About
Seiou is a titanota variant raised at a nursery in Taiwan and named by a trader. According to a Japanese succulent encyclopedia, its teeth are white and broad, and it stays compact at about 15 cm across even when mature, a crafted-looking plant that shows off its white teeth. It is romanised SEIOU and sometimes abbreviated SEO. Whereas titanota rosettes generally range from 30 to 90 cm across, Seiou stays small with white teeth packed closely along the leaves, which sets it apart. Tissue-cultured plants are also in circulation. Plants traded as titanota also include what has recently been described as A. oteroi, and the classification is not settled. In Japan it is handled by specialist nurseries and auctions. Care is the same as for other titanota: strong light, good airflow and a dry regime keep the leaves compact and true to form. Being naturally small, keep it in a modest, free-draining pot so it is not weakened by root crowding or excess moisture.
