How to Grow Alliums, Allium, Ornamental Onions, Flowering Onions How to Grow Alliums, Allium, Ornamental Onions, Flowering... http://www.gardeners.com/Growing-Alliums/7371,default,pg.html Alliums for the Flower Garden Onions, shallots and gardlic are members of the allium family that belong in the vegetable garden. But there are many ornamental alliums that deserve a hearty welcome in your perennial gardens. Alliums are plants of exquisite beauty in both flower and leaf, with tough constitutions. These easy-to-grow bulbs come in a broad palette of colors, heights, bloom times and flower forms. They make excellent cut flowers for fresh or dried bouquets. Even crowded gardens can accommodate a few alliums because they don't take up much space. What's more, alliums are relatively resistant to deer, voles, chipmunks, and rabbits Ordinary Onions They're Not There are more than 700 different types of alliums in the world. It wasn't until the late 1800s that this vast group of plants started to intrigue plant lovers. Russian botanists began collecting some of the spectacular alliums from Central Asia and introducing them to avid horticulturists through the Imperial Botanical Garden in St. Petersburg. Of course, it didn't take long for the In this border, the Purple Sensation allium consummate plant hunters, the British, to bridges the gap between spring and early get wind of this "new" family of garden- summer-flowering perennials. worthy plants. Their expeditions yielded many more interesting alliums varieties. Hardy, Easy-Care, Deer- and Rodent- Resistant Ornamental alliums are hardy to zone 4 and they have very undemanding cultural requirements. They will grow in most any soil, as long as it is well-drained. Alliums adore sunlight and will perform best when they can bask in it all day long. Since most of them multiply naturally, they can be left untouched in the same area for years. Alliums are drought-tolerant plants that actually prefer to be grown on the dry side. There are no serious diseases or insect pests that bother them. And you won't ever have to worry about rodents or deer, since they seem to have no appreciation for the taste of onions — ornamental or otherwise. Just remember, there's only one time of year you can plant alliums: in the fall.

This type of allium is usually sold as a potted plant, and may be more available in spring than fall. Favorite Alliums There are dozens of varieties in cultivation; here are some profiles of some of the best. Purple Sensation: the 2″ to 4″ diameter purple globes bloom in early June, right after the late tulips. Purple Sensation's sturdy stems rise 24″ to 30″ high, so the flowers appear to float above the foliage of newly emerging perennials. Globemaster and Gladiator: The tallest and most architectural alliums have huge, globe- shaped flowerheads on 3- to 4-foot stems. Bloom time is early to mid-June. A group of deep-purple Globemaster or Gladiator alliums is a real This yellow allium (Allium flavum) is a good eye-catcher, especially when planted with white choice for rock gardens or pink peonies, delphiniums or tall bearded iris. The white-flowering Mount Everest is a bit shorter and looks sharp in front of shrubs with deep-green or burgundy foliage or rising out of a groundcover of periwinkle (Vinca minor). Corkscrew allium: Drought-tolerant corkscrew allium (Allium senescens ssp. montanum var. glaucum) makes a good edging plant in the dry soil at the top of my stone retaining wall. Its blue-green leaves twist like loose corkscrews. Bloom time is late summer. Ozawa allium (Allium thunbergii 'Ozawa'): A tidy, clump-forming plant that grows 18″ to 20″ high. Among the last of the perennials to bloom, its flowers often don't open until late September or October. Bees love it. Another late-bloomer that flowers in autumn. Its pink flowers pair well with coreopsis, gaillardia, solidago and other fall flowers. Schubert allium (Allium schubertii): Quite dramatic, though only 8″ tall . Its foot-wide The drumstick allium is a bit floppy, so plant umbels look like an exploding pink fireworks it among other perennials that can provide display. Sure to elicit comments from garden visitors. Seed heads add interest for a month or support. more after blooms fade. Drumstick allium (Allium sphaerocephalon): Blooms in early July, a couple weeks after Purple Sensation. Not as erect and orderly as Purple Sensation, but in the right place (where casual is OK), the two-toned, burgundy-green heads are fantastic. Great with ornamental grasses. Yellow allium (Allium flavum): A midsummer- blooming favorite that is well-suited to rock gardens. Over a 10-day period, the cluster of florets slowly emerges and becomes an exuberant display of color. Related species available in yellow, pink and white, 12″ to 24″ high.

