Roald Dahl English Shrub Rose

Rosa Ausowlish 'Roald Dahl'

The Story

Plant Bio

The genus Rosa comprises deciduous and evergreen woody shrubs native across the Northern Hemisphere, characterized by alternate pinnate leaves and multi-petaled flowers. Wild species typically inhabit open woodlands and scrublands, preferring fertile, well-drained soils and full sun to produce their characteristic summer blooms.

'Roald Dahl' is a compact, virtually thornless English shrub rose distinguished by its rich, soft apricot-colored double flowers that open from reddish-orange buds. This cultivar displays exceptional resistance to common fungal diseases and continues to bloom reliably in partial shade, requiring only three to five hours of direct sunlight.

Uses & Benefits:

Produces continuous flushes of deeply cupped, soft apricot rosettes with a moderate fruity tea fragrance on nearly thornless stems.

Features exceptionally high genetic disease resistance, reducing the need for chemical fungicide applications in the garden.

Provides pollen for generalist native bees and beneficial insects throughout its long blooming season.

Planting

How to Grow

Select a planting site that receives at least three to five hours of direct sunlight daily in fertile, well-drained soil.
Dig a planting hole twice as wide as the root ball and amend heavy soils with organic matter to ensure adequate drainage.
Plant the rose with the graft union positioned at or just below the soil level in colder climates, backfilling and watering thoroughly.
Apply a thick layer of organic mulch around the base to retain moisture, keeping the mulch clear of the main stems.

Pro Tip

Unlike traditional hybrid tea roses that require all-day sun, this cultivar thrives and blooms reliably with as little as three to five hours of direct sunlight daily.

Keep It Thriving

Care Guide

Do

Deadhead spent flowers regularly throughout the growing season to stimulate continuous repeat blooming.
Water deeply at the base of the plant rather than overhead to keep the foliage dry and minimize disease risk.
Apply a balanced rose fertilizer in early spring and again after the first heavy summer flush.

Don't

Do not prune heavily into old, completely leafless wood that lacks active buds, as recovery will be slow.
Do not allow the soil to become waterlogged, as this cultivar is intolerant of stagnant, heavy clay.
Do not use overhead sprinklers late in the evening, which encourages fungal spore germination on the leaves.
