I have had Mignonette for several years. I like the berries, but mostly I have them because they do well as landscape plants here in partial shade and reseed like crazy. They’re the most cost effective groundcover for certain parts of my yard.
But I started growing several other varieties from seed last year. The plants are doing well, but they haven’t produced berries yet. Again, I didn’t plant them with eating the berries as the primary objective. I planted them to cover the bare soil in the containers where I grow my culinary ginger, turmeric, and galanga.
I ordered the seeds from the Strawberry Seed Store. They had a good variety of seeds for some of the more unusual strawberries and the service was very good.
