Dracaena aletriformis flowers grow in large, lax panicles from the tips of branches. The flowers are silvery white to yellowish green and sweetly scented, opening in the evening and remaining so through the night. The flowers are mainly moth-pollinated.

The perianth is tubular and six-lobed, the lobes recurving, the flower bisexual. The stamens are positioned high up upon the perianth segments, their filaments inflated. The ovary is ovoid. Flowering happens from late spring through summer.

Some green fruits are visible in the photo although most have dropped off already; the photo was taken in January. The fruits are globose, single- or two-lobed berries that become reddish orange when ripe and seen on the trees until mid-autumn.

Seed dispersal is performed by the many birds and field mice that eat the fruit. The seeds are rounded and bony (Coates Palgrave, 2002; Pooley, 1993).
