Plant Profile: Lilacs

In the dooryard fronting an old farm-house near the white-wash’d palings,
Stands the lilac-bush tall-growing with heart-shaped leaves of rich green,
With many a pointed blossom rising delicate, with the perfume strong I love,
With every leaf a miracle—and from this bush in the dooryard,
With delicate-color’d blossoms and heart-shaped leaves of rich green

Walt Whitman

Plant Profile: Lilacs. April 2026.

The nostalgic scent of lilac is decadent and sweet, its heady perfume filling the air. Their symbolic innocence draws our minds to another time, one with black-and-white memories of yesteryear. A time with old cottages and picket fences in small towns. All proper cottage gardens should have a lilac bush or two or maybe three. Lilacs are one of the easiest things to grow in a temperate climate and will reward you each Spring with armloads of pastel panicles, each filled with fragrant florets and heart-shaped leaves. They are beautiful in a vase; they are beautiful heaped on a Spring cake. Lilacs and Spring belong together.

If you plant lilacs, know that they intend to stay for quite a while, for they have a long life. It may be around long enough for you to see your grandchildren playing around them. And conveniently, the care required for lilacs is minimal. They don’t prefer a lot of fuss. All they need is an area with plenty of sun, well-draining soil, and occasional pruning. As lilacs are generous, you very likely will be able to share this plant with friends with its plentiful suckers. They will also give your garden some background foliage with height. Lilacs can serve as a focal point, a border, or even a hedge.

Currently, I am nursing five lilacs in our garden at Hidden Bluff, four of them newish: the common lilac; the old-fashioned, double white Mme. Lemoine lilac (1890); two of the gorgeously sweet fragrant, pinky-lavender Beauty of Moscow lilac; and one creamy yellow Primrose lilac. I may add more! Even if their bloom period is fleeting, they are well worth making room for in the garden.

Soil Preference: Neutral to slightly alkaline; well-draining; loamy; will tolerate some acidity as well (I have grown these in acidic forest soil successfully)

Light Needs: Needs at least 6 hours of sun; although I have found they can grow in partial shade, but not too much, as it affects how much they bloom.

Propagating: Lilacs produce numerous suckers, which are easy to dig up and plant. You can also propagate with softwood cuttings or layering.

When to Harvest: N/A

Maintenance: Low maintenance; hardy; prune right after flowering, as lilacs start forming their flowers for next year in the summer; prune to keep airflow between branches and avoid powdery mildew; add compost in spring, but don’t overfertilize or you may end up with fewer blooms.

Companion Plants: Peonies, catmint, lavender, and roses.

Uses: Excellent cut flowers; attracts butterflies; Edible flowers; makes a delicious syrup (recipe here)!
