I don't think it's an alpine. It has put out a few runners over the four years I've had it. Like, six maybe? The longest one was about 8" long. The crappy strawberries planted in the same bed and equally abused put out endless amounts of very long runners.
Seascape sounds like a good variety to try out, even if it's not what I have. I suppose I
should just be looking for good varieties to try, regardless of what I have already.
