Ilex verticillata 'Winter Red'.
Species or cultivar Fall and winter interest
Alnus incana ssp. rugosa Large shrub without much interest, but early blooming. Its long catkins add a touch of soft green to dull early springtime gardens. Marescent leaves and fruit. For poorly drained corners.
Amelanchier spp. Large indigenous shrub or small tree with abundant white flowers, edible blue berries resembling blueberries, showy fall colours and decorative streaked bark.
Aralia elata Few large upright prickly branches. Known as “Devil’s walking stick.” Very large compound leaves, tropical looking, can reach 45 cm. Late blooming, flowers quite spectacular in compound umbels.
Aronia melanocarpa Indigenous shrub with lovely dark glossy foliage, persistent black fruit and showy fall colours. Attractive in bloom. Under-used.
Aronia arbutifolia Similar shrub to the previous one, but with small red fruit.
Aronia prunifolia Intermediate shrub, between the two previous ones, with small purple fruit.
Berberis thunbergii and cv Japanese or Thunberg’s barberry has bright yellow flowers and clusters of persistent red fruit, as well as lovely fall colours. Spiny, however. Previously banned, many cultivars with green, yellow and purple foliage are now available.
Betula nigra FOX VALLEY™ ('Little King') Peeling salmon-coloured bark. Compact shrubby version of the black birch. Unusual.
Buxus spp. and cv Shrubs with small round, persistent leaves. Tolerate pruning well. Often used for low hedges and topiary.
Calluna vulgaris Late blooming toward the end of summer. Several cultivars with colourful foliage in winter.
Celastrus scandens Climber. Persistent orange and yellow fruit on female specimens.
Clematis tangutica Climbing plant with yellow flowers in August. Round feathery fruit, persistent in winter.
Cornus sericea Indigenous shrub, interesting for its red shoots in winter. Use in mass plantings. An essential part of any winter garden.
Cornus sericea 'Isanti' Purplish-red shoots. Compact habit.
Cornus sericea var. flaviramea Yellow shoots.
Cornus sericea 'Cardinal' Flamboyant orange-red shoots.
Cornus alba var. sibirica Coral-red shoots.
Cornus alba 'Kesselringeri' Dark red-purple shoots, almost black. For a novel touch.
Cornus alba 'Siberian Pearls' Lovely burgundy fall colour. Dark red shoots.
Cornus sericea 'Bud's Yellow' Brilliant yellow shoots. Less subject to canker than C. sericea var. flaviramea.
Cornus alba 'Elegantissima' Red shoots and pale green leaves with cream margins turning a pinkish hue in the fall. A Quebec horticultural classic.
Cornus alba IVORY HALO® Similar to the previous one but with a more compact habit.
Cornus alba 'Alleman's Compact' Dark red shoots. Compact habit. Disease resistant.
Cornus mas Another dogwood (Cornelian cherry), but with very early small yellow flowers before the leaves open and with tart, edible red berries. No red shoots here.
Cornus racemosa Another dogwood, with white fruit and contrasting red pedicels. No red shoots on this one either.
Corylus avellana 'Contorta' Hazel with corkscrew branches. Very early blooming catkin flowers.
Dirca palustris Very early yellow flowers before the leaves open. Unusual silhouette. Small compact tree, known as leatherwood because its flexible stems can literally be tied in knots.
Erica carnea Heather, or heath, is a spreading plant with persistent leaves, for acidic soils. Very early bloomer. Several cultivars with colourful winter foliage. The famous briar pipes are made with a Mediterranean species, not this one.
Enkianthus campanulatus Also a shrub suited to acidic soils. Can reach 2 m, with excellent orange-red fall colours. Pretty small flowers in pendant racemes.
Euonymus sachalinensis (E. planipes) Orange and yellow fruit. Long peduncles resembling long earrings. Lovely fall colours. Artist’s charcoal is made from a similar species.
Euonymus alatus Spindle tree with stems notable for their four corky ridges or “wings.” Unique pink-red fall colours, very uniform and constant from year to year.
Euonymus europaeus 'Aldenhamensis' European spindle tree cultivar with lovely red fall colours.
Euonymus fortunei and cvs. Spindle tree with persistent leaves. Several cultivars with variegated leaves take on a pinkish hue in the fall. Some cultivars, like 'Sunspot', 'Surespot' and 'Blondy' have striking yellow variegations. A good choice if you’re looking to brighten up dark corners and like strong contrasts.
Exochorda serratifolia 'Northern Pearls' The pearl-bush (its flower buds look like pearls) will surprise you with its pure white flowers and pretty decorative dry fruit with five ridges. Hardy cultivar.
Forsythia spp. Yellow flowers, very early in the spring. Go for cultivars with hardy flower buds, e.g. 'Northern Gold'.
Forsythia ovata 'Robusta' Remarkable dark purple fall colours. Hard to find. Unreliable bloomer.
Forsythia mandshurica Very hardy forsythia, with unique orange-red fall colours unlike any other forsythia.
