About this plant
This large lilac is really a tree rather than a shrub since it can reach over 9 metres in height, at least in its Japanese homeland. It is shrubbier in character in the UK where it is likely to be much smaller, and quite slender. It flowers from mid to late June. The flowers are in the form of good sized broad frothy panicles, coloured creamy white, or yellowish white and having a strong fragrance. The scent has been likened to privet which may be too sweet and sickly for some. It has good plump pointed leaves coloured green and which may be downy to the touch on their underside. The bark is reddish brown and will peel on older plants.

Spring
Spring - late · Outdoors
Feed young plants with slow release fertiliser
Spread a slow release fertiliser around the base of the plant to the edge of the foliage spread, so that it can feed the roots. It is helpful for this to be applied for several years.
This is a simple way to provide a nutrient boost until the plant becomes well established.
Spring-Autumn · Outdoors
Water during dry periods
For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.
Spring-Autumn · Planting
Pinch out growing tips
On young plants pinch out foliage tips to encourage a pleasant and bushy growth habit.
Planting & general
Outdoor planting · Planting
Add root growth stimulant to the planting hole
Mycorrhizal fungi helps roots establish quickly, so they absorb water and nutrients more efficiently. It comes as a powder, granule or gel. Add to the planting hole or container, and to the plant's rootball before planting in the hole. For "bareroot" plants use a gel.
Planting
Protect & support young trees
Attach a newly planted tree or tall shrub over 1m to a tree stake to give support and prevent windrock. Use a tree guard to stop tree bark being eaten by animals, especially in areas with deer - removing bark injures a tree and in worst case can kill it.
