I still can’t believe that for as many years I have been growing flowers that I have most recently come to discover the amazing world of China asters. Back in the day, when we were growing for grocery store sales, the only varieties on the market were run of the mill Matsumoto and spray types. There was nothing beautiful or exciting about them, so I rarely included them in the garden. But a few years ago, I stumbled on a German grower offering the most incredible range of varieties that I had never seen before.
Last summer we grew over 40 varieties and this summer grew 40 more and I am now a passionate champion for China asters. What makes these plants so great is that they can be grown from seed, are easy to grow and flower at a time when the garden is starting to fade. As the day length shortens, this group of plants is prompted to begin flowering.
In addition to lasting an incredibly long time in the vase, China asters come in a dazzling rainbow of colors and a wide range of flower shapes and sizes, including huge feathered blossoms, sturdy sprays of miniature buttons, tight domed flower heads and soft rose-like blooms.
China asters are typically sown 6-8 weeks before the last spring frost and transplanted out after the weather has sufficiently warmed. Like other cold sensitive plants, such a zinnias, basil and celosia, it’s important to wait to tuck these into the garden until all danger of frost has passed.
We grow our China asters in landscape fabric and space plants 9 inches apart with 5 rows per bed. Once blooms appear, plants tend to topple over under the weight of the flower display, so be sure to give these guys plenty of support while the plants are still small.
We use a layer of Hortonova netting stretched horizontally about 12 inches above the ground. Netting is held by in place by metal hoops that we made with our Johnny’s Quick Hoops Bender. Any type of stake, wooden or metal, will work just fine. As the plants grow, they push up through the grid of netting and get the support they need.
After plants are tucked into the ground they just hang out for the better part of summer and are pretty boring in the landscape. I’ve found myself fretting over them, wondering if they are going to do anything. But as summer comes to a close, they start making buds and elongating in the waning light.
As the rest of the garden starts to wind down and fall apart, China asters come into their prime and along with dahlias, helping finish the flower season strong. They are a must grow for late summer and early autumn bouquets.
Harvest flowers when they are about half way open and strip the foliage off the lower half of the stems and place them into water with flower food. A vase life of 7-10+ days can be expected.
China asters are sensitive to wet weather and the petals will brown if not harvested on time. So be sure to pick them regularly for the best looking blooms.
All in all, we’ve grown close to 80 different mixes and individual varieties.
Over in the Floret Shop you will find my absolute favorites. Peach and blush have become extremely popular colors with floral designers and brides. So if you have weddings in your future, you might want to consider the following varieties:
Harlekin Light Rose: This tall, feminine beauty is smothered in an abundance of the sweetest soft, nearly ballerina-pink blooms. Disc-shaped blooms have a fluffy appearance from the hundreds of quilled, tubular petals covering them.
Rose Quartz Mix: This feminine mix features warm pink tones, including dusty rose, blush and ballet slipper pink. Delicate ruffled blooms look like pretty soft pillows.
Valkyrie Pink: Palm-sized blooms on this mauve-pink beauty are reminiscent of the color of sea anemones. Buds are lighter than the mature flowers, giving plants a wonderful color range. Long, pointed flower petals resemble rosy cactus flowers, and as blooms are opening, the center petals are swirled.
Lady Coral Chamois: With the softest peachy-blush blooms, this romantic beauty has a glowing quality. Each plant is smothered in at least a dozen stems topped with ruffled, feminine flowers.
Tower Chamois Apricot: One of the most beautiful and well loved asters, Chamois Apricot is a must grow. Each vigorous plant is loaded with dozens of glowing peachy-pink blooms that are perfect for flower arranging and wedding work.
Valkyrie Chamois: Palm-sized blooms on this striking variety are stunning. Long, pointed flower petals resemble bird feathers, and as blooms are opening, the center petals are swirled.
If you’re looking for some beautiful, hardworking additions to the late summer cutting garden, look no further. China asters shine when the rest of the garden starts to fade, rewarding you with a bumper crop of glowing, textural blooms.
