At a recent display of new plant trials at Smith Gardens in Marysville, Wash., Brian Minter observed several notable trends in plant breeding. The trials featured plants from numerous international breeders, showcasing the direction of hybridization and the traits deemed important for the future.
Heat and Drought Tolerance Take Center Stage
The biggest concern among breeders is weather tolerance, particularly heat and drought. The trial plants, set out in full sun either in containers or raised ground beds, had a very short timeline to become established—a key factor for gardening success. Annuals dominated the trials, with perennials close behind.
Begonias of all types are expanding in popularity, and Minter was amazed at how these formerly shade-loving plants performed in full sun. Last year's top pick, the large-flowered European variety Fragrant Falls, continued to impress with its quality, disease resistance, and sun tolerance. Though more upright, it has a nice spillover habit ideal for hanging baskets.
New Begonia Varieties Shine
Traditional sun-loving begonia baskets were on display from many companies, but the Beauvilia series from Europe stood out with colors ranging from dark salmon and orange to brilliant red. The Benary Company from Germany featured a unique fibrous begonia called b. Wookie Pink Splash, an attractive pink and white bicolor with a gently trailing habit, started from seed.
Still among the most impressive large-flowering begonias is the I’Conia series, including Portofino Yellow, Portofino Valencia Pink, and Bachelorette Red, all thriving in full hot sun with no signs of foliage or flower burn. Minter's favorite new giant-flowered fibrous begonia series, Mega Cool, featured a wide range of colors and performed exceptionally in large containers, making them a must-have for hot patios and balconies.
Syngenta and Dummen Orange Collaboration
Not to be outdone, I Candy XL begonias from Syngenta, headquartered in Switzerland, were also very impressive. Sun-tolerant with a beautiful trailing habit and spectacular blooms in a wide range of colors, they are sought after for containers and hanging baskets. With Syngenta and Dummen Orange joining forces, Minter predicts a collection of new plants in the coming years.
Other notable varieties included the Heatopia Lobelia in three colors: magenta, light blue, and dark blue. The trials demonstrated that heat and drought tolerance are now essential traits for new plant introductions, and breeders are rising to the challenge.
