A
self-pollinated seedling of H.
'Green Edge', this cultivar was registered by
Paul Aden in
1976. It is a large plant with broadly ovate leaves and pale
lavender flowers in mid-July to August.
According to
The Hostapedia by Mark Zilis
(2009), "Despite being introduced nearly thirty years ago,
'Chartreuse Wedge' remains a scarce commodity. I've only seen a
few specimens over the years."
Similar cultivars include H. 'Elatior',
H. 'Green Wedge' and H. Sum
and Substance'.
Seedlings include H. 'Green Dragonet', H. 'Green
Sheen' and H. 'Isle Royal'.
