Blechnum brasiliense 'Volcano'

Dwarf Brazilian Tree Fern, Hard Fern

  • New in 2015
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! Compact plants lend themselves well to growing in patio pots; and throw up huge fronds up to 70cm (28") tall. The young fronds unfurl in a bronze volcanic hue turning a shiny green as they open. A relative of our native Deer Fern, this tender exotic fern thrives in low light, so it's perfect for giving a tropical touch to your home and garden. With tropical origins, Blechnum brasiliense is hardy enough to be grown in most UK gardens but will appreciate a sheltered spot and some winter protection. Height: 90cm (36"). Spread: 70cm (28").
