(H6) A rare plant with single small white flowers at the ends of wiry little branches, in May. A quaint and pretty little shrub from Southern Japan, with small leaves. Height 25-50cm in 10 years.

Low evergreen azalea, though mainly deciduous in winter. It grows to 75cm high, with slender stems covered with appressed, linear, dark brown bristles, that point towards the end of the shoot. Leaves narrowly oval or obovate, 5-20mm long and 2-5mm wide, dark green, with bristly hairs on the margins. Flowers mostly solitary at the end of short twigs. Corolla white, funnel-shaped, about 20mm across, with 5 oblong lobes and 5 stamens.

Native of Honshu, Kyushu, and Shikoku in Southern Japan. This quaint and pretty little shrub is not often seen, though it is said to be quite hardy. It was introduced for Messrs Veitch by Charles Maries, and flowered with them in 1882.

The Basics

Ideal soil

Acidic soil, good organic content, pH 4.5-6.0. Inkarho range of rhododendrons will tolerate soils up to pH7.5

Sun or Shade

Light dappled shade is best for most varieties.

Shelter

Refer to hardiness rating. Give young plants protection.

Site Selection

Avoid close to trees, roots, invasive weeds, walls, hot patios, dry banks and waterlogged soils. Do not use weed matting or stone mulch

Plant spacing

Use the height shown in 10 years as a guide to the distance between each plant. Allow room for plant to fill out. If planting closer for instant impact, be prepared to move plants after a few years.

Compost

  • 3 litre pot, dig in 10-20 litres of ericaceous compost.
  • 7.5 litre pot, dig in 20-30 litres of ericaceous compost.
  • 70-80cm specimen, dig in 60 litres of ericaceous compost.
  • 100-120cm specimen, dig in 120 litres of ericaceous compost.

Planting depth

Plant high in the ground, with the top of the rootball visible.

Feeding

Slow-release ericaceous feed recommended in March and straight after flowering.

Mulch

Recommended every few years.

Water

The key ingredient! Keep moist all season, especially the critical time at end of June for flower bud initiation. Tap water is better than no water. Heavy dose at least once per week in dry weather.

Drainage

Ensure good drainage in winter, especially with yellow varieties. Avoid waterlogged sites.

Pruning

Not normally required. Tidy wayward shoots after flowering. Evergreen azaleas and Bloombux can be clipped into a low hedge.

Deadheading

Remove old flower-heads, particularly on young or weak plants.
