| Trippitt's Crested | Cristatum Group | Polypodium cambricum | A rare cultivar with fronds bipinnatifid with neat crests on all the tips. Height 7-20cm (3-8ins). Raised by Bob Trippitt about 1975 | Like all cambricums it likes some lime in the soil and good drainage. Winter green looses it fronds in late spring and comes back into frond in August, September when it gets enough rain or a hose pipe. I grow mine in the greenhouse were it stays green all year as it is watered regularly. Ideal for dry spots will take a lot of sun or shade | Roger Golding / Julian Reed |
