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.

Alstroemeria 'Butterfly Hybrids'

Peruvian Lily

Now only the pinks and purples have been selected to create this eye-catching mix. One of the easiest cut flowers to grow and definitely one of the most impressive. Height and spread: 60cm (24").

Erigeron glaucus 'Sea Breeze' (Large Plant)

Fleabane

A low-growing, carpeting plant for coastal locations, or any difficult, exposed position in the garden. The lilac blooms come easily, and the Beach Aster or Fleabane as it is commonly known, looks great tumbling over a rock wall, or growing between cracks in paving.
