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

  • The fast-track to a hassle-free garden - just plant, water and enjoy!
  • Quality plants delivered to your door, hardened off and ready to plant out
  • Fully-grown, super-robust, healthy plants
Our garden ready plants are selected for garden performance, straight from the nursery. We send them to you 'green' ahead of flowering (but please note some varieties may show a few blooms), which means plants will establish quickly and all their energy goes into producing better roots, so they produce more flowers throughout the season.

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").

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").
