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 '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.

To make the most of your displays, try our exclusive Tower Pot™, specially designed to enable plants to climb easily.
