Abstract: An ornamental, flowering shrub of the genus Potentilla fruticosa, having as its most important novel characteristic the ability to produce flowers which are red in color, a color not heretofore known in this genus. The seasonal development pattern of the new plant is later than that of other Potentilla varieties; both new leaves and flowers appear later in the spring than on other Potentilla, and last longer in the fall; however, very dry weather conditions cause red flowers to fade to a reddish-yellow, but the same flower becomes red again after rain. Another distinguishing characteristic is the foliage, which is a brighter green than in other Potentilla; and grows with more density, and more dwarf size than the seedling relatives.
Abstract: An ornamental, flowering shrub of the genus Potentilla fruticosa, having as its more important novel characteristic the ability to produce flowers which vary from pink to red in color, a color not heretofore known in this genus. (RHS Color Chart Red Group 53C to 48C). Fading occurs as in related Potentillas, but to a pale pink color, but this is believed to be reduced by partial shade and increased by very wet or very hot, dry conditions. The plant is more dwarf than its parent. Present size of parent plant is 40 cm. high, 85 cm. maximum diameter (at age of 31/2 years).
Abstract: A new and distinct variety of Bougainvillea vine (popularly known by the same name). A chance seedling selection of a plant with a combination of superior qualities of (1) large flower bracts; (2) vibrant purple colored bracts; (3) deeper and more colorful purple pubescent new growth.
Abstract: A new and distinct variety of Pinus thunbergiana tree (popularly known as Japanese black pine). A specifically selected, genetically superior plant which is able to absorb more iron from the soil than other seedlings of Pinus thunbergiana resulting in a more uniform green color of the needles. Another distinguishing characteristic of this selection is the absence of needle tip burn (or browning) associated with smog.
