Mimosa hostilis ‘Inermis‘ | ‘Jurema’, ‘Tepezcohuite’ | Seeds
We’re incredibly happy to boast that our latest EU exclusive is this amazing Mimosa hostilis ‘Inermis’ seed! Needless to say that we’ve very limited stocks of this rare, thorn-less to almost-thorn-less ‘Jurema’ variety, so be quick if it’s of interest to you… We also sell extremely fresh seed of the ‘standard’ Mimosa hostilis species type (harvested in late October 2018 in Spain) and also another which originates from a 2018 collection in Brazil.
A culturally and economically important perennial shrub or tree species of the Fabaceae, Mimosa hostilis (syn. Mimosa tenuiflora) is native to parts of Brazil, Colombia, El Salvador, Honduras, Mexico, Panama and Venezuela. It’s a fast-growing species, which is commonly known by names such as ‘Black Jurema’, ‘Cabrera’, ‘Calumbi’, ‘Carbonal’, ‘Jurema’, ‘Jurema Preta’ and ‘Tepezcohuite’.
Generally occuring at fairly low altitudes (below one thousand metres) in USDA Hardiness Zones 9-11, the dark-brown-red-grey-barked hostilis quickly reaches approximately eight metres in height. Their thorny, fern-like branches support bright-green, pinnate leaves roughly five centimetres long. Attractive, sweet-smelling white-whitish flowers bloom between November and July (in the Northern Hemisphere) and September and January (in the Southern Hemisphere) and are usually four and eight centimetres in length.
Mimosa hostilis bark is the source of much-valued organic dyes, tanning agents (for the species’ high tannin content) and soap-making ingredients (due to its high concentration of lipids and saponins). It’s also a key component of many indigenous medicinal practices throughout Middle and South America, where it’s often used to treat burns and wounds, coughs and chest infections, tooth pain and assorted other ailments. The plant in general is also a useful fertiliser, soil-fixer and fuel, as well as a source of charcoal, timber, drought-fodder and more.
This is quite an easy plant to raise from seed for the average gardener, provided a few basics are observed. Younger, smaller Mimosa hostilis plants make an excellent addition to any garden, whether indoors or out. If planting outside, do so in USDA Hardiness Zone 9 or higher for best results. Maximise germination by using simple seed pre-treatment techniques (you can go either the scarification or the soaking route – refer to our Cultivation Guides for more information). Hostilis seed should normally germinate after two to four weeks at a temperature of between 10°C to 30°C (around 25°C is best) and – due to the hard coating of the seed – remain viable for many years. Once germinated, sow directly into the ground (space around five metres apart if so – they get quite large), or else plant in containers filled with sandy, mildly acidic to mildly alkaline soil. Sit them in 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 propagate from cuttings, once you have a mature plant or two – cut off roughly thirty centimetres of branch and put it in the ground to root.
We’re extremely glad to have got our hands on this Mimosa hostilis ‘Inermis’ seed, but would highly recommend ordering quickly if you want some for yourself – we’re really not sure whether we’ll be able to re-stock this item once the current inventory sells out!
