Need suggestions for trees and shrubs and perennials shade garden in Kingsway


Hello, am trying to replace old shade garden under large Oak Trees and would like some suggestions as to what to plant.
Specifically, thinking of adding five cedar/type evergreens that will grow to 6-8 feet.
Plus some flowering large bushes and or more evergreen bushes.
Back of lot is about 45-50 feet wide by 4-6 feet deep.
Very shaded due to neighbours trees as well, and soil is not sure?


Thank you for contacting the Toronto Master Gardeners.

The bane of the shade garden and shade gardener is dry shade, usually caused by competition from nearby trees. The fine roots of your established oak tree compete for the moisture and nutrients in the soil at the expense of newly planted plants. Before planting, loosen the existing top soil with a garden fork and add a layer of compost, thereby increasing the soil’s water retention. Be careful not to raise the grade above the tree roots more than 10cm, this may compromise the health of your tree. Every fall I would continue to improve the texture and quality of the soil by loosening the topsoil and adding in at least 15cm of shredded leaves along with 2.5cm of compost.

Here is a list of some evergreens for you to consider:

Hinoki Cypress (Chamaecyparis obtusa ‘Nana Gracilis’): this evergreen grows in full sun to part shade. This is a slow growing conical evergreen which will reach 6-9′ at maturity.

Yews (Taxus spp.) Yews come in many sizes and shapes. Unlike cedars which do best in full sun and moist soil, once established yews can handle partial shade and some varieties such as Upright Japanese Yew (T. cuspidata ‘Morden Upright’), Dwarf Japanese Yew (Taxus cuspidata ‘ Nana’) , Globe Japanese Yew (Taxus cuspidata ‘Clipped Globe’) and Taxus x media ‘Runyan’ can grow in full shade. The above yews come in many shapes: pyramidal shapes, columnar shape, global and spreading and sizes Before you make your choice make sure to check the mature height and spread.

Jeddeloh Dwarf Hemlock (Tsuga canadensis ‘Jeddeloh’): Grows best in medium moisture, well-drained soils in part shade to full shade. This plant grows as a dwarf, flat-topped, spreading mound with a distinctive funnelform center depression that resembles a bird’s nest. mature height is 2-3′ and 3-4′ wide.

Dogwood (Cornus spp.) Cornus is a genus of about 30–60 species of woody plants which grow in full sun to part shade and are tolerant of a wide range of soil conditions. Their colourful branches add winter interest to the landscape.

Japanese Pieris (Pieris sp.): These shrubs grow and flower best when planted in full sun or partial shade. They will grow in deep shade, but generally do not flower as well, and the new foliage growth is usually not as brilliant.

Oregon Grape (Mahonia aquifolium): Is a broadleaf evergreen shrub with shiny holly-like leaflets

Dwarf Highbush Cranberry (Viburnum trilobum ‘Compactum’): is a rounded shrub with dark green foliage which turns red in the fall along with red berries in October. Does best in full sun to part shade.

Common Snowberry (Symphoricarpos albus) Grow in average, medium moisture, well-drained soils in full sun to part shade. Best fruit production occurs in full sun.

Some perennials to consider planting are: Barrenwort (Epimedium spp.), Wild ginger (Asarum canadense) is a great native ground cover, Lenten Rose (Helleborus spp.), Siberian bugloss (Brunnera sp.). Garden Making has an excellent article  on Planting in Dry and Shady Gardens There are also a number of native perennials that can tolerate or even thrive in dry shade. This link provides quite a comprehensive list.
