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. Use the selections in the left menu to select the right plants for your garden.

Geranium 'Rosebud Collection'

Pelargonium, Rosebud Geranium, Ivy-leaved Geranium, Ivy-leaved Pelargonium

Captivating rosebud blooms open to reveal large clusters of fully double flowers on vigorous, trailing plants. Geranium 'Rosebud Collection' includes 5 varieties - 'Red Sybil', 'Pink Sybil', 'Black Rose', Blue Sybil' and 'White Rose'. These varieties have been specially selected because the blooms never open fully, but remain in a truly elegant rosebud formation. Their long flowering period and drought tolerance make these trailing Pelargoniums ideal for creating an enchanting display in window boxes, patio containers and hanging baskets that will last well into autumn. Trails to: 45cm (18"). Spread: 30cm (12").

Although technically perennial, Pelargoniums are only half hardy and therefore normally treated as annuals in the UK. However, with care, they may be overwintered in a frost free greenhouse.

Tricyrtis 'Mixed'

Tricyrtis formosana, Jewel Lily, Toad LIly

An unsung garden hero in our opinion. Tricyrtis thrives in damp shady corners where many other plants would struggle, rewarding you with laddering stems, bejewelled in speckled blooms in three different colours. Sometimes known as the Jewel Lily, or the less attractive Toad Lily, we're sure you'll fall in love with the beauty of this unusual hardy perennial. Height: 75cm (30"). Spread: 70cm (28"). More info