Plants That Climb All About Vines and Other Climbing Plants By Kathy LaLiberte Growing up rather than out is a good way to save space in the garden. You also get to enjoy lots of great vine plants such as sugar snap peas, pole beans, moonflowers, bougainvillea, and clematis. Adding a trellis or some other vertical structure to your garden also gives you a whole new dimension of visual interest. But figuring out how to match climbing plants with the right kind of support leaves many gardeners baffled. Why won't pole beans and tomatoes climb up a lattice frame? Why won't sweet peas and clematis climb a pole? The answer is that climbing plants climb in particular ways: some wrap, some adhere, and some curl. Here's how to recognize which plants Passionflowers use wiry tendrils that actually do what: reach around in the air until they come into contact with something they can grab. Tendrils: Peas are a good Examples example of a Stem tendrils: plant that uses Passionflower tendrils to (Passiflora) climb. Tendrils Grape (Vitis) are skinny, wiry structures Ampelopsis glandulosa along the Leaf tendrils: plant's stem Sweet peas (Lathyrus) that actually Cobaea scandens reach around in the air until Chilean glory flower they come into (Eccremocarpus scaber) contact with something they can grab. Once contact is made, the tendril curls, forming a coil that allows the plant to adjust 1 of 3 10/24/10 2:36 PM Plants That Climb, Climbing Plants, Trellises, Vines: Gardener'... http://www.gardeners.com/Plants-That-Climb/5373,default,pg.html the degree of tension or pull on the support. There are two kinds of tendrils. Stem tendrils (which passionflowers and grapes have) are shoots that grow out of the stem. Leaf tendrils (which peas have) look very similar, but the tendrils are actually modified leaves that emerge from a leaf node. Like a rock climber scaling the face of a mountain, plants that have tendrils need handholds in the form of horizontal supports. Netting works well for plants with tendrils, as long as the mesh is more than 2" square. I once tried growing sweet peas on some bird netting that we had lying around and the peas refused to take hold. Branches are a popular material for supporting tendril-climbers. Just make sure that branches are brushy—with lots of small side shoots—and not smooth, vertical sticks. Horizontal strings attached to posts or bamboo poles are ideal. Just don't position the strings more than about 4 inches apart or the newest set of tendrils may not be able to reach the next level of string. Also, because most tendrils are only about an inch long, they need to wrap around something thin (like string or wire) that's no more than about 1/4 inch in diameter. Twiners: Morning glories, pole beans, honeysuckle and clematis are some of the many plants that twine. There are Examples two important differences among twining plants: they either Twining leaves: have twining leaves or twining stems. Clematis Climbing nasturtium Plants with twining leaves, such as clematis, use their leaves (Tropaeolum polyphyllum) like tendrils. The young leaves of these plants are able to twist around slender wires, string, twigs or other leaves. The Rhodochiton key is to provide a thin enough support for the leaf stem to Twining stems curl around. A lattice made of 1-inch wide slats won't work for Pole beans leaf twiners.

