Miss Kim lilac

Sun

Full sun, ideally at least 6 hours daily; tolerates light shade but flowers less freely.

Water

Water regularly while establishing; once established, water deeply during prolonged dry spells. Avoid persistently wet roots.

Soil

Well-drained, moderately fertile soil, preferably neutral to slightly alkaline; tolerates clay if drainage is good.

Height

6-8 ft (1.8-2.4 m)

Spread

5-7 ft (1.5-2.1 m)

Flowers

Late spring to early summer; purple buds open to fragrant pale lavender flowers that fade lighter.

Foliage

Small, oval, dark green leaves, often turning burgundy or reddish purple in autumn; colour varies with climate and weather.

Growth rate

Slow

• Plant with the root flare at soil level in a sunny position with good air circulation.
• Water deeply through the first growing season whenever the root zone begins to dry.
• Apply 2-3 in (5-8 cm) of organic mulch, keeping it clear of the stems.
• Top-dress with compost in spring; avoid high-nitrogen lawn fertiliser near the roots.
• Allow room for its mature width rather than keeping it small by repeated clipping.

Pruning. Prune only as needed, immediately after flowering: remove dead or crossing branches and shorten wayward shoots. For gradual renewal, remove a few of the oldest stems at ground level; late-summer or winter pruning removes the following spring's flower buds.

Early spring

Refresh mulch and add a light compost top-dressing without burying the stem bases.

Spring

Check new growth for aphids and water newly planted shrubs during dry weather.

Late spring

Enjoy the flowers; remove spent clusters if you prefer a tidier appearance.

Early summer

Once flowering finishes, carry out any shaping or selective renewal pruning.

Summer

Water deeply during extended drought and avoid overhead watering if leaf disease develops.

Autumn

Plant while the soil is workable, allowing time for roots to establish before severe frost; leave healthy established plants unpruned.

• Place near a path or sitting area where you can enjoy the spring fragrance, leaving space for its mature spread.
• Use as a flowering anchor in a mixed border with peonies, catmint and hardy geraniums.
• Plant several as an informal flowering hedge rather than a tightly clipped screen.
• Use its rounded outline and autumn colour beside a lawn or at the edge of a sunny courtyard.

Garden styles it suits: Cottage garden, Traditional, English country, Sensory garden, Pollinator garden and Low-maintenance.

Plant it with: Peonies, Catmint, Hardy geraniums, Salvias, Daffodils and Daylilies.

Wildlife: Flowers attract bees, butterflies and other nectar-feeding insects. The branching growth provides some shelter for small birds.

• Few flowers: insufficient sun, late pruning or excessive nitrogen are common causes. Provide full sun, prune only just after flowering and avoid heavy feeding; very mild winters can also limit bloom.
• Powdery mildew: Miss Kim is relatively resistant, but leaves may develop a white coating. Improve airflow, avoid crowding and remove fallen affected leaves.
• Bacterial blight: young shoots may blacken and die, especially in wet spring weather. Cut affected growth back into healthy wood in dry weather and disinfect tools between cuts.
• Poor drainage: yellowing leaves, weak growth and root decline can follow prolonged waterlogging. Correct drainage or move the shrub to a better-drained position.

Not known to be toxic to cats, dogs, horses or people; no part is recognised as poisonous. Eating plant material may still cause mild stomach upset, so discourage pets and children from chewing it.

• Common lilac (Syringa vulgaris)

  Usually taller, with larger, heart-shaped leaves and an earlier flowering season; it commonly produces more suckers.

• Palibin lilac (Syringa meyeri 'Palibin')

  Usually forms a lower, denser mound with smaller, broadly oval leaves and pinkish-lilac flowers; it generally flowers a little earlier than Miss Kim.

Syringa comes from the Greek word syrinx, meaning pipe, referring to stems whose soft pith could be removed to make a hollow tube.

Propagation. Take softwood cuttings in early summer and root them under humid conditions in a free-draining medium. Cuttings preserve the cultivar; seedlings will not reliably resemble Miss Kim.
