About this plant
Antirrhinum majus 'Potomac Royal' produces densely packed spikes of deep rose-pink flowers from late spring through summer, bringing vibrant color and vertical interest to the garden. Narrow, lance-shaped leaves are medium green and arranged along sturdy stems, forming a neat, leafy framework that supports the blooms. The flowers open progressively from the base of each spike upward, extending the display while attracting bees and other pollinators throughout the season. Their distinctive dragon-shaped blossoms add texture and detail to planting combinations.
Originating from a species native to the Mediterranean region, this cultivar reflects modern breeding focused on abundant flowering and strong garden performance. It is well suited to borders, cutting gardens, containers, and seasonal displays, where its colorful flower spikes provide structure and long-lasting seasonal interest.

Design tip
Summer flowers carry the middle of the season, so place it where the bed needs color once spring bulbs fade. In full sun it holds its shape best, and grouping several together keeps the color strong enough to be seen from across the garden.
