Rugen Improved is a great alpine strawberry. It's very hardy and survived my zone 7 winter in a pot.

The plant does best if it receives light afternoon shade, but that does reduce flowering and fruiting in the summer. Too little water makes the fruit hard, while too much water makes the flavor insipid.

This strawberry is runnerless, but the crowns increase through the years, and can be divided periodically to increase the supply.

Flowering and fruiting begins in April, and continues until frost in the fall. Plants should be mulched in the winter to prevent the crowns from being he... read more
