We've got to get back to the Gardens!
2022 RRTG HIGHLIGHTS:

Here are some standouts from last summer:

Best overall performance Annual – Begonia Prism Sunset (Westoff) This Begonia was overflowing with large flowers in shades of orange, coral, and rose all summer long. A great shade container choice to brighten up any dark area in your garden. The Begonia had the most visitor favorites pick throughout the summer. The flowers are held above the foliage on a well branched plant habit.  

Best overall performance perennial – Kniphofia uvaria Glowstick (Darwin Perennials) Packed with bright golden flower spikes from summer until fall. The grass like foliage also adds a fine texture to the garden. This plant is drought tolerant, a pollinator powerhouse, and is low maintenance.

Best Pollinator friendly Annual – Salvia interspecific Salgoon Lake Baikal (hilverdaFlorist) This is a well branched, sturdy, flowering powerhouse that provides flowers all summer long. This Salvia was continuously visited by hummingbirds, butterflies, and bees. Great in a sunny landscape or patio pots.

Best Pollinator friendly Perennial – Echinacea SunMagic Vintage Red (Bull Plant Genetics) Butterflies and insects love this variety. Deep reddish-pink flowers are held on sturdy stems. Well branched with over 20 flower buds on each plant. This series consists of 6 colors, and all are uniform in habit. A pollinator magnet. 

Best heat tolerant Annual – Bracteantha Granvia Gold (Suntory Flowers) This vigorous plant loves the heat and never slowed down in the stressful hot summer days. The flowers stood proudly and abundantly all summer above a mounded plant habit. 

Best heat tolerant Perennial – Veronica Seaside (Garden Choice) This Veronica is larger and has show stopping blue flower spikes all summer long. Loves the heat and sun of summer and did not show signs of powdery mildew until extremely late in the season when the days started getting shorter and the nights cooler. This Veronica also tolerates salt. 

You can find photos and performance data on all of these and everything in our trials on our Trial Data Page.
