provide a rich contrast of colour. Many hardy geraniums are happy in shade, along with Primula, Viola and Brunnera. Once you do the research, you’ ll realise the huge array of possibilities.
Houttuynia cordata, sometimes known as fish mint or the chameleon plant, spreads like mad, especially near a pond or waterway. Bamboo
should also ring alarm bells.
• If you have clay soil which is often waterlogged( and then rock-solid during summer), don’ t despair. There really are plants that suit every place. Consider Astrantias, for example. They are a tough herbaceous perennial that can cope with many different conditions. You might need to give them some water
SPANISH BLUEBELLS
It’ s a beautiful plant, but even the“ well-behaved” clumping bamboos need to be planted using a root barrier, because they spread sideways very easily. The Spanish bluebell looks innocent but it’ s vigorous

• Think about plant shapes and texture as well as flower and foliage colour. Plants should look good together, or their individual charm will be lost.
Contrast creates interest; it’ s all about pattern. Use rounded shapes in different sizes, punctuated with
vertical plants and some spreading plants too.
Remember that colour looks better when it’ s repeated;
avoid having every colour under the sun.
