Syringa vulgaris

Syringa vulgaris, more widely known as the common lilac, is a highly fragrant, spring-flowering shrub or small tree native to the Balkan Peninsula.  Lengthy panicles of dense, four-petaled, delicate blooms carrying a powerful, sweet aroma make the common lilac a standout amongst other hedge plants.  Spring brings its blooming period, which lasts from four to six weeks.  Hundreds of cultivars are available, including single and double flowers in colors ranging from cream-white to rose, to lavender.  Given the right climate, the common lilac can be used as a screen or hedge, and some dwarf varieties can even be potted and kept indoors.  Dark green, heart-shaped leaves grow in an opposite pattern along the stems in a dense dispersal pattern and remain splendid in the summer.  Unfortunately, the common lilac does not fair well in the intense heat of southern climates, as the buds need a long winter chill to mature and bloom in the spring.  There are varieties that require less chilling, but their requirements still keep them rather limited in US hardiness zones above 8.  Most find the sweet fragrance to be delightful, but it may cause discomfort in individuals with asthma.  

Plant common lilac in a space that receives copious sunshine to encourage a larger volume of blooms, though the plant will still grow in partially shaded areas as well.  Loamy, well-draining, and slightly alkaline soil is ideal for common lilac plants.  Maintaining lightly moist soil through regular watering is optimal, and the watering frequency should be increased during extended stretches of intense, dry heat.  Excess nitrogen can be harmful to common lilac plants, and fertilizing should not be necessary for several years after planting.  Lilacs should be planted in the fall, after their leaves begin to fall but before the ground becomes frozen.  Learn more in the Plant Story community!
