Powerful Plant Performers Part 2: Perennials

By Cheri Stringer and Katie Kramer

In Part 2 of our Powerful Plant Performers series, we present perennials that thrive in our climate zone. Perennials are plants that endure several growing seasons and they can typically be divided after a few years to produce more flowers. If planted in the appropriate places, these plants frequently require less maintenance than annuals! Here are a few of our favorite perennials, tried and true by the TLC Gardens team:

 

Latin Name: Penstemon mexicali ‘P007S’

Common Name: Penstemon ‘Pikes Peak’

Why This Cultivar Rocks: This is a superb variety of penstemon that consistently outperforms all other varieties. The blooms retain color longer and are more profuse and uniform in their bloom size. Consistent performance is seen across multiple microclimates. 

 

 

Latin Name: Geranium ‘Gerwat’ PP12,175

Common Name: Geranium ‘Rozanne’

Why This Cultivar Rocks: Rozanne is hands down the best performer within the hardy geraniums selection available in Colorado, with profuse intense blooms that last longer than other varieties. Its blooms last from late spring to mid-autumn!

 

Latin Name: Dianthus gratianapolitanus 

Common Name: Dianthus ‘Firewitch’

Why This Cultivar Rocks: Dianthus ‘Firewitch’ is the best performer in its class because of two elements: return performance year to year and length of bloom time. When placed in a front location, the blooms of this perennial are so stunning that they will stop passing viewers in their tracks to inquire. Blooms are synchronized across the plant and are rarely affected by frost fluctuations.

TLC Garden’s award-winning Red Renaissance project utilized Dianthus ‘Firewitch’ at the entrance to the home among other areas. This Dianthus’ vivid colors added to the overall plant bed aesthetic with low-growing seasonal color. The boldness of the plants, the custom stone water feature, and the unique, custom seating purposely give the home’s entrance a grander feeling and a more pronounced sense of arrival.
