Sugar Tyme® Crabapple grows to about 10 feet, with a wide-spreading form. Pink buds open to huge, blindingly-snow-white blossoms, followed by glossy red, winter-persistent apples. Most growers claim this variety grows to 18 feet, but I think these photos shed more light on Sugar Tyme's growth habits. I will continue to monitor these trees for size in the years to come, but  these trees are not even 10 feet tall at 25 years.

Cultural Requirements: Plant in full sun for best flowering and fruiting. Prefers well-drained, slightly moist, and acidic to neutral soils. Once mature, crabapples tolerate drought conditions, but benefit with a 3-4-inch layer of organic mulch. Disease resistance: apple-scab: excellent; fire blight: good; cedar-rust: good; powdery mildew: good [3].

Crabapples are the most versatile of spring flowering trees for Midwest landscapes and are a great choice for the home garden. Many of them are small in stature and can maintain visual interest throughout the changing seasons with spring flowers, fall fruit, textured bark and craggy branches in winter.

There are about 55 different species in the genus Malus, and there are innumerable cultivars available in the landscape trade. The Arboretum's Crabapple Collection was started in 1924. Part of this collection on the West Side participated in the National Crabapple Evaluation Program which evaluated new and disease-resistant varieties. As a result of the multi-year evaluation and additions, it has transformed into the West Side Malus collection which now contains 60 different kinds and over 140 specimens with highly desirable qualities [1].

Sugar Tyme™ Crabapple's snow-white flowers
Crabapples are versatile, small, ornamental trees used in the urban landscape. Crabapples bloom in spring, usually in May, bearing flowers that vary a great deal in color, size, fragrance, and visual appeal. It is common for flower buds to be red, opening to pink or white flowers. The fruit ripens between July and November, and varies in size from ¼”to 2” long or wide. Crabapples thrive in full sun and grow best in well drained, slightly acidic soils (pH 5.5-6.5); however, they will grow well in many soil types. Most crabapple selections tolerate the cold winters and hot, dry summers prevalent in the Midwest.

For many years, crabapple cultivars have been selected on the basis of their flowers, but with some cultivars, undesirable features, such as disease problems and early fruit drop, outweigh their short-lived spring beauty. No single cultivar can fulfill every landscaping need [3].
