Teucrium glandulosum 'Cedros' (Desert Germander) - A small subshrub with hummock shaped growth to 12-18 inches tall and wide with tightly branching stems holding narrow slightly lobed/toothed green leaves that blush a purple color late in the season and in spring the flower stems emerge like starbursts in all directions, holding the frilly white flowers with purple streaks for many months - seemingly it blooms year-round with strongest flowering in spring.
Plant in full to part sun in a well-drained soil and irrigate infrequently to occasionally. It is a drought tolerant plant that also tolerates mild frosts and is likely hard to around 25F. Deadheading old flowers will improve appearance. This is an attractive plant that is useful in the foreground with larger California native and other mediterranean climate plants or mixed in with a dry meadow planting.
Teucrium glandulosum is native to the Sonoran Desert in Arizona throughout Baja California and in California, where it has only been found growing in the Whipple Mountains in San Bernardino County along the Arizona border. It typically grows in rocky desert habitats and dry canyons. This plant came to us from the Santa Barbara Botanic Garden as SBBG 16-105 from a collection made on Cedros Island in Baja California in 2016. The name for the genus has several possible derivations but most likely it is from the Greek name Teucer, a king of Troy, who is said to have used the plant medicinally. The specific epithet comes from the Latin word 'gluten' meaning "glue" in reference to the sticky leaves of this plant and for this reason one of this plant's other common names is Sticky Germander. We put out our first crops of this plant in 2022.
The information about Teucrium glandulosum 'Cedros' displayed on this web page is based on our research conducted in the nursery's horticultural library and from reliable online resources. We also include observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments we receive from others and welcome hearing from anyone with additional information, particularly if they can share cultural information that would aid others in growing this plant. |
