Items

• Zinnia

  The composite inflorescences of Zinnia come in a variety of warm and cool colors, and may be single-, semi-double, or double-flowering.
• Zinnia

  Zinnias, not quite as popular as in times past, nevertheless are more compact and generally more mildew-resistant than their predecessor cultivars and series.
• Zinnia

  Leaves of Zinnia are opposite in arrangement and without petioles, clasping tightly to the stems. The foliage of many modern zinnias still develops some degree of powdery mildew by late Summer.
• Zinnia

  Zinnias are terrific annuals, but most succumb to the unsightliness of powdery mildew in late Summer.
• Narrowleaf Zinnia

  This white-flowering Zinnia has a loose, willowy, spreading habit in the garden. It is noted for two traits: its groundcover growth habit, and its resistance to powdery mildew.
• Japanese Zelkova

  This particular specimen of Japanese Zelkova is likely to be one of the cultivars noted for its burgandy fall color, even as a young tree.
• Japanese Zelkova

  The fall color of Japanese Zelkova depends in part on that particular autumn's overall quality, and in part on whether it is a cultivar. This specific tree is likely to be the species form, with its multicolored array of foliage in a mixture of hues.
• Japanese Zelkova

  Young trees of Japanese Zelkova best display the vase-shaped growth habit of this Elm Family member, and often become so densely twiggy that individual branchlets may need to be removed on a biennial basis to allow better air flow and sun penetration throughout the canopy.
• Japanese Zelkova

  The mature bark of Japanese Zelkova, while almost smooth, is slightly flaky and is a combination of gray, blue, green, cream, and orange colors, making the larger branches and trunk ornamental with age.
• Japanese Zelkova

  The zigzag and relatively thin twigs of Japanese Zelkova are accentuated in Winter by the alternate buds that emerge at distinct angles from the stems.
• Japanese Zelkova

  The leaves of Japanese Zelkova (elliptical, serrated, and alternate) often have outstanding fall color, and the heavily lenticeled branches develop into multicolored, flaky bark with age, both improvements as compared to American Elm, which this tree has sometimes replaced in modern landscapes.
• Japanese Zelkova

  Japanese Zelkova, a member of the Elm family and perhaps the best replacement for American Elm, has a vased growth habit and outstanding fall color, especially among its cultivars.
• Calla Lily

  Calla Lily is composed of many basal sagittate leaves and very attractive, funnelform flowers composed of a curled spathe and yellow spadix, all of which arise from the tender rhizomes underground. It is usually planted in partial shade in moist to permanently wet, organically-enriched soils.
• Florida Arrowroot

  <i>Zamia pumila</i>, the Cardboard Palm, is the only species of cycad native to the United States. Found growing on sandy soils in Florida, this cycad was used as a source of food starch by Native Americans. This image shows a female cone.
• Golden Sword Yucca

  'Golden Sword' has its broad yellow variegation down the middle of the radiating foliage, with green margins. Unfortunately, the variegation may revert back to green in certain sectors of the crown, and these regions should be removed during periodic inspection of the plant.
• Bright Edge Yucca

  'Bright Edge' has its yellow variegation on the margins of the spikey foliage, with normal green centers. Like other variegated cultivars of this species, the variegation may revert to green in certain sectors with age, and these should be removed before their more vigorous growth rate overtakes the rest of the plant.
• Adam's-needle Yucca

  The inflorescence of Yucca ranges from three to eight feet in height, with more than one stalk occuring on mature plants with wider crowns. Full sun is needed for optimum floral performance, composed of bell-like creamy flowers that open from bottom to top, and from inside to out, on the narrow pyramidal inflorescence in mid-Summer.
• Adam's-needle Yucca

  The green to blue-green foliage of Yucca gives this species its specific epithet, due to the thready \filaments\ that occur on its sharp leaf margins.
• Adam's-needle Yucca

  Ever tried to dig up an established Yucca with the purpose of its wholesale removal from the landscape? You will find that its thick fleshy roots go both horizontal and deep, that there are an amazing quantity of them, and that you will never remove all of them. When sprouts return, hit them immediately and repeatedly with a weed killer (or repeatedly cut them off) until all signs of life have disappeared. This will take months, if not a couple of years.
• Adam's-needle Yucca

  After flowering, the tall and woody stalks of Yucca should be cut back to promote tidyness of the plant.
• Texas Purple Japanese Wisteria

  When buying Wisteria, always purchase named cultivars (which will have large, fragrant inflorescences of a specific color).
• White Japanese Wisteria

  With great effort, Japanese Wisteria can be trained and maintained in tree form, whereby its stunning display of Spring inflorescences is at its greatest appeal.
• Wisteria

  Once established, Wisteria may easily grow eight to ten feet a year, and even more if it has been severely pruned back. However, the flowering stems tend to be much shorter, and may be left on the vine if selective pruning of long vegetative stems is performed.
• Wisteria

  Wisteria is notorious, if given the opportunity to twine upon a narrow supportive structure (a wire in this case), of twisting upon its own self. Fortunately, instead of girdling and strangling itself, this vine usually self-grafts along the numerous points of contact, and forms solid branches and trunks at these junctures.
• Wisteria

  The fruits of Wisteria are an easy indicator of its membership in the Bean Family.
