Mimosa hostilis (syn. Mimosa tenuiflora) ‘Brazil’ | ‘Jurema’, ‘Tepezcohuite’ | Seeds
We’re always looking to offer more variety, so are happy to be stocking this great quality Mimosa hostilis seed, collected in 2018 in Brazil. This is but one of our many UK exclusives, which also include some extremely fresh hostilis seed from our grower in Spain and (extremely limited) quantities of a much rarer, almost thorn-less variety; Mimosa hostilis var. inermis (from our friends in Australia)!
Mimosa hostilis is an important perennial shrub or tree species of the Fabaceae family which is native to parts of Brazil, Colombia, El Salvador, Honduras, Mexico, Panama and Venezuela. Syn. Mimosa tenuiflora, this useful species is commonly known by a variety of informal names, including ‘Black Jurema’, ‘Cabrera’, ‘Calumbi’, ‘Carbonal’, ‘Jurema’, ‘Jurema Preta’, ‘Tepezcohuite’ and ‘Yurema’.
Mostly growing at relatively low altitudes in USDA Hardiness Zones 9-11 (although it has been found as high as a thousand metres or so), hostilis reaches roughly eight metres tall – reaching half of that height within five years or less in good conditions! Covered in dark brown-red-grey bark (more of which below), the tree’s thorny, fern-like branches are the base for finely pinnate, bright-green leaves of roughly five centimetres in length. Fragrant white-whitish flowers – between four and eight centimetres long – occur from November to July in the Northern Hemisphere, September to January in the Southern Hemisphere.
The bark of this species is excellent for use as an organic dye and tanning agent (for its high tannin content) and as a soap-making ingredient (for its high lipid and saponin content). Further, Mimosa hostilis bark is used traditionally in Middle and South America to topically treat burns and wounds, coughs and chest infections, tooth pain and assorted other ailments. The plant is also used as a fertiliser, soil-fixer and fuel, to make charcoal and to build bridges, buildings, fences and furniture and as drought-fodder and parasite preventative for certain livestock species.
Mimosa hostilis is a fast-growing and quite forgiving species when in cultivation, as long as you treat her well! Younger, smaller plants are great as a feature of any indoor collection; if planting outside, do so in USDA Hardiness Zone 9 or higher for best results. Maximise the germination rates via seed pre-treatment (you can go either the scarification or the soaking route – check our Cultivation Guides for more information). Mimosa hostilis seed germinates in two to four weeks at a range of between 10°C to 30°C (roughly 25 °C is best) and – due to their hard seed coat – remain viable for many years. Once germinated, they can either be sown directly into the ground (space around five metres apart if so – they get relatively big), or else planted in containers of sandy, mildly acidic to mildly alkaline soil. Expose to full sun or full sun to partial shade and water regularly in average amounts, keeping the soil slightly moist at all times for best growth. You can also try propagating from cuttings, once you have a mature plant or two.
