The Alpine strawberries keep strawberrying. Luckily, the squirrels are not interested in them, despite their strong and delicious perfume (the strawberries', not the squirrels'). If you have the space for a long row, plant them, and gather more than my twice-weekly breakfast handful from three small, six-inch pots.
Two of these tough little plants survived our last winter, and one grew from seed, from last year's dropped fruit. They were puny in April and are now plush and prolific (p-p-p-p!).
