4. Purple lilac
After learning which variety of lilac is the most fragrant, now I want to tell everyone that the most fragrant white lilac is actually a variant of purple lilac, so purple lilac is also a very good variety. Purple lilac belongs to the deciduous shrub or small tree group. It is also called lilac, North China lilac, baijie, qingke, and longshaozi.

It is very suitable for courtyard cultivation and is a famous flowering tree.
5. Amur lilac
Amur lilac belongs to the shrub or small tree group, and the tree can reach 10 m tall. In late spring and early summer, it has abundant flowers and lush leaves. Its flowering period is usually from May to June, and its fruiting period is in September. It mainly grows on hillside shrublands or at forest edges and in grasslands.
II. Propagation methods for lilac seeds
1. Sowing and propagation
In autumn and winter, when the capsules turn from green to yellowish brown, the seeds are mature. After collecting the fruit clusters, place them in a ventilated and dry indoor area to dry in the shade; do not expose them to strong sunlight. Thresh when 2/3 of the capsules have split open. Sow in autumn, or select the seeds and store them dry for spring sowing, sowing in open-field beds. The thousand-seed weight is about 15 grams, and the general germination rate is about 65%. Before sowing, soak the seeds in warm water for 2 hours. In spring, stratify them in sand for 1-2 months under environmental conditions of 0-7°C. Sow in beds or ridges, and cover with soil 2-2.5 cm after sowing. Seeds that were stratified in sand emerge in about 15 days after sowing, while those not treated by sand stratification need about 1 month to emerge. In cold northern regions, lift the seedlings in autumn and heel them in for overwintering. In the second year, transplant them at a row spacing of 30 cm and a plant spacing of 15 cm, and by autumn they can grow into 1 m tall seedlings. Then lift the seedlings again and heel them in for overwintering. In the third year, plant them in ridges with a plant spacing of 30-40 cm.
2. Cutting propagation
About 1 month after flowering, select vigorous current-year semi-lignified branches as cuttings, cut them to about 15 cm long, and keep 1-2 leaves at the top. Soak the base of the cuttings in 100 mg/kg indolebutyric acid for 8-12 hours, then insert them into a sand bed at a depth of about 8 cm. Shade and keep moist, and they will root after 1 month. Hardwood cuttings can also be used, and the survival rate of cuttings from the middle and lower parts of branches is significantly higher than that of cuttings from the upper part of branches (with terminal buds).
3. Division propagation
Many small seedlings often sprout under large lilac trees. Dig them out before spring germination and move them to a nursery to cultivate them into large seedlings.
4. Grafting propagation
Grafting is mostly used for propagating excellent varieties. Use European lilac, small-leaf privet, or lilac seedlings as rootstock. Use branch grafting in spring and bud grafting in summer.
From the above, we can know that there are still quite a lot of lilac varieties, but the editor has introduced five lilac varieties in detail for everyone. Each has its own characteristics. If you want to plant them, you can choose one you like. In addition, some propagation methods have also been shared, hoping to help everyone.
