Prionium
Prionium is a monotypic genus. Prionium is a robust, evergreen, semiaquatic, rhizomatous flowering plant growing to 2 m in height. The stem of P. serratum is up to 10 cm in diameter and covered with the black, fibrous bases of old spirally arranged leaves, four-ranked or tristichous. The strap-like lanceolate leaves are rigid, narrow, leathery, grey-green, and with toothed margins. The small, brown flowers are on a branched inflorescence. Plants are hermaphroditic and pollination is anemophilous. The fruit is a dry dehiscent triangular capsule, with three seed chambers and arillate seeds which are hispid (with sclerenchymatous fibres) and winged. The net-like, black fibrous, reticulate leaf sheaths are often found on beaches near rivers with colonies of palmiet. New flower shoots are cooked as vegetables. Prionium is endemic to South Africa.

Water: Adapted to intermittent hydration, prionium thrives in environments with sporadic rainfall, requiring watering every 2-3 weeks. Its growth cycle aligns with seasonal patterns, making it a resilient choice for water-wise gardens.
Propagation: Propagation of prionium is primarily through seed sowing under moist soil, partial sun, and moderate temperatures. To aid germination, pre-soak seeds for 24-48 hours, sow in well-draining soil, maintain moisture, and transplant robust seedlings when ready. The process is moderately difficult due to seed toughness.
