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.
Blue flax-lily or blueberry is a perennial ornamental from Eastern Australia and Tasmania, with glossy green blade-like leaves to 70 cm long. Blue flowers are produced in spring and summer and purple berries are kept througout autumn. It is hardy to drought, snow and frost, to at least -7 C.
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.
Grafted tree. Spanish cultivar with very large, smooth, juicy fruits of "Japanese loquat", with a pale colour. The perfect fruit tree for the home garden, with sweet and acid fruits and very ornamental foliage. Fully hardy to about -7 C but also survives to about -17 C.
A classic of subtropical gardening. This is one of the cold-hardiest coral-trees and it is quite easy to grow and bloom, with fabulous sprays of large coral-red flowers. It can be a small shrub to a tree of 10 or more meters in height.
