Agave Isthmensis Variegata often called Parry’s agave or mescal is most noted for its attractive blue-gray to gray-green evergreen leaves but is also noted for its infrequent but spectacular flowering spikes. Thick, rigid, smooth, ovate to oblong, blue-gray leaves (to 12” long) form a large, dense, symmetrical, basal rosette. Each rosette will flower only once, usually at some point between 10-15 years. One huge flowering stalk (to 20′ tall) will rise from each rosette, with each stalk producing 20 to 30 side branches and with each side branch containing a large cluster of creamy yellow flowers. In its native habitat, flowers typically bloom in summer (June – August).
Planting & Caring –
Best growth occurs in a sandy/gritty, dry to medium moisture, well-drained soil in full sun. Tolerates some light shade. Sharp soil drainage is important. Poorly-drained soils inevitably lead to root rot. Tolerates dry soils and drought. Surprisingly good winter hardiness for this succulent.
