Discover the Dwarf Mexican Petunia

Ruellia 'Katie' (also sold as 'Katy' or 'Nolan's Dwarf') is a compact, well-behaved cultivar of the Mexican petunia (Ruellia tweediana, syn. R. brittoniana). Unlike its aggressive species counterpart, this dwarf selection stays neat and tidy, making it perfect for smaller gardens and containers.

Botanical Details

Compact Growth & Continuous Blooms

This dwarf perennial forms a tidy mound just 10-12 inches tall and wide, producing an endless succession of trumpet-shaped, petunia-like flowers in soft lavender-pink from spring through frost. The narrow, dark green foliage remains attractive all season.

'Katie' thrives in full sun to partial shade and adapts to various soil types, including wet conditions. It's remarkably heat and drought tolerant once established. Hardy in USDA zones 8-11, it may die back in winter but returns reliably in spring.

Versatile Landscape Uses

Ideal for border fronts, rock gardens, mass plantings, and container gardens. Its compact habit eliminates the invasive tendencies of the species. Excellent for pollinator gardens—butterflies and hummingbirds love the nectar-rich blooms. Low maintenance and deer resistant.
