Rhododendron Hachmann's Metallica

Hardy Hybrid Rhododendron

Unusual lilac flowers with a dark purple blotch

A compact shrub that is covered in striking lavender-blue flowers in late May and early June. These beautiful, richly coloured flowers have a prominent dark violet blotch and speckling.


This hardy hybrid rhododendron can be planted in beds, borders, or on slopes and looks great in cottage and informal gardens. It can be located in full sun or partial shade. Protect the flowers from frost damage.


This plant loves any type of soil that is acidic, so for best results use a good amount of ericaceous compost when planting.

This compact and hardy plant got its name from Holger Hachmann, who bred rhododendrons in northern Germany.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. If planting in a bed or border test the soil to establish its pH. If the soil is too alkali it is best to grow your plant in a container. In either case prepare the area by digging a hole twice the size of the pot. Dig ericaceous compost into the base of the hole, if planting in a container use ericaceous compost to fill the pot. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
