o Dove Tree
o Cornaceae  (dogwood family)                                                                                                                    o USDA Hardiness Zone 6-8                                                                                                                           o 20-40 ft spread- 20-40 ft                                                                                                                              o  broad pyramidal habit

o soil requirements-organically rich, consistently moist, well-drained soils in full sun to part shade                                                                                                                                                               o leaf arrangement- Toothed, broad oval, red-stalked, bright green leaves (3-6” long) are heart-shaped at the base. Back of leaf covered in wax- helps slow loss of moisture
o fall colour- dull pastels to bright oranges and reds
o flower/cone/fruitdescription(s)-  Red-anthered flowers in rounded clusters bloom in April-May. However the showy parts of the bloom are the large oval-rounded showy white involucre bracts (one 3-4 inches long and the other 6-7 inches long) which subtend each flower cluster. The bracts flutter in the slightest breeze, and, from a distance, purportedly look like white doves sitting in the tree, hence the common name. Flowers are followed by round, greenish-brown, golf ball-sized fruits on 2-3” stems                                                                  o limitations-
o suitable uses-Specimen landscape tree. In full flower, this tree produces a spectacular bloom. Street and park planting in BC.

o Ginkgo
o Ginkgoaceae                                                                                                                                                  o USDA Hardiness Zone 3-8                                                                                                                           o 50-80 ft spread- 30-40 feet                                                                                                                      o  tall, somewhat sprawling and awkward, quirky
o water- medium
o soil requirements- average, medium moisture soil in full sun. Prefers moist, sandy, well-drained soils. Tolerant of a wide range of soil conditions, including both alkaline and acidic soils and compacted soils.                                                                                                                            o leaf arrangement- two-lobed, somewhat leathery, fan-shaped, rich green leaves with diverging (almost parallel) veins. Long shoot, short shoot morphology.
o fall colour- bright yellow leaves
o flower/cone/fruitdescription(s)-  Nurseries typically sell only male trees (fruitless), because female trees produce seeds encased in fleshy, fruit-like coverings which, at maturity in autumn, are messy and emit a noxious, foul odor upon falling to the ground and splitting open.                  o limitations-Female fruit smells bad
o suitable uses-street tree, specimen tree. tolerant of saline conditions, air pollution and heat. Adapts well to most urban environments.

o water- dry to medium
o soil requirements- average, dry to medium, well-drained soil in full sun. Adapts to a wide range of soils. Tolerates drought and many city air pollutants.                                                               o leaf arrangement- pinnate or bipinnate, feathery, compound leaves (to 18″ long), each leaf having 7-17 irregularly lobed leaflets
o fall colour- pinkish bronze to purplish in spring, mature to a bright green in summer and turn yellow (quality variable) in fall
o flower/cone/fruitdescription(s)-  Bright yellow flowers (1/2″ wide) appear in early summer in long, terminal, panicles (12-15″). Falling blossoms may or may not resemble “golden rain”, but the fallen blossoms often form an attractive golden carpet under the tree. Flowers give way to interesting, brown, papery seed capsules which somewhat resemble Chinese lanterns.
o suitable uses-Small shade tree, street tree, lawns or terraces.

o water-medium
o soil requirements- moist, acidic, humusy, well-drained soils in full sun                                             o leaf arrangement- serrate compound-pinnate leaves
o fall colour- red leaf, yellow fruit
o flower/cone/fruitdescription(s)-  Dense flattened clusters (corymbs to 3-6” across) of very small 5-petaled white flowers (each to 1/4” wide) appear in May. Flowers are followed by bright orange-red berries (each to 5/16” diameter) that ripen in late summer and remain on the tree after leaf-drop. Berries are attractive to birds and animals, but too acidic to be eaten fresh off the tree by humans.                                                                                                                                      o limitations-not drought tolerant, flowers smell like old fish

o fall colour- yellow-red, insignificant
o flower/cone/fruitdescription(s)-  It is noted for its pendulous clusters of bell-shaped, mildly fragrant, 5-petaled, waxy white flowers (each to 3/4” diameter) that bloom in May-June. Drooping flower clusters are easily visible because of the upward posture of the foliage.

o suitable uses-Small landscape tree for lawns or patio areas.
