Syagrus romanzoffiana Litoralis
Robust Queen Palm, Silver Queen Palm
A robust cultivar of the Queen Palm from Argentina, Uruguay and Southern Brazil, where it is found to over 1000 m (3300 ft.) altitude, with a thicker, sturdier trunk that supports a compact crown of arching leaves with particularly thick and wide leaflets. It is very hardy to cold and is said to survive temperatures down to -9°C (15°F) undamaged. Apparently this palm has already been in cultivation in the U.S. for a while, most popularly under the name Silver Queen. Reportedly, the palm received that name in Florida not because its leaves or any other of its parts are silver, but rather because after a hard freeze that killed all the more tender Queen Palms, the ones that survived, the Silver Queens, had leaflets that appeared in a strange, translucent silver tone in sunlight, the result of a light frost damage.
