More new varieties of vegetables and annual flowers are developed each year than perennial flowers and woody plants, probably because it takes multiple years to evaluate their key traits such as winter hardiness, which isn’t a factor in testing new vegetables and annual flowers. Each year, though, there is a nice sampling of new perennials.
Perennial flowers are all about patience. On average, it takes a perennial until its third year to establish itself enough for peak performance and bloom.
Patience is also helpful when searching for new varieties of perennials, which are more likely to be carried by locally owned garden centers than by national chains. Even locally owned garden centers can’t carry all the thousands of plant varieties available, and carrying new types often requires them to discontinue other varieties, simply for lack of space to grow everything.
If you’re especially interested in a new perennial type, ask your local garden center whether they plan to grow or sell it. Even if they can’t stock it this season, maybe they will next year, if requested. Perennials are a long-term investment, and new types might be worth the wait.
