Long Blooming Perennials at Plant Paradise Country Gardens

Long blooming perennials are the backbone to successfully creating a garden of continuous bloom. At Plant Paradise Country Gardens one of the questions we get asked most often is “How do you create a perennial garden of continuous bloom? Continuous bloom is achievable with the right plant choices and choosing long blooming perennials are the key to success.

To determine which perennials to grow in your garden, start by asking yourself a few questions. What are the light conditions in my garden? Is it a sunny or shady location? Is the soil dry or moist? What growing zone am I in? Answers to all of these questions will be a starting point to determine the best perennials that will grow in your garden.

It all starts with choosing the right plant for the right location. The average perennial flower will bloom from two to three weeks, so choosing perennials that bloom for months is an added bonus. These long-blooming perennials create the foundation of building a garden of continuous bloom.

Choosing perennials with outstanding foliage cannot be emphasized enough. Foliage provides colour, texture and form in the garden when the flowers are not in bloom.
