Lots of us love plants, and we love to find new plants in garden centres, succumb to temptation and arrive home with our new purchases, then decide where to place them.
Diversity of plant types is good for nature, it is good for gardeners, adding interest and beauty to our gardens.
The danger with using lots of different plant varieties is that the planting scheme becomes a mish-mash or jumble of plants and the results are a confusing and unharmonious gathering of plants.
Harmony in the design can be achieved in different ways: colour of flowers, colours of foliage, plants of similar styles and also, plants with similar shapes.
In The Pylon Garden here at The Paddock, I have repeated leafy tussocks of varieties of Phormium (New Zealand Flax) and Astelia, amongst others. See the video below.
