(This plant comes in a 3.5" pot. You will receive a very similar plant to the one in the picture. It may or may not be blooming at the time of your purchase. The plant is shipped in its pot to prevent any damage to the roots).
Origin and habitat: Huachuca Mountains, Arizona on the Mexican border as far south of south as the sierra Huachinera.
Description: Agave parryi var. huachucensis is an upland variant with larger growth of the widespread and variable Agave parryi. It is a compact freely-suckering rosette-forming succulent with broad short grey leaves with prominent brown terminal spines. It is more robust than the standard Agave parryi, with larger leaves up to 20 cm wide and up to 65 cm long, and the flower stem broader with larger flowers up to 75 mm long.
Cultivation and propagation: Agave parryi var. huachucensis is usually cultivated outdoors in rock gardens, in cactus and succulent gardens, as it is very cold hardy, withstanding temperatures as low as -20° degree Celsius. It suckers, but tends to be slow to sucker, so easy to keep control of. Because of its compact size, plus its low water use and low maintenance, it is considered a good landscaping plant for desert residential landscaping.
Growth rate: Slow to medium growing, but speeds up considerably given the best conditions.
Exposure: They do well in full sun or a lightly shaded area with afternoon shade.
