Slide 1 LHAP 304 SHP: Introduced Shrubs Elder, Wayfaring Tree, Nannyberry, Caragana, Forsythia, Lilac, Cotoneaster, Ninebark, Double Flowering Plum, Barberry, Weigela, Burning Bush, Honeysuckles Slide 2 OLEACEAE The Olive Family Slide 3 Family Characteristics Stems Woody Leaves opposite (mostly) Flowers perfect 4 Sepals, 4 petals (united) 2 Stamens Fruit is capsule, seeds or drupe Slide 4 Syringa species - Lilacs Origin: largely China / or cultivated Hardiness Zone: Z2 - Z4 Exposure: Full sun Soil Conditions: Drought tolerant once established Significant Features... Slide 5 Syringa species - Lilacs Slide 6 Syringa species - Lilacs FOLIAGE/FORM: Height and Spread - typically 3 - 4m tall Shape - Oval Form - many sucker Foliage - simple, entire margins, Usually cordate with acute tip and a bit leathery Slide 7 Large shrub, relatively coarse textured wood, dried inflorescence persists through winter. Ok Potential for nesting - may not provide sufficient protection from attacking birds. Make sure it’s too dense for cats to climb. Slide 8 Syringa species - Lilacs BUD/BARK: Bark - Smooth, Grey with contrasting lenticels. New wood is grey/brown. Hard/Smooth Buds - Typically large, rounded and opposite. Newer cultivars may be more pointed. Slide 9 On the left and in the back, you can see the lilac wood. This bush is growing at my house, it was once a Mock Orange and (I believe) a Villosa lilac but they have grown in together. You can see the Mock Orange branch to the right (wood has vertical lines on it and is exfoliating more) The twigs are also easy to see. The Mock Orange has square/vertical exfoliation whereas the lilac is smooth with white lenticel spots. Slide 10 Syringa species - Lilacs Flower & Fruit: Type - Panicle Colour - White, pink, purple (some are doubles) Season - Early - Mid summer Fruit - capsule with many seeds persists over winter. Other - some have contrasting buds ‘Miss Canada’ Slide 11 Note Lilac Bloom Time: Daylily is vegetative only Ash, dogwood, blue oat, ninebark in full leaf Rose, no blooms. Slide 12 Syringa species - Lilacs Landscape Use: Large sites Hedge or Tree Form Cut flower Sensory Garden Problem soils Winter Interest Maintenance: Prune as soon as flowers are finished. Some do not like the dry flowers. Slide 13 Syringa vulgaris - The French Lilac cultivars of note Large blooms - mid June (week 2 usually, lasting 2-3 weeks) Large plants Very striking MIGHT sucker! Slide 14 Syringa Hybrids: S x hyacinthiflora cultivars Large shrubs Purple-red Fall colour Includes “Bloomerang” and Mount Baker (early bloomer). Earlier than S. vulgaris Slide 15 Syringa Hybrids: Syringa x prestoniae - Preston Lilacs Still large shrubs Non suckering Yellow Fall colour Later blooming than S. vulgaris Slide 16 Syringa meyeri ‘Palibin’ - Dwarf Korean Lilac VERY fine textured.

Slide 22 Forsythia ovata - Forsythia Flower: Type - Single, small connate flowers, blooming on Old Wood Colour - Bright Yellow Season of Bloom - Spring Other - Blooms before leaves Slide 23 Forsythia in Red Deer, Spring 2021, just prior to bloom. Note the dense growth in the lower segments, and most of the flowers on the old wood in the lower section. Slide 24 Forsythia ovata - Forsythia Landscape Use: Mass Plant (if hardy) Accent/Specimen Spring Feature Fall Colour Cut Flower Slide 25 Forsythia ovata - Forsythia Maintenance Considerations: May not bloom if flower buds freeze (chinooks) Prune in early summer (blooms on old wood) Thin periodically to keep it flowering. Slide 26 ROSACEAE Rose Family Slide 27 Family Characteristics Alternate attachment Leaves usually oval shaped & serrate Typically 5 sepals & petals Many stamens Many are edible Slide 28 Physocarpus opulifolius - Ninebark Origin: Native to Eastern N. America Hardiness Zone: 2/3 Exposure: Full sun/Part Shade Soil Conditions: Moist, well-drained soil Significant Features... Slide 29 Physocarpus opulifolius - Ninebark BPasula ‘Dart’s Gold’ Slide 30 Physocarpus opulifolius - Ninebark FOLIAGE/FORM: Height and Spread - Varies by cultivar (medium to small) Shape - Round to oval, but potentially a bit messy. Leaf - Simple, Trilobe, Elongated central lobe, Serrate Margin, COLOURFUL, LATE to break bud! ‘Luteus’ Slide 31 Copyright - Olds College ‘Diabolo’ red fruit in fall Slide 32 Physocarpus opulifolius - Ninebark BUD/BARK: Buds - small, tight.
