Overview

Manfreda spp. is a genus of about 30 succulent perennials in the asparagus family (Asparagaceae), native to Mexico and the southern United States and known as false agaves. Unlike true agaves, the plants carry soft, fleshy, mostly unarmed leaves that arise from a fat underground tuber, and most go dormant in winter. Rosettes are typically 6-18 in (15-45 cm) wide, with lance-shaped leaves 6-24 in (15-60 cm) long that are frequently marked with reddish-brown or purple spots. In summer, a slender flower spike rises 3-6 ft (0.9-1.8 m) above the rosette, carrying tubular greenish, brown, or maroon flowers with long protruding stamens; many are night-scented and draw moths and bats. After flowering, the rosette persists and offsets to form colonies. Plants store water in the tuber and tolerate drought but rot in cold, wet soil. Hardiness varies widely, with some species tender and others root-hardy into temperate gardens.

Native Range

Manfreda spp. ranges from the southern United States, including Texas and parts of the Southeast, through Mexico to Central America, where species grow in grasslands, open woodland, rocky hillsides, and scrub. Several are restricted to limestone soils or seasonally dry habitats.

Suggested Uses

Manfreda spp. is grown in rock gardens, gravel and dry borders, succulent containers, and as a spotted-leaf accent among low plantings. Rosettes are spaced 12-18 in (30-45 cm) apart to allow for offsetting. The night-scented flowers suit evening gardens and pollinator plantings.

How to Identify

Identify Manfreda spp. by its soft, fleshy, usually spineless leaves, often spotted purple-brown, emerging from a thick underground tuber, in contrast to the stiff, armed leaves of true agaves. A tall, slender, mostly unbranched spike of tubular flowers with long exserted stamens appears in summer. Most species die back to the tuber over winter and reappear in spring.

Bloom Information

Bloom Period

~4 weeks

Summer

Flowering occurs in summer, generally June to August, on a tall spike well above the rosette. Tubular greenish to maroon flowers open over several weeks, many releasing scent at night to attract moths and bats. Capsules with flat black seeds follow, and the rosette survives after blooming, unlike a true agave.

Care & Maintenance

Care Guide

Manfreda spp. grows in full sun to part shade in gritty, sharply drained soil with a pH of 6.0-7.5, and needs little water once established. The leaves take some shade better than most succulents, though flowering and leaf spotting are stronger in sun. Wet, cold soil rots the tuber, so winter drainage matters more than minimum temperature. Hardiness ranges from USDA zones 7-11 across the genus, with tuberous species surviving cold where soil stays dry. Plants spread by offsets and are lifted and divided in spring if colonies crowd. Container culture in cactus mix suits gardeners in wet-winter climates.

Pruning

Manfreda spp. needs no pruning beyond grooming. Spent flower spikes are cut to the base after the seed capsules ripen, and dried or damaged leaves are removed as the rosette goes dormant. Offsets are separated in spring to manage spread.
