****New! Just launched at Chelsea Flower Show 2019 where it was shortlisted for RHS Chelsea Plant of the Year. Plants available Autumn 2019****

(H5) May flowering. The flowers open a light greenish yellow, flushed yellowish pink at edges, with a glowing deeper yellow centre. Neat rounded truss on a compact plant with good leaves.Height 100-125cm in 10 years. Requires moist acid soils.

Although bred by Edmund de Rothschild in 1966, it was not registered with the RHS until 1996, and we are the first nursery to propagate it from the world famous Exbury Gardens. We think this is probably the best new variety ever to be raised at Exbury. It is perfect for the smaller garden, having a neat compact habit, and flowering profusely from a young age.
We will be launching this at Chelsea Flower Show in 2019, to mark the Centenary of Lionel de Rothschild starting his gardens at Exbury. The flowers open a light greenish yellow, flushed yellowish pink at the edges, with a glowing deeper yellow centre. The flowers are strong and sit in a neat rounded truss above a compact plant with good foliage. It grows to 100-125cm in 10 years, and requires moist acid soil.

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 flowering varieties. Avoid waterlogged sites.

Pruning

Rhododendrons and Camellias: Not normally required. Tidy wayward shoots after flowering.

Evergreen azaleas and Bloombux can be clipped into a low hedge.

Magnolias and Acers: Formative pruning when young to shape into a tree or bush.

Deadheading

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