Syringa x hyacinthiflora was first raised by the French nurseryman Victor Lemoine in 1876, crossing S. oblata with S. vulgaris to push the lilac bloom date earlier in the season. The epithet hyacinthiflora acknowledges the visual resemblance of the flower clusters to the classic garden hyacinth, and the comparison holds well when the panicles are at their peak. Plants reach 10 to 12 feet at maturity with a broad, upright habit, and the color range across cultivars is wide: pinks, lavenders, whites, and deep purples are all available in single and double forms.

Perhaps its most practical advantage over common lilac is genuine resistance to powdery mildew, which spares the gardener the shabby late-summer foliage that plagues many Syringa vulgaris plantings. Full sun is the prescription for best flowering, and neutral to slightly alkaline soil suits it better than acidic ground. Over-fertilizing, particularly with nitrogen, tends to produce lush leafy growth at the expense of blooms. Zones 3 through 7 provide the cold-winter dormancy this hybrid needs, though a handful of cultivars with low chill requirements extend the range into warmer climates.
