Description
Ornemental ivy – Hedera helix ‘Triton’
In a nutshell
Ornamental ivy, Hedera helix ‘Triton’, is a bizarre variety with small, dark matte-green, sharply cut leaves.
The leaves are composed of 5 thin, pointed lobes, directed forwards, twisted downwards and deeply divided. Some see them as long, claw-like hands.
Ivy is somewhat versatile and unstable, requiring regular cleaning to maintain type, but is an interesting plant for ground cover, hanging baskets, pots, rock gardens and even topiary.
History
This cultivar may be a mutation of ‘Green Ripple’. It was cited in a Dutch horticultural magazine in 1965 by van der Laar. It circulated in Great Britain in the 1970s under the name ‘Green Feather’ or ‘Macbeth’. However, it was not described until 1980 by Rose.
