In the garden

An evergreen member of the Ericaceae, Rhododendron trichostomum deep form carries its foliage year-round and produces its flowering display from April to June. Plants perform best where they receive partial shade and are protected from prevailing winds; a north-facing, sheltered aspect reduces exposure that can dry foliage. Set in a moisture-retentive loam with an acid pH, water regularly during establishment and keep the root-run consistently moist without waterlogging. H5 (hardy) indicates this form tolerates typical UK winters, but exposed sites increase the risk of winter desiccation so position and shelter matter more than absolute temperature rating. Place it in shrub borders, under the dappled shade of larger trees or within collections of acid-loving plants where soil conditions match its needs. Give Rhododendron trichostomum deep form a sheltered, north-facing spot so its evergreen leaves and spring flower buds are protected from drying winds and late frost.
