Description 1

Vigorous, rhizomatous plant. Robust appearance. Perennial. Fleshy leaves, ashen in colour in leaf rosette form that can reach 2 m. Thorns along margins and apex, ending thorns of some 3 cm. Its flowers are pale yellow in colour, distributed in great quantity along the length of one stem of up to 10 m (panicle). They are produced in the plant's mature phase (10 years) and once the rosette produces a flowering stem it dies after flowering.

Biology 1

Sexual reproduction by seeds (black, flat and numerous) and asexual reproduction by rhizomes. Flowers between July and September, the plant then dies. Pollination by lepidopterans and bats. Prefers bright areas and well-drained soils, colonising these areas through propagules transported by surface run-off, which reach the substrate and give rise to to new plants. Very resistant to dry conditions and high temperatures. Can withstand light frosts if they are not very frequent.

Habitat 1

Thermophilic plant with great capacity for colonisation, present in a number of habitats. Rocky areas, cliffs, dune systems and even crop fields although it is generally found in areas close to the coast and preferably in sandy soils. Common along roadsides and boundaries of plots. Appears in degraded bushlands and alongside communication tracks in low-altitude coastal areas. Not very common in forest habitats.
