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.

Delphinium 'New Millennium Dwarf Mixed'

  • New in 2015
We source our delphinium stocks from the best breeder in the world to guarantee top performance from our plants in your garden. The towering flower spires that make delphiniums a must-have garden perennial, can require sturdy staking to prevent them flopping under wind and rain. We're looking to change that with Delphinium 'New Millennium Juniors Mixed'. The sturdy upright stems don't need any staking or support, but give the same cottage garden feel as traditional varieties. From the world famous breeding of Terry Dowdeswell in New Zealand, these shorter, sturdier plants have been bred to perfection, with clear colours, evenly spaced florets, long flowering and high disease resistance. Height: 75cm (30"). Spread: 60cm (24").

Physalis alkekengi var. franchetii (Large Plant)

Chinese Lantern

Physalis alkekengi var. franchetii is better known by its culinary name of Cape Gooseberry. Tiny, creamy-white flowers appear in midsummer above oval green foliage. This hardy perennial is mainly grown for its edible berries which later develop within red, papery Chinese Lantern calyces. This vibrant autumn display brings a bright splash of colour to fading perennial borders. The stems can be cut to create wonderful decorative flower arrangements. If left on the plant the calyces will slowly skeletonize, adding ornate winter interest to your garden. Height: 75cm (30"). Spread: 90cm (36"). More info
