Top Performing Annuals at CSU

September 24, 2013 - 10:22

Now that the summer has come and gone and fall is officially here, many of the country's top trial gardens are coming to a close. With peak growing season just around the corner, now is probably a good time to evaluate many of the top performing varieties from various trials.

Colorado State University recently announced the results from its annual flower trials. It was a hot and very wet summer; as a matter of fact, one storm in early July resulted in a tree in the CSU garden getting struck by lightning, which damaged parts of the garden.

But still many of the plants pulled through and showed an impressive display. Here are some of the trial favorites:

Best of Show - Lantana 'Lucky Sunrise Rose' (Ball FloraPlant)

Lantanas are known for their heat tolerance, and this variety boasted a superior display of blooms throughout the summer and into the fall.The bright flowers were prolific and the dark foliage color made the flowers stand out. 

Best New Variety - Petunia 'Cascadias Indian Summer' (Danziger)

This variety showcases a true color breakthrough with unique shades of pink, yellow and orange. Flowering was strong throughout the season, and the plant maintained its shape with a nice cascading habit.

Best Novelty - Pennisetum 'Graceful Grasses Fireworks' (Proven Winners)

This unique grass features colorful foliage that varies through the summer depending on light and temperature. The narrow leaf blades have an attractive combination of green mixed with white and pink streaks. Plants are medium height and work well in the landscape.

Best New Guinea Impatiens - 'Super Sonic Orange Ice' (Syngenta Flowers)

The large flowers on this plant open orange and mature into a hot coral color with a violet center, resulting in a nice bicolor effect. The dark foliage sets off the flowers, which bloom above the foliage, creating an impressive show.

Best Verbena - 'Temari Patio Hot Pink' (Suntory)

The deep-pink flowers on this verbena were noted for their non-fading color. Flowering was strong all season, and plant vigor was excellent while maintaining a good overall growth habit.
