, where it grows on sandy, non-calcareous, well-drained soils. It cannot withstand frost below -5 °C. It is a very pretty plant for ericaceous or sandy soil, ideal for enhancing a bed or a rockery by the sea. These bushes can be associated with heathers or low-growing scrub vegetation such as rockroses, lavenders, thymes, or Teucrium. Leave a spacing of 40-50 cm between each plant when creating the bed, always place the taller varieties in the background so that each one is clearly visible. In most regions, the Diosmas in this duo will make beautiful plants for a slightly heated orangery or veranda.

Planting and care

Diosma hirsuta is only cultivated in open ground or in mild climates. It will thrive in light, well-drained, even sandy or rocky, acidic to neutral soil (it does not like limestone). It tolerates sea spray well. Plant it after the last frost. It will flourish in the sun. Under these conditions, it is hardy down to -5°/-6°C and can live for many years. Once well established, it will not need any watering in the summer. However, it will be essential, in regions further away from the sea, to grow it in a large pot to store it during the winter, in a bright but unheated room. To shape it, you can lightly prune the stems after flowering to encourage the plant to branch out.

Pot cultivation:

Ensure good drainage at the bottom of the pot. Use a lightweight substrate, enriched with leaf compost and coarse sand, and add a little slow-release fertiliser at the end of winter. Do not bury the collar of the plant. Water regularly in the summer, allowing the soil to dry out a little between waterings.
