Agave murpheyi · Asparagaceae (Agavoideae)
Also called: Hohokam Agave, Murphey Agave, Murphey's Century Plant
Murphey's Agave (Agave murpheyi) is a very low-water accent native to the Sonoran Desert region well suited to Tucson and the low desert. It thrives in full sun to partial shade.
Murphey's Agave at a glance
- Water use
- Very Low (established)
- Sun
- Full sun to partial shade; tolerates reflected heat well and also grows under desert tree canopies.
- Mature size
- 2-3 ft H x 2-4 ft W (rosette); flower stalk 8-15 ft H
- Growth rate
- Slow to moderate; offsets freely (and produces bulbils) to form colonies; flowers at roughly 8-15 years.
- Bloom
- Pale green to yellowish-green flowers, often flushed pink/red in bud; produces bulbils on the stalk, Late winter to early spring (often February-April), notably earlier than most agaves; frequently sets bulbils rather than viable seed.
- Cold hardiness
- Cold hardy to about 10-15 F (USDA zones 8b-10); well adapted to low- and mid-desert temperature swings.
- Soil
- Well-drained rocky, sandy, or loamy desert soils including caliche; very tolerant of lean native soils. Good drainage essential.
- Native range
- Southern/central Arizona and northern Sonora, Mexico, where it occurs almost exclusively at ancient Hohokam archaeological sites. A pre-Columbian domesticate cultivated and spread by the Hohokam; persists as living clones from cultivation around AD 600-1450.
- Best used as
- Specimen/accent plant, Xeriscape and revegetation plantings, Heritage/ethnobotanical and pollinator gardens, Mass or colony plantings, Container culture
- Wildlife
- Early bloom provides important late-winter nectar for hummingbirds, bees, and bats; historically a major human food and fiber crop (rosettes pit-roasted for sugars).
- Toxicity
- Raw sap contains saponins/calcium oxalate and is irritating to skin and toxic if ingested raw; marginal teeth and terminal spine can injure. (Traditionally rendered edible only by long pit-roasting.)
How to grow Murphey's Agave in Tucson & the low desert
Watering
Extremely drought tolerant once established—supplemental water is rarely needed; a deep soak once a month in the hottest, driest part of summer keeps it looking lush. No winter irrigation.
Fertilizer & nutrients
None required; thrives in unamended desert soil. Avoid fertilizing, which can cause floppy, etiolated growth.
Pruning & care
Remove dead/damaged leaves and the spent flower stalk. Thin offsets to manage colony spread. Monocarpic rosettes die after bloom; offsets carry on the clump.
Notes
A culturally significant 'living legacy' plant—an early-blooming, broad-leaved gray-green agave with a cross-banded leaf pattern, rarely setting seed and reproducing mainly by offsets and bulbils. One of very few true Arizona-associated agaves; its distribution reflects ancient Hohokam cultivation rather than natural seed spread.
