10 Mimosa Hostilis tenuiflora Seeds, 'Jurema' plant, Calif.
Limit one per person.
Seeds do not contain alkaloids. Genuine Mimosa hostilis Seeds from San Diego. A tropical, fast growing, thorny vine. Super fast grower, can grow an inch per day. A US best seller, but will not grow outside semi-tropical areas without winter cover. Phalaris is a good alternative for most of the USA. Not suitable as a house plant unless you don't mind thorns or like to clip the little buggers. Greenhouse or protect from frost. Even slight frost can kill an entire plant. Prefers temps above 60F at all times. It prefers a humid environment with temps around 80F. Established plants are a bit more frost resistant, but best to cover like any other tropical.
Special Germination Instructions:
Improve germination three to six fold by mimicking the effects of a forest fire. Seeds lie dormant for years waiting for a forest fire event. Germination is only 15% without scarification, OR, over 90% with proper seed scarification. So always do the following:
Mimosa seeds need fire scarification.
Place seeds in a jar with wood smoke for four hours, then pour hot water (150-199F) on the seeds for two minutes (you can skip the smoke, but not the heat treatment). Do not put seeds into boiling water. Plant in rich, warm soil with a bit of wood ash, keep humidity high (use a humidity dome if needed), and water daily. Once sprouted, remove the humidity dome to prevent damping off and mold issues; keep air moving.
Afternoon shade or filtered light is best. A tall trellis or scorched trees may needed for support, but can be pruned into many shapes.
Vines can grow an inch per day. NO FROST! Tropical plant with thorns.

Photo Notes: One photo of the mimosa stem is from a plant that I grew. The mimosa hostilis tree is from a WBTC customer in Texas who grew this five-year-old tree from one of my seeds, the one surviving plant from a pack of 20 original seeds. He said it has survived several frosts and a major hurricane. It flowered in the fifth year. Mimosa can be pruned to adapt to different shapes and environments, into a trellised vine or a compact bush or even a small tree. Normally they climb straight up.
