Need Assistance? The Rhododendron is a very popular genus of shrubs, especially as many have large colourful flowers in spring after an often long winter. They are generally evergreen except the deciduous Azaleas - a lovely fragrant one with yellow flowers is Rhododendron luteum - grows to 4m but they tend to only grow well in acidic soils. If they look as if they are poorly yellowing leaves often due to lack of nutrition then you can feed them special plant food obtained from garden centres.
The first known cultivated Rhododendron species was Rhododendron hirsutum, which was found growing in the Alps in the sixteenth century, and was cultivated in the century following by John Tradescent the younger.
However, the most widely grown Rhododendron species in the past has been Rhododendron ponticum which was discovered by the Black Sea at the beginning of the eighteenth century. It was brought to England in by plant collectors and was widely grown as an indoor container plant byAs it became more popular it began to be used as a landscaping shrub.
Unfortunately, this plant has proved to be very invasive. In Britain and Ireland the main problem is that each mature rhododendron shrub can produce up to a million seeds. These are distributed by the wind especially if the shrubs are on hillsides or other prominent positions and the species will naturalise on heaths, in wooded areas and even on lightly-grazed grasslands.
It is known to reduce populations of nesting birds, is poisonous to livestock and is not eaten by many insects. It can carry an infection called Phytophora ramorum too which infects native species of trees etc. It grows in shade and in full sun, but it grows so tall and so thick that other plant species cannot grow underneath it. This is especially a problem in a woodland ecosystem which relies on light being available to different species occupying different tiers.
EG in Snowdonia National Park, it has now spread to over 2, ha. The National Trust and other bodies such as the British Trust for Conservation Volunteers and Wildlife Trusts often conduct task days in winter to remove Rhodedendron ponticum…..
I can recommend it! Plant other species of Rhododendron in your garden. Less invasive cultivars can be found in garden centres and nurseries - they have the added advantage of often only growing to a maximum height of 1m or 1.

QBARS - v32n1 Growing Rhododendron Seedlings Indoors Under Artificial Light
An Azalea plant is the national flower of Nepal, and is part of an ancient group of plants dating back million of years. They are related to rhododendrons and blueberries and are descendents of Asian shrubs. Azaleas can also be used as a centerpiece for weddings or to replace expensive cut flower arrangements in your home or office. Azaleas have delicate, funnel shaped, lipped flowers that can be red, pink, white, yellow, purple and even bi-color. These plants are considered poisonous and should be kept away from pets and children. Azalea plants have terminal blooms which means the entire plant flowers at one time making a beautiful display.