  • Van Zyverden's
    Van Zyverden’s ALLIUM SPHAEROCEPHALON Allium are in the same family as garlic, onions, chives and shallots. This makes gardeners wonder if they should include them in their ornamental gardening plans, as it conjures up images of supermarket produce. But because good garden designs are often made up of different shapes, allium’s rounded blooms make for high drama and interest in the garden. The Allium group gets more popular annually, from over 300 species to choose. They amaze everyone, and few plants create this kind of wow in the garden. We will be adding many new varieties shortly. Each flower head displays an Commonly called rounded Deer and rodent resistant interesting bi-color effect as the florets headed leak or drumstick allium change from green to purple About This Variety: Allium sphaerocephalon is a bulbous perennial that is ornamentally grown for its early summer bloom of rose-purple to pink flower heads. This plant is native throughout Europe to the Caucusus, Iran and northern Africa. Cylindrical, hollow, grassy, gray-green leaves to 14” long form a foliage clump in spring. In late spring, sturdy slender flowering stems rise topped with egg-shaped flower heads. Each flower head is a tight, dense, clover-like cluster of tiny florets that emerge deep green but mature to rose-purple. Flower heads resemble the flower heads of some clovers. Flowers lack fragrance. Growing Instructions: As Alliums do not like wet feet, find a sunny location where the soil drains well or try to improve the drainage. The bulbs will rot in wet areas.

Conservationists are far from able to assist all species under threat, if only for lack of funding. This places a premium on priorities: how can we support the most species at the least cost? One way is to identify `biodiversity hotspots' where exceptional concentrations of endemic species are undergoing exceptional loss of habitat. As many as 44% of all species of vascular plants and 35% of all species in four vertebrate groups are con®ned to 25 hotspots comprising only 1.4% of the land surface of the Earth.

  • Q. I'd Like to Know If There Are Any Vines I Can Plant Soon That Could Be Blooming by Early June? Several Answers Are Below
    Q. I'd like to know if there are any vines I can plant soon that could be blooming by early June? Several answers are below. A. I would prefer either a clamantis vine or a morning glory. A. Morning glories may be your answer. BUT once you have them, you will always have them. They reseed like crazy!! A. Eccremocarpus scaber Flame Grow 10 to 15 feet in a season. Perrenial and will flower in the first season planted from seed. Blooms June to September. Evergreen perrenial. Flower is yellow orange and red A. You can "plant" almost any ANNUAL vine which might appeal to you (some listed below). HOWEVER, and this is very important as I know from experience the hard way, i.e. losing a vine in May to the dreaded water overload, i.e. rain or a late season cold snap. Here's how you want to do this: Find the annual vine you'd like to grow. Once you get it home from the garden center, transplant it into a 1/2 to 1 gallon sized container and grow it in there until about the 3rd week of May or when the temps are averaging about 65 to 70 degrees daily. Place a small trellis in the container so the vine can start climbing. Try keeping it out of the wind, but in good light from the sun (a small greenhouse atmosphere would be ideal). It will continue to grow in the container and may even throw off some flowers. Transplant when the conditions are right into a sunny area with a trellis for it to climb up (about 4 to 5 feet in height).

  • Grow Bloomin' Onions
    Grow Bloomin’ Onions By Ray Novitske, Fairfax Master Gardener Mention spring blooms, and most of us think of early crocus, daffodils and tulips. But there are other spring bulbs that are often overlooked because they bloom later in the season. Alliums, also called Flowering Onions, can take your spring flowering season from the end of the tulips into the early summer. Most bloom in late spring through June. University of Arkansas Research & Research Arkansas of University Alliums are members of the Amarylidaceae family, which includes amaryllis, leeks, scallions, leeks, Extension photo: photo: chives and of course, onions. There are about 600 Allium gigantium different species of alliums, and most of them are native to North America, with the remaining hundred or so occurring in China. A handful are also found in Europe, Africa and Asia. Alliums are fall-planted bulbs that produce a cluster of flowers on a sturdy stem, varying in height from a few inches to a few feet. They need full sun and average, well-drained soil, and have few problems. Deer and rodents leave them alone because of their onion taste. After blooming, the foliage eventually dies back like tulips and daffodils, leaving the dormant bulb underground until ready to produce a new bloom the following year. Alliums need a warm period after blooming to replenish the food in the bulb for the next year, in addition to a cold period during winter. They also do not survive well in poorly-drained soil — not needing frequent watering. Some consider them to be drought-tolerant. One of the best known alliums is the giant Allium giganteum, a University State Carolina North native of central Asia.
