Perennial & Biennial Plants


In this range you'll find an impressive selection of perennial plants and biennial plants, which are perfect for beginners and experienced gardeners alike. Also known as herbaceous plants, perennial plants live for 2 or more years and flower every year. Biennial plants live for up to 2 years, flowering profusely in their second year before setting seed and dying. Both are great for beds and spring displays and there are many delightful plants to choose from.

Morina longifolia (Large Plant)

This handsome evergreen perennial forms basal rosettes of attractive, glossy foliage with spiny margins and a lovely citrus aroma. From midsummer, Morina longifolia bears imposing, upright stems that are tiered with whorls of white, waxy flowers. As the blooms are pollinated they turn to pink, and eventually red, so that one single stem may carry three different colours for you to admire. The whorlflower is a fascinating specimen for perennial borders and makes a pleasing cut flower too. Height: 90cm (36"). Spread: 30cm (12").
