Rhaphidophora hayi
Roof-Tile Rhaphidophora
Morphology
About
Rhaphidophora hayi, described by Boyce and Bogner, is an adhesive climbing aroid from wet tropical forest spanning Papuasia to northern Queensland — its stem following tree trunks and firm surfaces closely, attaching by roots at the nodes while the entire leaves remain pressed flat against the support in a permanent shingling arrangement. The overlapping blades of this species create a characteristic roof-tile formation — the origin of its common name — and this pattern distinguishes hayi from related Rhaphidophoras that eventually produce projecting or divided adult foliage. Short internodes, adhesive roots and entire green leaves held completely flat are the defining features; the plant never leaves the shingling phase. In cultivation, hayi is grown mounted on flat bark panels, where it spreads laterally in a manner as architectural as it is botanical.

Market Analysis & Price Guide
Historical auction metrics and live online retailer listings updated weekly.
How prices are calculated: The AA Price uses verified eBay UK completed auction data — we take the trimmed mean (removing the top and bottom 20% of prices) to produce a fair-value guide that excludes outlier sales. When recent auction data is unavailable, the AA Price falls back to the current UK retail average from tracked stockists. Retail prices are scraped from active UK plant shop listings and reflect what you would pay buying directly from a retailer today. All prices are in GBP and updated automatically.
