  • Publication number: 20200008369
    Abstract: A horticultural apparatus is provided for managing soil conditions. The horticultural apparatus includes a nonporous and translucent polymeric sheet forming a two-dimensional array of basins defining an upper plane and a lower plane. Each basin has a rim in the upper plane, a base in the lower plane, sidewalls that slope inwardly from the rim to the base, and a hole in the base. The polymeric sheet connects the rim of each basin to the rims of each adjacent basin to form a continuous canopy between the basins. The continuous canopy preferably prevents air convection through the polymeric sheet when the hole in each basin is pressed against the soil. Embodiments of the horticultural apparatus may be used to warm the soil, control weed growth, control water run-off and extend the life of an organic mulch.

  • Publication number: 20120324609
    Abstract: A variety of sugar maple, Acer saccharum, subspecies, Caddo, named ‘WHIT XLV’, is characterized by an upright and oval growth habit at the age of 16 years, but is expected to develop a more rounded crown with age and may reach a height of 30 feet with a 25 foot spread. Leaves emerge medium green and quickly change to very dark glossy green. When adequate spring moisture is present, all leaves on the flush of growth develop full size. However, when spring moisture becomes limiting before all leaves on the twig are produced, the younger leaves will become progressively smaller in size yet the same shape and dark green color. No flowers have been produced on this tree by age 16 years. Fall color develops late in the fall after various species of trees have developed fall color and most of the leaves have fallen.

  • Patent number: PP23559
    Abstract: A new and distinct variety of crapemyrtle, Lagerstroemia indica, particularly distinguished by having a much branched, near globular growth habit, and a near constant show of sterile, ruby red flowers from bright crimson flower buds during the growing season. Because the plant is sterile, old flowers stay showy longer, and new flower buds form in the same positions as flowers that age and fall away. Inflorescences are only between 1.5 and 6 inches long but are produced in great numbers across the outer surface of the network of branches.

  • Patent number: PP27085
    Abstract: A new and distinct variety of crapemyrtle, Lagerstroemia indica, particularly distinguished by having a much branched upright growth habit, a near constant show of sterile, cardinal red flowers from bright crimson flower buds during the warm growing season, with lighter red flowers during rainy periods or cooler fall conditions. Because the plant is sterile, old flowers stay showy longer and new flower buds form in the same positions as flowers that age and fall away. Inflorescences are short around the base of the plant, but are 12 to 14 inches long and 6 to 12 inches wide in the upper parts of the plant. The plant is highly resistant to both powdery mildew and Cercospora leaf spot under north central Oklahoma conditions.

  • Patent number: PP31873
    Abstract: A new and distinct variety of Lagerstroemia indica, commonly known as crapemyrtle, named ‘Whit XI’, particularly distinguished by having a unique complex of highly modified sepals on a network of large, loose panicle-like structures. The plant does not produce flowers. The leaves are simple, alternate with a smooth margin, typical of the species. Young leaves emerge slightly crimson-green, maturing to dark green. Inflorescences are comprised of a network of irregular stem structures terminating in highly modified panicles with highly modified sepals, at first light purple in color, darkening with age to a darker purple and finally to brown. The inflorescences grow in a network over the surface of the plant and appear and function somewhat like normal flowers. As the modified sepals age they turn brown, but at the same time the panicle continues to grow slowly, producing new sepals light purple in color, which continues the appearance of flowering.

  • Patent number: PP33515
    Abstract: A new and distinct Heptacodium miconioides, Fall Festival Tree aka Seven Sons Flower, designated cultivar ‘Whit LXXXI’ providing year round interest in the landscape. The color begins with early emergence of dark green leaves, followed by a floral show of flowers in late summer or early fall, large concentrations of fragrant white flowers, then after flowers fall, sepals elongate from barely visible to ? to ? inch and turn crimson creating a second flower-like show in the landscape then after the sepal show is stopped and leaves drop due to frost, the outer bark sloughs off revealing white bark that remains a color show in the landscape until early spring when leaves emerge again. ‘Whit LXXXI’ is cold hardy to ?30 F., but also does well where little or no frost occurs, roughly zones 4 through 9. Free of disease or insect problems.

  • Patent number: PP35912
    Abstract: The new and distinct variety of river birch tree, Betula nigra, which was given the cultivar name ‘Whit XXVI’, is characterized as having a tree form that is broadly pyramidal to oval and may grow with a single or multiple stems for greater landscape appeal. The bark of the ‘Whit XXVI’ is distinctly orange during late summer after the greatest stem diameter increase and remains so throughout the winter with only moderate darkening, but remaining orange in color. Bark coloration begins at about one inch diameter and remains. The leaves of ‘Whit XXVI’ are dark green and slightly smaller in size and more plentiful than a typical river birch seedling. In one example, ‘Whit XXVI’ averaged about 1.15 leaves per inch of twig while the typical river birch seedling averaged about 0.7 leaves per inch of twig.
