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.

Geranium 'Skyrocket® Mixed'

Pelargonium

 Customer Rating

Wow - a new climbing geranium, growing 1.8m (6') in a season! Precise German breeding has developed these top quality plants, so they are guaranteed to give a superb performance. Five of the brightest colours you've ever seen, set against fresh-green foliage. The extra long stems are smothered with rainbows of colour that make a surprisingly good cut flower! As the stems increase in length, tie them onto a support such as a freestanding climbing frame or tower pot, using soft twine to train them upwards. Geranium 'Skyrocket' Mixed also makes a superb trailing plant too – just perfect for trailing from window boxes. Height: 1.8m (6'). Spread: 60cm (24").


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.
