Landscaping Mississauga gardens – drought tolerant shrubs – Devil’s Walkingstick

Devil's walkingstick

Devil’s Walkingstick is an example of a larger shrub that does well in all soil conditions

Devil’s Walkingstick (Aralia spinosa), is a large deciduous shrub native to eastern North America, also known as Hercule’s club, or Mississippi hoe handle. The various names refer to its unusual look – the stems of the plant are unbranched and simple, like a walking stick, and they are covered with large prickly thorns that would metaphorically be associated with the devil.

The shrubs generally grow in clusters of unbranched stems, rising to the height of 3.5–6 m which bear upon their summits a crowded cluster of doubly or triply compound leaves, thus giving to each stem a peculiar tropical palm-like appearance.

The shrub is particularly attractive in the autumn when its large green leaves turn to a distinctive shade of bronze red touched with yellow. In late summer the shrub is covered with individually small, but produced in large showy panicles, creamy-white flowers that smell like lemon. The fruit are purplish-black berries ripening in the late fall. An additional advantage of using devil’s walkingstick is the fact that they can easily be propagated from seed, by division, or from root cuttings, so you can only purchase one specimen and propagate for the rest of the garden.

The textural quality of this eastern native’s stems and foliage is superb. During winter, a circle of the thorn-covered stems lend strong winter

interest looking as magical as an outdoor sculpture. Dark blue-green compound leaves offer a tropical effect before turning yellow and purple in autumn. One-foot-wide flower clusters sit atop the foliage in summer and transform into purple-black fruits that attract birds

Landscaping Mississauga Gardens – Best trees for dry conditions: Honey locust, Turkish hazel & Russian olive

Honey locust

A great choice if you want a hassle-free, attractive, fast-growing (18”+ annually) ornamental tree that won’t shade out your lawn and landscaping as it has small leaflets that produce a filtered shade.

This native to central North America, deciduous tree requires very little maintenance once planted and established. In fact, it performs best if not fertilized or watered, since optimal growth conditions in the summer and rapid growth may increases susceptibility to winter dieback of some of the new branches.

Honey locust can reach a height of 20–30 m (66–100 ft). Its leaves are bright green in spring and turn yellow in the fall. The leaves are small and in the fall they simply disappear into the lawn and decompose, without any need for raking. The strongly scented cream-colored flowers appear in clusters by late spring. The name of this tree derives from the sweet taste of its fruit, flat legume pulp that matures in early autumn. The pulp is used for food by Native American people, and it can also be fermented to make beer. The long pods, which eventually dry and ripen to brown or maroon, make a striking visual statement against the winter snow.

This ornamental tree is your best choice in dry areas, where few other trees can survive and prosper and it also tolerates urban conditions, compacted soil, road salt, alkaline soil, heat and drought. The fast growth rate and tolerance of poor site conditions make it valued in areas where shade is wanted quickly.

Russian olive

Russian olive, commonly called silver berry, oleaster or Persian olive is a native to the western and central Asia, an area stretching from southern Russia and Kazakhstan to Turkey and Iran, which is becoming very popular in Ontario as introduced species.

Russian olive can be grown either as a large thorny shrub if you trim it regularly or it can grow to the size of a small tree up to 5 metres in height. This drought-resistant ornamental plant is a very attractive addition to any garden with its dense covering of silvery to rusty leaves and highly scented flowers that appear in early spring and are followed by clusters of small cherry-like orange-red fruit covered in silvery scales. The fruits are edible, and in Iran, the dried power of Russian olive fruits mixed with milk is used to treat rheumatoid arthritis and joint pains.

Russian olive needs to be planted with caution. Because it thrives in very poor soil conditions, has low seeding mortality and matures in a few years it often outcompetes the other plants and can become invasive.
