In flower

How to tell it

Rosettes of fleshy spoon-shaped leaves, pale green, covered in glandular hairs that make them clearly sticky to touch, which is the mark and gives the scientific name. Woody branched stems. A dense pyramid inflorescence of yellow flowers with seven to ten petals. Range: endemic to Madeira.

What it is confused with

Flat-rosette aeonium

Aeonium glandulosum

Harmless confusion

Both are Madeiran and sticky. This has a woody stem and upright rosettes; the flat-rosette one grows pressed to the stone, almost stemless, its rosette flat as a plate. Neither is harmful.
