Colourful Foliage Plants
Flowers come and go, but for most plants in the garden, leaves remain throughout the year. Choose plants with colour in the leaves, and you will be adding colour to the garden for the whole year.
It’s surprising how many different colours can be found in foliage, if you take the time to look. We often don’t notice their potential effect, because plants with coloured foliage are frequently mixed in with green foliage, and as a result the effect is lost.
Ways to Use Coloured Foliage
1. Colour theme gardens where foliage is used in harmony or in contrast. Combinations you can use include white, silver and gold; cool coloured (blue, purple, green) or hot coloured (red, orange, pink, yellow) flowers and foliage.
2. Mass plantings of coloured foliage can create a significant splash amongst green plants.
3. Hedging – using a single foliage colour, or two or more foliage colours to create a tapestry effect.
A plant’s foliage colour may change throughout the year, depending on the season or the stage of growth. In some plants the best foliage colours are the new growth flushes in spring, and also perhaps early autumn.
Give the plant optimal care (ie. fertilising, watering, trimming, and the right position in sun or shade) and it will reward you with more intensely coloured, healthy foliage.

What is Variegation?
Variegation is often caused by a virus. Nutrient deficiencies and insect attack can also cause variegation. If an entire shoot reverts to green, it is often a virus-free shoot. Cut the shoot out to retain the variegated effect. Also watch the zinc levels – high levels of zinc in the plant may inhibit the virus and help turn the plant back to green.
