The flowers of Watsonia aletroides grow in a two-sided, erect spike that is lax or loose and rarely branched. There may be up to 20 flowers in one inflorescence.
The nodding or pendulous perianths are narrowly cylindrical tubes that bend down near the base. The corolla tubes become up to 4,5 cm long.
The small tepals are red, red-orange or pink-purple, often with white at the corolla tip. In the picture only the inner three tepals are white-tipped (Mustart, et al, 1997; Manning, 2007; Bond and Goldblatt, 1984).
