Furcraea foetida Seeds | Mauritius Hemp
LATIN NAME: Furcraea foetida
COMMON NAME: Mauritius Hemp
Plant Profile
Mauritius hemp is a rosette the size of a small car, and it means it. The leaves are sword-shaped, two metres long, fleshy, blue-green and usually unarmed along the margins — a detail that separates it from most Agave — and they rise from a short trunk in a dense, arching fountain. After eight to fifteen years the plant does the thing that ends it: a flower spike pushes up six to ten metres in a few weeks, carrying hundreds of greenish-white bells along branching arms. The rosette dies after flowering, but by then the spike has produced hundreds of bulbils on the upper branches, and each one will root where it falls. Native to northern South America, it was carried to Mauritius for fibre in the nineteenth century and has since naturalised across the tropics and subtropics.
Science & Biotechnology
Furcraea sits in Agavoideae, and like most of its relatives it runs CAM photosynthesis, opening its stomata at night to fix carbon and closing them through the heat of the day. That is what allows a plant of this size to survive on rainfall that would kill an ordinary shrub. The leaves yield a hard, pale fibre — sold as Mauritius hemp, pita floja or fique depending on origin — that is softer and finer than sisal and was once woven into sacks, cordage and horse harness. The genus also carries hecogenin and other steroidal saponins in useful concentration, and Furcraea was for decades a commercial source of sapogenins for corticosteroid synthesis before the industry moved to synthetic routes. The bulbils are pure cloning, which is precisely why the plant is so good at escaping gardens.
Uses & Benefits
In a large garden or a dry park it is a sculpture: one specimen on a gravel slope will dominate a bed for a decade and then put on a flowering display that lasts a month before the whole thing collapses. The fibre has a long history in Mexico and Colombia, where fique from Furcraea is still spun into sacks for coffee and potatoes, and the dried leaves are used for thatch and for weaving. It is not a plant for a small garden, a frost pocket, or anywhere near a footpath, since the leaf tips are sharp enough to do damage. In coastal Queensland, Hawaii, parts of the Pacific and South Africa it is a declared or listed invasive, spreading by bulbils into bushland and cliffs; check the local status before planting it outdoors.
Growing from Seed
Seed is viable but slow, and most plants in circulation come from bulbils, which is what a packet of this species usually contains. Sow the flat black seed on the surface of a gritty mix, cover it lightly, keep it at 22 to 26 °C and expect germination in three to six weeks. Bulbils are easier: press them into barely moist sand and they root in a fortnight. Either way, grow the young plant in full sun and lean, sharply drained compost, and water only when the pot has dried right through. Plant out after the rosette is a foot across, on a slope or a raised bed, with at least two metres of clearance. Once established it needs nothing but an occasional removal of dead lower leaves, and it will flower when it is ready, not when you are.
Our Take
A dramatic, slightly dangerous plant for a dry garden with room to spare, and a cautionary example of how easily a fibre crop becomes an invasive.
