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 'Jackpot Mixed' F1 Hybrid (Garden Ready)

Pelargonium, Zonal Geranium, Zonal Pelargonium

 Customer Rating
  • 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.


These weather tolerant, F1 hybrid pelargoniums have more than enough vigour to ensure a spectacular, free flowering display throughout summer. Geranium 'Jackpot Mixed' produce masses of colourful single blooms on neat compact plants. Perfect for filling beds, borders and patio containers. Height: 40cm (16"). Spread: 35cm (14").


Although technically perennial, Pelargoniums are only half hardy and therefore normally treated as annuals in the UK. However, with care, they may be overwintered in a frost free greenhouse.

Blechnum brasiliense 'Volcano'

Dwarf Brazilian Tree Fern, Hard Fern

  • New in 2015
Are Dicksonia tree ferns too large or expensive for you? We've found the answer - try the dwarf Brazilian tree fern instead! Blechnum brasiliensis 'Volcano' is an exciting new find for the home gardener, only recently introduced to the UK, but sure to be the next big thing! Compact plants lend themselves well to growing in patio pots; and throw up huge fronds up to 70cm (28") tall. The young fronds unfurl in a bronze volcanic hue turning a shiny green as they open. A relative of our native Deer Fern, this tender exotic fern thrives in low light, so it's perfect for giving a tropical touch to your home and garden. With tropical origins, Blechnum brasiliense is hardy enough to be grown in most UK gardens but will appreciate a sheltered spot and some winter protection. Height: 90cm (36"). Spread: 70cm (28").

Geranium maderense

Giant Herb Robert, Madeira Cranesbill

  • RHS Award of Garden Merit
  • The palm tree geranium
Geranium maderense is a magnificent tender perennial. The Madeira Cranesbill is the largest of the Geranium species, and certainly one of the most impressive, reaching a height of 1.5m (4',9"). Although perennial, it often acts as a biennial, producing pretty magenta pink blooms in its second year. But you won't mind the wait - it will give you time to appreciate the exotic-looking, dissected, evergreen foliage that radiates from a stout central trunk. This spectacular RHS AGM species will need some winter protection so it is best grown in the conservatory or a large patio container which can be moved to a frost free position in winter. Height: 150cm (59"). Spread: 100cm (39").
