Mimosa hostilis (syn. Mimosa tenuiflora) | ‘Jurema’, ‘Tepezcohuite’ | 25 seeds
We’re extremely proud to be able to offer this incredibly fresh Mimosa hostilis seed, hand-collected in late October 2018 by one of our wonderful Spanish growers…you guessed it, it’s another Arkham’s Botanical UK exclusive!
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’ and ‘Tepezcohuite’.
Usually 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 and is capable of reaching half of that 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!
You really don’t get Mimosa hostilis seed much better than this – short of harvesting them from your own plants! We’re also currently in possession of very limited stocks of a rare, almost thorn-less variety of hostilis; Mimosa hostilis var. inermis, originating from our friends in Australia, plus hostilis seeds collected in Brazil too.
