A curious genus of Aroids spread from Portugal and Morocco as far east as Afghanistan. They are related to Arum but Biarum leaves lack lobes at the base and so are spear-shaped; Arum has lobed, arrow-head shaped leaves. Biarum have whitish berries each with one seed, Arum have 2-6 seeds per red berry.
Most are autumn flowering but they can bloom in April (B. spruneri), July (B. ditschianum), and October (B. davisii and B. marmarisense). The inflorescence is similar to Arum but is on a short stem, close to ground level. Some are pungently smelly for the first day after opening when the female flowers are fertile. By the second day the smell eases and the male flowers become fertile. Some are unscented, a few are delightfully perfumed.
All of the species that we offer follow a Mediterranean pattern of growth. All are dormant over the summer months. They can be easily grown in a soil-based compost. Keep dry in summer, growth starts in autumn. Most don't like cold. but tenuifolium can be grown outside in favourable parts of the UK. We have overwintered marmarisense down to -10°C without harm, but in general I prefer pots in a frost-free glasshouse, or bedded out in the same house.
