I think the name of mine was 'Granny's Ringlets', but it appears to be the same as 'Spiralis'. This plant is growing too large and I need to move it. Does anyone know what the ultimate mature size range for this plant is?
GRANNY'S RINGLETS is an English common name. May be shrubby or treelike. Could be more than one form, or some specimens may become more arborescent after enough time has elapsed. One in Scotland was over 65' high in 1987.
One in Cumbria (northwest England) 29m tall as of 5 years ago, so it's probably broken the 30m mark by now - definitely a tree!
