Best New Annual Flowers of 2020
January 21st, 2020
A new line of disease-resistant impatiens, a sunflower that thinks it’s a blooming bush, and a velvety trailer that people can’t resist touching top the list of interesting new annual flowers debuting in 2020.
Growers, local garden centers, and other plant experts picked those and more for the four-part, best-new-plants series I write each January – a good month for gardeners to plan what to plant in the coming season.
The article on best new vegetables, herbs, and fruits of 2020 ran last Tuesday, Jan. 14. The best new perennial flowers of 2020 runs next Tuesday, Jan. 28, and the best new trees and shrubs of 2020 runs Feb. 4.
Some of the following new annual flowers are available in seeds or plants online and in some plant catalogs. Most also will show up in plant form in local garden centers beginning in late April to early May.
The details:
Impatiens Beacon series
Breeders from Syngenta Flowers last year gave us a new line of bedding impatiens called Imara XDR that fought off the deadly downy mildew disease that’s plagued our once-favorite annual flower since 2012.
New for 2020 is a separate line from PanAmerican Seed that looks to be an even better, fuller choice.
Named Beacon, this six-color line looks and performs like the impatiens of old, except without the threat of collapsing in mid-summer from disease.
Deb Shearer, co-owner of Ashcombe Farm and Greenhouses in Monroe Twp., picks Beacon as her favorite new annual for their durability and because they’re “more compact than Imara. Hopefully, there will be new colors in addition to the original six.”
Both Beacons and Imaras bloomed full steam ahead in Penn State’s Trial Gardens last summer while older ones died next to them. The Beacons scored slightly higher than the Imaras.
“They were stellar,” Trial Gardens Director Sinclair Adam said of the Beacon series. “I didn’t see any problems with disease.”
Venelin Dimitrov, senior product manager at Bucks County’s W. Atlee Burpee Co., likes the Beacon ‘Paradise Mix’ blend and reports that those were healthy and still blooming well into October in Burpee’s trial garden.
Stauffers of Kissel Hill buyer Todd Kephart also likes Beacons and says some growers are starting to grow only Imaras and Beacons because they’re so much more disease-resistant than other impatiens.
Beacons grow about 18 inches tall in shade, part shade, and with adequate soil moisture, even full sun.
