Osteospermum SummerSmile® ‘Cardinal’ – 3 Plug Plants - FREE P&P

Continuing the success of the Proven Winners® SummerSmile® collection, ‘Cardinal’ is a compact, sun‑loving osteospermum that delivers exceptional colour and garden performance. The flowers emerge deep burgundy, then evolve through layers of rich pink, lilac, soft blush and even subtle orange tones as they age, giving a constantly changing display.

This variety is more of a ground‑hugger than others in the series, forming a low, spreading plant that’s ideal for edging, containers, baskets, and filling gaps at the front of sunny borders.
