Ephedra tweediana (Tramontana) - A interesting climbing shrub with dark green wiry thin flexible jointed leafless branches that, with support, can grow to 12 feet or more and then arch outward and down with a thick trunk that is fissured and twisted. In early spring months (March in Santa Barbara) appear the golden primitive male reproductive structures (all of our plants are male) which are attractive against the green stems. Plant in full sun to light shade and irrigate little to abundantly. We have never seen damage on this plant and it is likely hardy to below 15° F. In our garden we have trained this plant up on a 10 foot tall metal pipe which it has grown above and reach 4 feet wide – to keep it in bounds we power shear it back a bit every two years or so and it rebounds rapidly. In the Mildred Mathias Botanic Garden, on the campus of the University of California Los Angeles, this plant is grown without support and they note it to have a haystack-like form to 12 feet tall and wide. In Annie's Annuals catalog it is described as looking like "Cousin It" and it is noted that it will grow to 3 to 5 feet tall by 5 feet wide. It seems to have taken this form along the slopes of Putah Creek in the UC Davis Arboretum where a group has been planted as a large scale shrubby groundcover. However it is grown, this plant is sure to attract attention as it does when visitors see our large towering plant. Our thanks to Dylan Hannon, now the curator of the Huntington Garden Conservatory, who gave us this strange yet interestingly attractive plant in 1997. Dylan got his original cutting of this plant from the Mildred Mathias Botanic Garden. 

The information displayed on this page about Ephedra tweediana is based on the research we have conducted about it in our nursery library as well as from information provided by reliable online resources. We also include our own observations made about this plant as it grows in the nursery gardens and other gardens visited, as well how the crops of this plant have performed in the containers in our nursery field. We will also incorporate comments that we have received from others and welcome hearing from anyone with information about this plant, particularly if it includes cultural information that will aid others to better grow it.
