GROWTH HABIT
The Ulmus parvifolia 'Drake', or Drake Chinese Elm, exhibits an upright growth habit when young, maturing into a graceful, broad, spreading canopy that is typically rounded or vase-shaped, often with weeping or arching branches. This fast-growing, semi-evergreen tree (deciduous in colder climates) typically reaches a mature height of 35 to 50 feet with a wide spread of 40 to 70 feet. Its fine-textured foliage forms a dense canopy, complementing the ornamental, mottled bark in shades of gray, green, orange, and brown that becomes prominent as the tree matures.

SOIL TYPE
The Ulmus parvifolia 'Drake' is highly adaptable and not restricted to one specific soil type; rather, it thrives in a wide range of soil conditions, including sand, loam, and clay, as long as the soil is well-drained. It performs best in moist, fertile soils with a neutral to slightly acidic pH, but it tolerates both acidic and alkaline conditions and is remarkably tough in urban environments with poor or compacted soils. The crucial requirement across all soil textures is good drainage to prevent root rot, as the tree is also highly drought-tolerant once established.
MAINTENACE TIPS
Maintenance for the 'Drake' elm is relatively low once established, as the tree is drought-tolerant and resistant to most pests and diseases, including Dutch elm disease. During its establishment period, usually the first few years, provide deep, infrequent watering to encourage the development of a strong, deep root system. Annually in early spring, apply a balanced, slow-release fertilizer to provide essential nutrients for healthy growth. Monitor for common pests like aphids and caterpillars, addressing any issues promptly.

LEAF SHAPE
The leaves of the Ulmus parvifolia 'Drake', commonly known as the Drake Chinese Elm, are scientifically classified as a simple leaf type with an alternate arrangement along the stems. These small, leathery leaves typically measure 1 to 2.5 inches in length and feature an elliptical, ovate, or obovate shape with a characteristically asymmetrical or oblique base. The leaf margins are sharply serrated or doubly-toothed, while the surfaces are notably glossy and dark green on top with a paler, sometimes pubescent underside. Depending on the climate, this cultivar is semi-evergreen to deciduous, often transitioning to a vibrant yellow or reddish-purple hue in the fall.

FLOWER CHARACTERISTICS
The scientific name for the 'Drake' elm is Ulmus parvifolia 'Drake', and its flowers are botanically classified as perfect (possessing both male and female parts) and wind-pollinated. The flowers are insignificant and very small, typically appearing in late summer or early fall in inconspicuous clusters in the leaf axils. They are generally described as reddish-green, light green, or pale yellow, with red anthers that may stand out, but overall they lack ornamental showiness. These flowers rapidly give way to single-seeded, wafer-like, winged fruits known as samaras that mature in the fall.
FRUIT/SEED
The Ulmus parvifolia 'Drake' produces small, inconspicuous, greenish-yellow flowers in late summer, which develop into a single-seeded, wafer-like samara fruit. The samara is a flattened, papery, oval to elliptic-ovate dry fruit, typically about 1/2 inch (1 cm) long and brown when mature, with a distinct notch at the tip. The tiny seed body is located in the center of this encircling wing, and the fruits mature and drop in the fall. While the species Ulmus parvifolia can be weedy due to self-seeding, some 'Drake' specimens and other cultivars are propagated by cuttings or grafts, with some sources noting the flowers and seed pods are "inconspicuous" or that the fruit does not create a litter problem.

POLLINATORS
The Ulmus parvifolia 'Drake' (Drake Chinese Elm) primarily attracts birds and various insects, which are drawn to the tree for different reasons, although specific long-term wildlife food sources are limited. Songbirds are attracted to the insects that inhabit the tree's branches and leaves, using the tree for shelter and potential nesting sites. While the tree produces small, inconspicuous flowers in the fall and wind-dispersed samara fruits, these fruits are generally not a significant food source for most wildlife. However, observations have noted that bees, including honeybees, will sometimes visit the flowers, likely for pollen or nectar, especially when other sources are scarce in the late season. Butterflies have also been noted as being attracted to the general species, possibly as a host plant for some larvae, further contributing to the tree's modest role in supporting local biodiversity. The tree's primary wildlife value is therefore derived from the habitat and food it provides for general insects, which in turn support insectivorous birds.
PRUNING TIPS
Pruning should be performed during the dormant season in late winter or early spring before new growth begins. The primary goal is to establish a strong, single central leader when the tree is young and to develop good branch structure to prevent wind damage later. For mature trees, light, occasional thinning is usually sufficient to maintain its attractive, naturally weeping or vase-shaped canopy and to remove any dead, damaged, or crossing branches. Avoid topping the tree, and for best results, make sure all cuts are clean and made back to a main branch or the trunk.
