Blechnum brasiliense 'Volcano'

Dwarf Brazilian Tree Fern, Hard Fern

  • New in 2015
  • Hardy down to -5c in the UK
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!

Daylily 'Stella in Red' (Large Plant)

Hemerocallis

They always say daylilies are un-killable, and we think that's quite accurate; plants are hardy, very tough, will grow in most positions, producing lily-like flowers. Daylily 'Stella in Red' has ruby-red, gently fragrant flowers, which last a day each, but are borne on compact, grassy plants all through the summer. Plant up Hemerocallis plants into mixed garden borders or large pots. Daylilies are ideal for beginners and smaller gardens, are rabbit resistant, and last many years. Height: 30cm (12") and Spread: 45cm (18").

Culinary note: Some parts of these flowers are edible. For more details about edible flowers click here.
