Sundenia® Crimson Dipladenia Plant

The Sundenia® Crimson Dipladenia combines the best of both mandevilla and dipladenia characteristics, offering large 3-5 inch crimson flowers with a more compact and bushy growth habit. Unlike traditional mandevilla vines that grow taller, Sundenia® varieties are more controlled, making them perfect for patios, containers, or hanging baskets. Growing 12-24 inches tall and spreading 18-24 inches, this heat-tolerant plant provides vibrant, showy blooms throughout the season while staying manageable in size.
