Gardeners are always looking ahead. We have to! It takes time to go from seed to bloom or harvest.

So, in the middle of Summer 2022, we’re looking forward to Summer 2023 and the new varieties we’ll see (and grow) next year.

Whetting our appetite for new flowers is the announcement this week of the first 2023 All-America Selections winners. The AAS committee dribbles out its winners list, and the first to be revealed are three perennials that are improvements on old favorites.

National perennial winner is a pretty blue sage that can handle both extreme cold and blast-furnace heat. Blue By You salvia ( https://tinyurl.com/m5bm86cd ), developed by Chicago-based Darwin Perennials, offers six months of bloom with little effort.

Blue salvia
Blue By You salvia is a national AAS winner.
“With excellent winter hardiness and heat tolerance, Blue by You will be a new favorite in your perennial, pollinator, cutting and container gardens,” predicts the AAS committee. “Bursting with bright blue blossoms from late spring into fall, you’ll get repeat blooms throughout the season when spent blooms are removed.”

A hybrid between Salvia nemorosa and Salvia pratensis , Blue by You is a bee magnet. It needs average irrigation and grows about 20 to 22 inches tall. Another plus: Deer don’t like it.

Two regional winners also were revealed: A hybrid coneflower and a groundcover Shasta daisy.

Artisan Yellow Ombre echinacea ( https://tinyurl.com/5xyxwy6w ), developed by PanAmerican Seed (which does a lot of plant breeding and testing in Yolo County), is an improved coneflower with strong, straight stems – great for cutting. Named the Southeast and Northwest regional winner, it grows 24 to 30 inches tall and blooms continuously for months.

(Both Darwin Perennials and PanAmerican Seed are part of Ball Horticultural.)

“Artisan Yellow Ombre is a great plant for anyone wanting vibrant color all season long in their perennial garden, or to use as a cut flower,” says the AAS committee.

Golden coneflowers
Artisan Yellow Ombre coneflower was named a regional winner.

“This is the first F1 hybrid echinacea series that comes in individual colors. This winner, with an intense golden yellow bloom along with graduated colors of yellow, is a gem in the garden. AAS Judges were impressed with the uniform growth habit, vibrantly colored flowers, and multi-branched plants that produce a prolific number of blooms. Pollinators will flock to this echinacea, and gardeners will love this low-maintenance, long-blooming beauty.”

Other colors in the Artisan series of coneflowers (so far) include Red Ombre and Soft Orange.

The most unusual All-America Selection winner may be the groundcover Shasta daisy Carpet Angel ( https://tinyurl.com/5n873mun ); it was named the West regional winner. The only AAS winner of its kind, it’s also the first AAS winner for breeder Green Fuse Botanicals of Santa Paula, Calif.

“Green Fuse Botanicals’ First Light Perennials is a program of first-year flowering perennials that are day-length neutral, meaning earlier blooms that continue all season long,” explains the AAS committee. “Large 3-inch flowers boast a second inner frilly bloom adding to the unique look of Carpet Angel.

"Growing only to a height of 6 inches, this unique Leucanthemum can act as a groundcover spreading up to 20 inches wide. Fantastic branching on this new AAS winner means more flower stems sporting beautiful pure white blooms that look like angels dancing over a carpet of dark green foliage. A little deadheading of spent flowers will reward you with even more blooms.”

Look for these plants in nurseries and plant catalogs next spring.

Garden Checklist for week of April 21

This week there’s plenty to keep gardeners busy. With no rain in the immediate forecast, remember to irrigate any new transplants.

* Weed, weed, weed! Get them before they flower and go to seed.

* April is the last chance to plant citrus trees such as dwarf orange, lemon and kumquat. These trees also look good in landscaping and provide fresh fruit in winter.

* Smell orange blossoms? Feed citrus trees with a low dose of balanced fertilizer (such as 10-10-10) during bloom to help set fruit. Keep an eye out for ants.

* Apply slow-release fertilizer to the lawn.

* Thoroughly clean debris from the bottom of outdoor ponds or fountains.

* Spring brings a flush of rapid growth, and that means your garden is really hungry. Feed shrubs and trees with a slow-release fertilizer. Or mulch with a 1-inch layer of compost.

* Azaleas and camellias looking a little yellow? If leaves are turning yellow between the veins, give them a boost with chelated iron.

* Trim dead flowers but not leaves from spring-flowering bulbs such as daffodils and tulips. Those leaves gather energy to create next year's flowers. Also, give the bulbs a fertilizer boost after bloom.

* Pinch chrysanthemums back to 12 inches for fall flowers. Cut old stems to the ground.

* Mulch around plants to conserve moisture and control weeds.

* From seed, plant beans, beets, cantaloupes, carrots, corn, cucumbers, melons, radishes and squash.

* Plant onion sets.

* In the flower garden, plant seeds for asters, cosmos, celosia, marigolds, salvia, sunflowers and zinnias.

* Transplant petunias, zinnias, geraniums and other summer bloomers.

* Plant perennials and dahlia tubers for summer bloom.

* Mid to late April is about the last chance to plant summer bulbs, such as gladiolus and tuberous begonias.

* Transplant lettuce seedlings. Choose varieties that mature quickly such as loose leaf.
