This is our selection of plants that can stand some cold. Some will only resist to cool weather and light frost, but some others will take hard frost in colder climates. They are all very different but they deserve to be tried because all these tropical-looking plants have non tropical requirements. They will surely thrive outdoors in coastal Mediterranean climates or in a mildly heated greenhouse where frost does not occur.
Pale green leaves open up in tufts of fluffy fibres. A robust Dasylirion from high altitude desert regions in central Mexico that develops a short trunk, often holding multiple crowns of pale green leaves with frayed leaf tips. Native to dry areas of Oaxaca and Puebla, in Mexico.

2 years old, 20-30 cm tall. This Dioon is elegant and different, with a stout trunk and glowing blue arching leaves with "V"arranged leaflets. It was described in 2003 and it is also frost hardy. Seeds are hard to find and awfully expensive, but we got a few for our nursery.
