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.

Erysimum, Cheiranthus

For hassle-free gardening, look no further than our pre-planted pots for easy seasonal colour. We're always on the lookout for ways to make life simpler for our gardening customers.

Winner in the 'Best New Bedding Plant' category at the Grower of the Year Awards 2013, this is one of the most exciting wallflowers to emerge in recent years. Dense, fragrant flower spikes in shades of cream, yellow, red and purple appear not only in the spring, but throughout the autumn too, blooming in just 6 weeks from an August planting! With a delightful sweet fragrance and compact, multi-branching habit, Wallflower 'Sugar Rush' is perfect for beds, borders, containers and window boxes, creating a mass of colour and scent when much of the garden is dormant.

Hesperis matronalis (Large Plant)

Sweet Rocket

Hesperis matronalis is at its best when grown in large drifts, leaving plenty to spare for early summer bouquets. Fragrant clusters of bloom, coloured pale lilac to purple, are produced from May to July. The richly scented flowers of Sweet Rocket are irresistible to pollinating insects, making this an excellent choice for both wildlife areas and the herbaceous border. Although Hesperis is a biennial or relatively short-lived perennial, it will happily seed about to create swathes of bloom that will perfume the air on warm summer evenings. Height: 90cm (36"). Spread: 45cm (18").,

Culinary note: Some parts of these flowers are edible. For more details about edible flowers click here.
