Washington Hawthorn Crataegus phaenopyrum (25') Four seasons of interest are present with this plant. White flowers grace the early spring. Attractive dark green foliage adorns the summer. Reddish fall color enhances the autumn and red-orange fruit decorates the holiday season. This plant is heavily armed and thorns may limit this plant's use in urban areas. Its attractiveness to birds is due to the fruit and the dense branching pattern. Washington hawthorns can be grown either single-stemmed or multistemmed and tolerate very high light. A cultivar 'Vaughn' is very salt-tolerant and might be highly desirable in areas where deicing salts are a problem. Service life is 25 years with proper pruning. |
Flowering Crabapples Malus sp. (10-25') A wide variety of growth habits are present, but the tree is typically as broad as tall. Flowers range in color from white to pink and red. Disease-resistant cultivars tend to be white, but some pink selections are available. Fruit color ranges from red through orange to yellow and green. Crabapples as a group are very stress-tolerant and will grow in full sun to very light shade. Service life is 30-plus years. Some disease-resistant cultivars with their flower and fruit colors are as follows: Adams: pink flowers, red fruit; Beverly: white flowers, red fruit; Bob White: white flowers, yellow fruit; Coralbust: pink flowers, very little fruit; David: white flowers, red fruit; Donald Wyman: white flowers, red fruit; Floribunda: pink flowers, red and yellow fruit; Indian Magic: pink flowers, red fruit; Indian Summer: pink flowers, red fruit; Liset: pink to red flowers, crimson fruit; Ormiston Roy: white flowers, orange fruit; Mary Potter: white flowers, red fruit; Sargentii: white flowers, red fruit; Winter Gold: white flowers, yellow fruit; Candied Apple: pink flowers, red fruit and a weeping habit. |
Green Hawthorn Crataegus viridis (25') This hawthorn is vase-shaped, which is unusual in the hawthorns. This habit allows for foot traffic beneath the crown. The plant is less heavily armed than the Washington hawthorn. The white flowers are followed by red fruit that persist until early spring the following year. Fruit is very attractive to birds such as robins and cedar waxwings. Fall color is yellowish and more attractive than most hawthorns. Rust is a cosmetic problem with this plant. High prevailing winds tend to windthrow hawthorns in general. Service life is 25 years. |
Flowering Cherry & Plum Prunus sp. (25') Growth patterns vary somewhat by species. Flower color ranges from white to pink. Fall color is usually not spectacular. Purple summer foliage color is available in the Purple-leaved plum. (Prunus cerasifera) The cultivars 'Thundercloud' and 'Newport' are the best. A weeping habit of growth is present and extremely attractive in the Weeping Higan Cherry (Prunus subhirtella 'pendula'). Okame, an attractive upright oval cherry with pink flowers, is cold-hardy. Service life ranges from 15 to 30 years, depending on the species. |
