Of the 1,000 banana varieties in the world, only one tends to show up in supermarkets. Luckily these handsome broad-leafed plants thrive here in frost-free areas, giving San Diego gardeners a chance to savor homegrown fruit, some with tasty overtones of apple, mango or papaya. Master Gardener Carol Graham, a banana expert, suggests "cold-hardy” ‘Orinoco’ grown in California for decades, Honduran-bred ‘Sweetheart’, ‘Cardaba’ ideal for cooking, and ‘Cuban Red’, one of the exotic red-skinned varieties. Plant them in full-sun and provide regular water in well-draining soil. Wind damage to leaves- think of it as fringe, Graham says - won’t inhibit fruiting which generally occurs within two years after planting.
