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.

Erigeron glaucus 'Sea Breeze' (Large Plant)

Fleabane

A low-growing, carpeting plant for coastal locations, or any difficult, exposed position in the garden. The lilac blooms come easily, and the Beach Aster or Fleabane as it is commonly known, looks great tumbling over a rock wall, or growing between cracks in paving.

Erigeron plants are tough and easy to establish, some may even refer to them as 'foolproof'. The Beach Aster is long-lived too, will flower right through the summer, and self-seed if you'd like it to! Height: 30cm (12"). Spread: 45cm (18").

Foxglove 'Illumination Pink'

Digitalis

 Customer Rating
  • Winner of Plant of the Year 2012 - RHS Chelsea Flower Show, Best new product at the Anglian Business Awards, Best new product at the Garden Retail awards
  • T&M's own breeding

Thought to be an impossible hybridisation, this is the most spectacular foxglove you will have ever seen! Parentage from the little-known Isoplexis (Canary Island Foxglove) gives this exciting new Digitalis its fabulous tropical colouring. Being completely sterile Foxglove ‘Illumination’ won’t set seed, giving it an incredibly long flowering period. Unlike most foxgloves which are generally biennial, this half-hardy semi-evergreen is a true perennial so you will be able to enjoy its flowers for years to come. The exotic looking blooms are densely packed on sturdy stems, with many side branches, making a striking addition to summer borders. Height: 90cm (36"). Spread: 45cm (18").
