Looking for a hardy, drought-tolerant plant that can grow in poor soil? Look no further than Argemone mexicana, also known as Mexican Pricklypoppy or flowering thistle. This plant, native to Mexico, is well-suited for new road cuttings or verges, where it can be the only cover available. Despite its toxic alkaloids, it has been used medicinally for centuries in traditional Hispanic and Native American cultures, including as a sedative and analgesic tea and as a treatment for warts, cuts, and skin diseases. Biodiesel production from its seed oil has even been demonstrated. Sow the seeds in April in situ, and watch this hardy pioneer plant grow!
