The worst thing about raising everbearing raspberries would have to be an early frost, especially in colder, northern areas While ‘Heritage’ is the standard bearer for everbearing raspberries, ‘Polana’ is better as you go further north with late season fruit ripining up uo 3 weeks earliar than ‘Heritage’, offering you a long season of luscious, large, glossy red berries without the worry of losing them to frost just as they are hitting their prime. Tasty’ easy to grow and raspberries in July and again in late August… it’s a home fruit grower’s dream!!
