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.

Cyclamen hederifolium (Large Plant)

A delightful little plant producing delicate pink flowers with reflexed petals in the autumn. Often emerging after the flowers, the heart-shaped deep green leaves are patterned with silver, creating a striking marbled effect. Cyclamen hederifolium is a superb ground-cover plant in rock gardens and woodland gardens where it will self-seed freely to create carpets of foliage and flowers from autumn to spring, before the foliage dies back in summer. Height: 10cm (4"). Spread: 15cm (6").

Wallflower 'Sugar Rush'

Erysimum

 Customer Rating
  • 'Best New Bedding Plant' at the Grower of the Year Awards
  • Autumn and spring flowering
  • Super-vigorous
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. Versatile and undemanding, wallflowers are tough enough to cope in even the poorest soils. Height and spread: 30cm (12").
