Currently at Bunnings, Rothwell there are 4 varieties of Strawberry plants. Single plants in pots and being commercial varieties, I assume they will produce runners.
There's Bunyarra, Red Gauntlet, Sweetie and Tioga. They are new varieties to me and will join their Redlands Joy compatriots. I have no idea how they will perform - RJ is OK but not spectacular. Much subject to some mildewy-type disease and soft fruit rots. Although a lot of that could be from incorrect or insufficient nutrition (blush).
Anyway, at $2 each they are a fairly cheap way of getting some new genetics into the garden. Although they probably won't give much fruit this season, they will be ready to make plenty of runners for next season.
I have found that the best crops are from the runners - no doubt this is a good reason for commercial growers to re-plant each season. Soil-borne diseases with monoculture following monoculture would play a part commercially, too.
Sometimes following the plant-cultural practices of commercial growers yields best results - growing Tomatoes single-stemmed is one example.
