Blechnum chilense cordatum parablechnum
CHILEAN HARD FERN
SKU: 1016-020
Description
Parablechnum cordatum (synonyms Blechnum cordatum, Blechnum chilense), the Chilean hard fern or costilla de vaca, is a fern which grows to 0.9–1.8 m (2 ft 11 in–5 ft 11 in), often developing a trunk-like appearance over time. This plant has gained the Royal Horticultural Society's Award of Garden Merit. The 'seeds' are actually spores, and are extremely tiny.
Type: Hardy perennial
Height: 5-6 feet
Hardiness zones: 7-9
Seeds per pack: 20 spores (extremely tiny and fine)
Germination: Start these seeds right away for best germination rates. Start indoors. Soak a seed-start mix with boiling water to kill parasites. Allow to drain and cool for about an hour. Tap the spores onto the surface of the growing mix. Cover the pots with plastic, or place in a clear plastic bag. Place in a well lit window or under grow lights, but not in direct sunlight. Water from a bottom tray as to not disturb the spores. Keep at 20-22 °C, 68-72 °F. The ferns will start to germinate in a few weeks, though could take a few months to form little plants. Patience is required, though they are well worth the wait!
