Herbaceous Perennials for Every Season

  • By Julie Kilpatrick
Their predicatable height and flowering time means herbaceous perennials are great in terms of garden planning. However, it can be quite a feat to ensure interest right throughout the year.

Unlike our seasonal bedding plants, herbaceous perennials remain in our borders all the year round but they don't flower for quite as long as the seasonal bedders, many of them flowering for no more than a month. But that doesn't mean you can't have colour all year round. Here are my favourites for achieving interest throughout the year:

January/February
