Giant Aquatic Arrowhead is native of tropical Africa (Tanzania to Madagascar, and Comores). It grows as a perennial making an impressing tall banana-like pseudo stem and up to 150cm long, large arrow-shaped leaves. In cultivation this plant requires a bog-like position and a minimum of 20°C (the optimum are some 25°C) throughout the year in a sunny spot.
Place the large seed horizontally on an humus rich soil, cover the seed only slightly with soil. Cover the soil (pot has to be without drainage holes) with some 2cm of water. Will germinate rapidly at some 25°C in a sunny spot. The first leaves are more or less lance-shaped and will gradually extend to the typical arrow-like form.
The price is given per two (2) large seeds.
