H. azorica can be found in slopes, rock, soil and trunks of trees, especially in the laurel forest.

Very plentiful on the rocky slopes of Lagoa do Fogo, in São Miguel.

It is a woody climber shrub or perennial bush, which climbs by means of aerial rootlets which cling to the substrate.

Its stems are green and the leaves are large, alternate, and there are two types: palmately lobed juvenile leaves on creeping and climbing stems, and unlobed cordate adult leaves on fertile flowering stems exposed to full sun (usually high in the crowns of trees or the top of rock faces).

This plant's flowers are in small umbels, tight and erect, with a long peduncle.
