Polypodium 'Green Wave': Twister Fern

Polypodium 'Green Wave' (Twister Fern) is a distinctive cultivar of the common polypody selected for its uniquely twisted, undulating, and crested frond margins. The leathery, deep green fronds have a ruffled, wavy appearance that adds great texture. It retains the creeping, rhizomatous habit of the species, forming a low, spreading clump. The rhizome is sweet, licorice-flavored.

Plant Profile

'Green Wave' shares the species' adaptability: it grows in shade to part sun, on well-drained, acidic to neutral substrates. It is excellent for dry stone walls, rock gardens, containers, and as a textural groundcover in dry shade. The crested, wavy fronds catch the light beautifully. Tough, evergreen, and low-maintenance. A fun, collectible cultivar.
