20cm, Byzantine Arum makes arrow-shaped, slightly glossy leaves and a greenish-white spathe with a puplish blush towards the base and a pale purplish-brown spadix. A rarely cultivated, fully winter hardy species from humus rich, slightly moist soils from Southern Balkans to Western Turkey. Easily grown in any rich, well drained soil in a sunny to partially shaded spot. Material raised from seeds, plants should show some slight variation in spathe color. IV-V.
