The modern style of mixed perennial plantings uses repetition of the same plants or similar plants to create a total picture. The plants are woven together rather than being set out in contrasting blocks. Even in small gardens this effect is possible as shown here.
The flat topped, umbellifer flowers are Cenolophium denudatum and the bold early flowering spikes are provided by Veronicastrum sibiricum ‘Red Arrows’. The theme in June is violet and pink, but next month orange and yellow will play the leading role here.
