Description

Agave macroacantha produces a medium-sized leaf rosette that can be basal or can grow on a very short stem. Leaves are succulent, greyish green and up to 1.8 feet long at a maximum, ending in sharp black spines that are up to 1.2 inches long at the tips. Flowers are small, grey and red, growing in bunches on sturdy stems of up to 3 m (10 feet) in height.[4]

Cultivation

The plant prefers a dry, sunny and hot location for summer and from early autumn onwards a cooler, well-lit space. It likes regular watering in summer and only minimum watering in winter, and will fare well in a large pot with sparse, gravelly soil.[5][1][6]

In the UK this plant has gained the Royal Horticultural Society’s Award of Garden Merit.[7]
