Medium Tree Species

Rounded to broad rounded, lustrous dark green leaves.  Deep red colored flowers arranged on upright panicles in June-July.

A seedling of ‘Crimson King.’  Spring foliage color is reddish-purple.  Foliage turns bronze as the season progresses.  Growth habit is oval at maturity.  Seeds are samaras maturing in the fall. Tolerant of air pollution.

Rounded canopy with lustrous leathery dark green foliage.  Snow white groups of tiny flowers in May.  Handsome gray-brown bark may exfoliate in papery curls.  Birds relish soft ½” diameter blue fruit only on female plants.  No way to know whether tree is male or female until maturity.

Growth habit is vase-shaped.  Fall foliage can be burgundy colored.  Elms are durable trees that cope well with low soil oxygen conditions characteristic of many urban sites.  This cultivar was introduced by the United States Department of Agriculture and is a cross between Ulmus carpinifolia and Ulmus parvifolia.

One of the original trees planted by the city’s first settlers.  Very tolerant of harsh growing conditions, including alkaline soils, heat, cold and air pollution.  Roots can be shallow particularly where water is applied superficially.  Lustrous dark green leaves are 2-7 inches long and up to 6 inches wide.  Less water demanding at maturity.

 This tough tree copes better than many species with wide-ranging and difficult urban conditions.  Long upright panicles of yellow blossoms appear in July giving rise to papery capsules that enclose black, hard-coated seeds.  Round canopy is produced by irregular branching habit which is wonderfully unique to each tree.  Less water demanding at maturity.

Growth habit is oval to rounded.  Small diameter twigs can be pendulous giving a graceful appearance.  Bark is mottled exposing patches of color giving rise to the name Lacebark.  Best growth in moist soils.  Leaves 1 to 2 1/2 inches long and about half as wide.

Dense oval crown.  Green foliage turning yellow in the fall.  Tolerates drought as well as excessive moisture.  One-winged seed.

Light green leaves emerge early in spring.  Fragrant white drooping flower clusters that are 4 to 6-inches long appear in May.  This tree is also known as Birdcherry for the birds that feed on its ¼ inch black berries ripening in July and August.  Canopy is round in appearance with branches arising low on the trunk.

Very attractive dark rose-pink flower clusters borne in late May or June.  Leaves are pinnately compound with leaflets similar to but larger than Honeylocust.  Twigs have short thorns.  Tree extracts nitrogen from the air, can grow 2 feet per year, is adaptable to urban stress and arid climates.

Male non-seed bearing tree with better branching structure and slower growth than is characteristic of the species.  This cultivar can produce sensational red and orange colors in the fall when conditions are favorable.  This is a species that does well where other trees fail to thrive.  Less water demanding at maturity.

Leaves are pinnately compound, generally with 7 to 9 leaflets.  Yellow fall color.  Bark of mature tree resembles beech.  White fragrant flowers are borne on 8 to 14-inch long pendulous panicles in May-June.  Fall pods are 2 to 4-inches long and ripen in October.  Beautiful tree well-suited to medium size yards.
