Arkham’s Botanical is especially in love with the ferny and thorny species Mimosa hostilis (syn. Mimosa tenuiflora)! We’re privileged to offer several types of extremely fresh Mimosa hostilis seed, which we source from a couple of our expert growers from sunnier climes. Further, our Mimosa hostilis root bark is always ethically sourced from sustainable supplies (from farms in Brazil, unless otherwise noted).

A fantastic perennial tree native to parts of Brazil, Colombia, El Salvador, Honduras, Mexico, Panama and Venezuela, this medically and economically-important plant is generally known by names such as ‘Black Jurema’, ‘Cabrera’, ‘Calumbi’, ‘Carbonal’, ‘Jurema’, ‘Jurema Preta’ and ‘Tepezcohuite’. This species grows easily in USDA Hardiness Zones 9-11, but in our experience is also happy in Zone 8 – provided it can live indoors in winter. Hostilis is a fast-growing small tree or shrub which soon grows to eight metres or so in height. Its thorny branches sprout delightfully green, finely pinnate leaves, followed by the appearance of delicate, attractive and sweet-smelling flowers, white to whitish and approximately four to eight centimetres long.

Hostilis bark is valued commercially and by hobbyists as an organic dye and tanning agent and as a popular soap-making ingredient. It’s long been used for these purposes in Middle and South America too, as well as to topically treat burns and wounds, coughs and chest infections, tooth pain and other illness. Other uses for this impressive natural resource include as drought-fodder, fertiliser, fuel and timber.
