amsonia การใช้

• ARKANSAS AMSONIA ( A . hubrectii ) is a newcomer to the garden scene.
• "Amsonia orientalis " is the only European member of its genus.
• "Amsonia " is named in honor of the American physician John Amson.
• In May, Amsonia flowers create a melody of blues in sunny to bright shade areas.
• In any case, it is generally sold as Amsonia montana and is perfect for smaller gardens.
• Though the various blue stars ( Amsonias ) differ in size and leaf form, each is a golden presence in fall gardens.
• "Amsonia tomentosa " is a short, woody plant with many erect stems rarely reaching half a meter in height.
• To keep the Arkansas amsonia height more in line with my small borders, I cut them back to a foot after they finish flowering.
• Arkansas amsonia is so strikingly different from the other two blue stars that I'm surprised botanists aren't debating its classification, too.
• Miscanthus and holly are my mainstays, but there are always surprises, like the evergreen leaves of arum Italicum or the yellow skeletons of Solomon's seal or amsonia.
• Today, 88 of these species and one genera ( " Amsonia " ) still bear the valid names provided by Walter in his " Flora ".
• One other species ( " Amsonia elliptica " ( Thunb . ) Roem . & Schult . ) is found in East Asia, while all the others are native to North America.
• By true blue, do we mean saturated cornflower or gentian blue, or pastel sky blue, or the grayer forget-me-not blue, the steel blue of amsonia, or the darker ink and sapphire blues?
• Platycodon, woodland phlox, catnip, Lobelia syphilitica, Siberian iris, columbine, campanula, centaurea, echinopsis, gentian, hardy geraniums, amsonia, and adenanthera are perennials that flower tolerably well in light shade or part-day sun.
• So in pursuit of the elusive 12-month garden, he has been refocusing on hardy plants with luminous fall foliage, such as reddening blueberry bushes and glistening golden amsonia, and late-season surprises like the brilliant red seeds of peony ovata, an unusual woodland peony.
• The asters clash with the sweep of amsonia, a prairie grass that turns pumpkin yellow in the fall, and the flaming leaves of the sassafras trees that Darke, 48, the former curator of Longwood Gardens, in Kennett Square, Pa ., planted from seedlings dug up in the meadow.
• Even from the bathroom, there's a gorgeous view of the yellow sweet shrub Calycanthus floridus Edith Wilder, which smells like strawberries in the spring; the deep ruby red sedum; black gum; a red viburnum called Winterthur; and the amsonia that runs like a river through this patch of the Piedmont.
• The flowers, mainly blue and white, include asters, Campanula latifolia, amsonia ( an underappreciated favorite and a great second fiddle ), Siberian iris, and catnip, of which she says, " it's not an exciting blue, but it's very long blooming and has gray-green leaves ."
• But mostly they want flowers : Verbena bonariensis, with tiny lavender flowers that dance in the breeze; Ammi majus Green Mist, which looks like a minty green Queen Anne's lace; and amsonia, a grass that covers itself in sky-blue flowers in spring then turns orange in fall .
