Common lilac (Syringa vulgaris) is also called English lilac or French lilac. They come from the Balkan Peninsula in southeastern Europe. It belongs to the same family as the olive tree (Olea europaea) and shares the native Oleaceae. This deciduous shrub is a perennial plant that will remain dormant every winter and return with new growth every spring. Syringa vulgaris is known for its clusters of purple flowers and sapphire-green heart-shaped leaves. The Lilac can grow up to 15-20 ft tall and look like a small tree, but is actually a multi-stemmed shrub that is known to extinguish root suckers. These Pistons can be dug up and transplanted to another area of the garden for easy reproduction. Although it can grow very large, regular pruning can help keep it at a more manageable size.
The Lilac has a notoriously short flowering time that lasts only a few weeks, starting in mid-spring. It is best to finish them as soon as the flowers are consumed, so that the energy remaining in the plants can concentrate on setting the roots for the winter. The common lilac requires a certain amount of winter cooling hours to break the rest in the spring and thus bloom. For this reason, they are not easily grown in hot climates.
Popular varieties of lilacs
The common purple lilac is the most famous variety out there. After all, when you hear the word ‘lilac’ used to designate a color, you often think of light purple with a pink tint, which is the shade of this widely available plant. Bloomerang varieties are an interesting prospect for those who contrition the short flowering time of this plant. They begin to bloom in May along with other varieties. They will have to be headless after their first flowering, and after a mid-season break, they will put new growth and bloom again in after summer and autumn. They add a beautiful autumn color to the garden at the end of the season.
Korean dwarf is an excellent option for gardeners who are tight in space. This species is often pruned to look like a small tree rather than a shrub. It has an mature spread of 4-6 ft. This can be beneficial when planting if you don’t have 15ft of space to dedicate to this plant. Madame Lemoine is one of many French hybrids known for its white floral flowers. White lilac is beautiful in the garden and smells equally fragrant. They can add interest to a long row of bushes and break the violet with white spots.
Sun and temperature
When planting your lilac, choose a place with full sun. These plants need at least 6-8 hours of sunlight per day. It tolerates light shade, but can not bloom so abundantly with less exposure to sunlight. USDA recommended growth areas for Syringa vulgaris are zones 3-7. As mentioned above, the bat copes best with a certain amount of hours of winter cold, generally around 2000 hours spent below 45 degrees. This rest period allows the buds to ripen and will bloom only after meeting the cooling requirements. This will prevent the plant from blooming too early, while it is still winter, when there may be a warm rogue day in January or February. Lilac is known to be extremely frost-resistant (up to -40 degrees) and does best in places with a cold winter.
Water and humidity
One of the things that makes lilacs so easy to care for is that they are very tough and are considered drought tolerant. If you forget to water them, they will probably be fine! But for the best results and the most flowers, there are a few best practices to follow. This plant prefers moist soil, but does not do well when overloaded. Deep spraying with a suction hose every two weeks gives the best results. If you live in an area that regularly receives measurable rainfall throughout spring and summer, then you may not need to spray it at all. As soon as the leaves have fallen and the plant is again at rest in the fall, watering is no longer necessary. Be sure to water at the base of the plant to avoid wetting the Leaf, as this can cause mold problems.
