Worth knowing

  • A famine food in Ethiopia's Konso district, preferred over other Arisaema because it tastes acceptable, cooks quickly and keeps. Flavum means yellow, for the flower. Wikipedia: Arisaema flavum

Arisaema (Araceae). The Asiatic species were received as dried berries in midwinter and germ. readily at 70 after WC for 7 d. The American species exhibited complex behavior. Germination is hypogeal in all species. The seed forms a corm and root system before sending up the single true leaf. This first true leaf is a single leaflet in A. flavum germ. 70(6/6 in 2-5 w) and 40-70(3/4 in 3rd w). A jacquemonti germ. 70(90% in 3-6 w) and 40(517 in 8th w)-70(117).

Start around February 22, 2027 for a May 3 last frost.

  1. Sow and cover

    Temperature: 70°F 21°C
