Perennial plants are one of the largest groups of plants.

They offer color, shape, fragrance and seasonal textures. The variety is such that there are plants to suit all sizes and styles of garden.

Traditionally, perennials are grown in borders, using a wall or hedge as a backdrop to bring out all their splendor during summer.

But since most gardens are not large enough for long borders dedicated exclusively to perennials, they are usually planted in mixed borders and beds, along with shrubs, annuals, biennials, and bulbs that extend the season of interest.

• Clay soil is composed of more than 25 percent clay particles. These particles have a high moisture holding capacity and the soil is heavy to dig and can be waterlogged in winter (dry in summer).

• The loam soil is dark, rich in organic matter but balanced in minerals. It offers the best of all worlds, retaining enough water for the plants, but allowing excess moisture to drain away. This is the most desired type of garden soil, perfect for most plants.
