Drake Elm (Ulmus parvifolia 'Drake')

'Drake' is a Chinese elm (Ulmus parvifolia) cultivar widely planted in the southern United States, particularly in California, Texas, the Gulf states, and Florida. It is distinguished from other Chinese elm cultivars by its distinctly weeping or cascading form and is among the most commonly planted resistant elms in warm-climate landscapes.

Origin

'Drake' originated in California in the mid-20th century; the precise breeder and introduction date are not consistently documented in the horticultural literature, with sources placing the cultivar's origin variously in the 1950s and 1960s. The cultivar has been continuously available through California and southern US nursery networks for several decades.

Like all Ulmus parvifolia selections, 'Drake' inherits the natural DED resistance characteristic of the species.

Identification

  • Form: Distinctly weeping or cascading — branches arch outward and droop, producing an umbrella-like silhouette at maturity
  • Mature size: 30–40 feet tall, 30–50 foot crown spread
  • Leaves: Small (1–2 inches), oval, single-serrated, dark glossy green; semi-evergreen to evergreen in mild climates
  • Bark: Mottled exfoliating lacebark in patches of gray, green, orange, and brown
  • Fall color: Yellow to reddish in cooler climates; muted or absent in warm climates where leaves persist
  • Growth rate: Fast

Hardiness and adaptability

  • USDA hardiness zones: 6–10
  • Site preferences: Strongly preferred warm-climate sites; tolerates drought, heat, and a wide pH range
  • Stress tolerance: Among the most heat- and drought-tolerant elm cultivars; well-adapted to coastal and Mediterranean climates

Dutch Elm Disease resistance

'Drake' demonstrates high natural DED resistance characteristic of Chinese elm. The cultivar has been planted in DED-affected regions for decades with minimal recorded DED mortality.

The cultivar is also resistant to elm yellows phytoplasma.

Landscape uses

  • Street trees in southern US cities — particularly in California, Arizona, Texas, and Florida
  • Park and residential plantings in warm climates
  • Specimen plantings where the weeping form is featured
  • Plantings around pools and water features (the cascading form fits these contexts well)

Limitations

  • Cold-hardiness limited to zone 6 minimum; not suitable for northern US plantings
  • Weeping form is distinctly different from classic upright elm silhouettes; not appropriate where a traditional canopy is desired
  • Litter from heavy seed production in fall
  • Sometimes confused at retail with Siberian elm (U. pumila); verify cultivar identity using the mottled exfoliating bark, which Siberian elm lacks
