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.
Looks like a smaller sized relative of Alocasia macrorrhiza, but leaf margins are by far more undulate (wavy). The whole plant will hardly grow above 1-1,5 m in height, while macrorrhiza can easily grow more than 3 m. This smaller species is native to the Kachin Hills in the North of Myanmar.
This plant produces huge leaves that can attain 1,5 in a short time. It is a must for tropical-looking gardens but it can take quite a few degrees of frost. It grows well in the coastal mediterranean, with wind protection and abundat water. The stem has some itchy sap but it is edible if cooked for a long time.
"Hardy Elephant Ear" is a species of Alocasia that can take cold much better than others. It is native to high elevations in New Guinea. Leaf blades reach only 30-40 cm but they are purple-coppery beneath. It is fast growing, it does not require hot conditions and will sprout back after mild frost.
Cold-hardy hybrid of unrivalled beauty. It is a man-made cross of Alocasia odora x Alocasia portei, developed in Florida. It bears magnificent huge leaves, and will survive to frost, to about -10 C. Leaves can reach 1.5 m in length and trunks can grow up to 2 m tall, giving a palm-like appearance.
Thick 15-20 cm 1-y old rooted plant - It is a spectacular species, relative of the genus Aloe with leaves arranged as fans. Kumara plicatilis grows as a shrub or small tree and thrives outdoors in the coastal Mediterranean. It blooms in winter and its flowers are much larger than most aloes !
Robust plant, 30-40 cm, 1 kg, field-grown in full sun. This is the famous Aloe vera, known for holding healthy properties. The tips of the tall flower spikes are edible. Leaves are green-glaucous to pink-copper. Takes light frost if kept dry.
This is a cool-growing species of Alpinia, which is possibly the frost-hardiest in the genus. It is similar to Alpinia zerumbet, but shorter in stature with wavier leaf margins. Our rhizomes are uprooted from adult, blooming, mother plants. This ginger is also used medicinally.
Hard-to-find Japanese selection of "variegated" Aspidistra. It is not striped: each leaf develops a cream white "shade" in the upper part of the blade. Aspidistras make excellent pot plants for shade. They can live indoors or outdoors as they can take real frost.
