Echeveria olivacea (Macdougall's Oaxacan Echeveria) - A short-stemmed succulent with flattened rosettes to 4 inches wide with 2 inch long olive-green, red-tinted, elliptical-shaped leaves. An erect inflorescence 8 to 20 inches tall bearing stem leaves the same shape and color as the rosette leaves is topped by an elongated simple spike of yellow blushed-orange to red flowers. Plant in full coastal sun to light shade in a well-drained soil and irrigate occasionally. Cold hardy to 25 F. (Note – this plant is new to cultivation and we are still learning the tolerances of it though it comes from tropical dry forest so it is likely that the plant can tolerate prolonged dry periods. We had a plant outside during the January 2007 cold spell and it remained unaffected by short-duration temperatures down to 25 F.) This plant was originally discovered by botanist-explorer Tom Macdougall in 1963 and published much later from photos and old data by Reid Moran in Mexican Cactus and Succulent Journal in 1991. The plant was included in John Pilbeam's book “The Genus Echeveria” (British Cactus and Succulent Society, 2008) as in the group Racemosae with a note that it may be more appropriate in the group Spicatae and that future DNA work on this rediscovered plant may help determine where this plant belongs.
The information about Echeveria olivacea that is displayed on this web page is based on research conducted in our nursery's horticultural library and from reliable online resources. We will also include observations made about this plant as it grows in our nursery gardens and other gardens that we have visited, as well how the crops have performed in containers in our nursery field. We also incorporate comments that we receive from others and welcome hearing from anyone with additional information, particularly if they share cultural information that aids others growing this plant.
Please note that after 46 years in business, San Marcos Growers will be discontinuing nursery operations by the end of 2025 and the property will be developed for affordable housing.
