Lilac – Royalty (Preston Lilac)

Late-blooming elegance with fragrant purple blooms and northern hardiness.

The Royalty Lilac (Syringa × prestoniae 'Royalty') is a robust, cold-hardy Preston hybrid lilac developed in Canada, known for its rich purple flower clusters and upright, vase-shaped form. Blooming later than common lilacs, Royalty extends the lilac season into early summer and fills the garden with classic lilac fragrance long after others have faded.

Its strong, upright habit and lush green foliage make it ideal for hedging, privacy screens, or as a tall, fragrant focal point in the landscape. Exceptionally hardy and resistant to mildew, Royalty is a dependable choice for gardeners in colder climates seeking long-lasting beauty with minimal upkeep.
