In the six days of the California Spring Trials, there’s always more to share than we can fit into one issue. In the June edition of Greenhouse Management, we looked at a selection of the debuted annuals during the trials (See it at bit.ly/2tGiTvi). While the trials typically showcase annuals, many breeders take the opportunity to also put their best perennials in the limelight. “Perennials are rapidly becoming a very interesting product class for growers, retailers, landscapers,” Mike Klopmeyer of Darwin Perennials told us. This month, we step away from annuals to hone in on some of the new perennials we saw this year.
Darwin Perennials introduced 19 new perennials this year, including two new armerias in the Dreameria series. Sweet Dreams and Daydream flower through the summer and fall, and will overwinter to Zone 6. Rose Marvel (pictured with hummingbird), a new Salvia nemorosa in the Marvel family, boasts large flowers, hardiness to Zone 4, and a longer flowering window than other Salvia nemorosas on the market. Its dark bracts make it an attractive plant even when after flowering. Learn more about these and other new introductions in this video: bit.ly/2tdjcNG
The most popular perennial at the Proven Winners stop this year was Primo ‘Wild Rose’ heuchera, due to its vigorous habit, large size and vibrant, eye-catching color that stays through the seasons.

Last year, Dümmen Orange debuted a new perennial combination program, with plants that are bred to time together, are daylength neutral and early flowering. This year, the company added several new varieties to the program, including coreopsis Moonswirl (pictured, top of planter), that can be mixed and matched for a dynamic combination.

At the GroLink stop, PlantHaven thought outside of the pot for its display of Aguja ‘Black Scallop,” which is usually seen as a groundcover. At Spring Trials, ‘Black Scallop’ was turned into ball-shaped topiaries, which Robert Bett, president of PlantHaven, said looked like something out of Dr. Seuss. This variety was a new addition to PlantHaven’s Icon program, a collection of older industry favorites.Attendees were also excited about a Corydalis on display, Hillier ‘Porcelain Blue.’ Its vibrant and fragrant aqua-blue flowers bloom nonstop throughout the summer and fall.

At the Windmill Nursery stop, Terra Nova took a fresh approach to grouping and displaying its perennials. New and previous introductions with similar characteristics were set up in displays that highlighted their respective qualities like water-wise nature, ease for landscaping use and attractiveness to pollinators.

Pacific Plug & Liner
At Pacific Plug & Liner, we were literally surrounded by perennials at “Camp Perennial,” PP&L’s name for its stop this year. Attendees were “campers” and could collect merit badges as they visited each “campsite” where different perennials were showcased.
