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 'Double Flowered Collection'

Hardy Geranium, Cranesbill

Enjoy our selection of the very best double-flowered cranesbills. Every bloom is a pretty posy of vibrant colour and unlike their single flowered relations, these hardy geraniums won't self seed, so the flowers last even longer. These cottage garden favourites will quickly blend with other herbaceous perennials to create colourful groundcover, and look equally attractive in borders or containers. Height: Up to 90cm (36"). Spread: 60cm (24").
  • Collection comprises 1 plant each of:
  • Geranium himalayense 'Birch Double' (left) - Vigorous and versatile, this superb cranesbill tolerates almost any situation; even full shade.
  • Geranium pratense 'Laura' (bottom right) - Long lasting, weather resistant, double white flowers are produced from June onwards on upright, downy stems.
  • Geranium pratense 'Summer Skies' (top right) - The double blooms of Geranium pratense 'Summer Skies' may look delicate but this hardy herbaceous perennial is tough and undemanding.

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
  • World Exclusive
  • 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").
