Agave americana flowering stems

The tall inflorescence of Agave americana grows only once from each leaf rosette. It consists of numerous horizontal panicles of flowers spaced up a sturdy stalk, a pole of up to 8 m tall. It may take a plant ten to thirty years for the towering flower spectacle to emerge.

Individual flowers grow clustered in strong-stalked tiers spaced around the central stem. The pale-yellow to yellow-green flowers are tubular, aromatic and rich in nectar, each formed by six tepals. There are six narrowly oblong, bilobed stamens, yellow and far exserted above the corolla. A single, greenish style tapers above the ovary in each flower. Bloomtime is summer and autumn.

The leaf rosette dies after producing one such flowering display. As in the photo, the impressive, erect, post-floral structures remain standing for long when the flower colours are gone. Seeds ripen inside the hardening capsules as the leaves below slowly die (Euston-Brown and Kruger, 2023; Van Wyk and Gericke, 2000; iNaturalist; Wikipedia; https://planetdesert.com).
