Gardeners' Notes:

Rugen Improved is a great alpine strawberry. It's very hardy and survived my zone 7 winter in a pot. When the weather warms up, it comes back to life from a seeminly dead plant and turns green again and sets little white flowers. The flowers turn into very sweet tangy fruits in early summer and will produce fruit until weather starts to become cold.

I'm not sure of spreading or reseeding habits because I have not planted this in the ground. I keep it in a pot year round in full sun and I water when the soil is dry on top.

"Surely God could have created a fruit better than the strawberry, but equally surely, He didn't."

This variety has the best flavor of all strawberries that I have tasted. They are very small, though, and must be grown under good conditions for the best flavor. 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 heaved out of the soil.
