How basket-of-gold fits zone 5's season
Zone 5b's frost-free window runs about 148 days, from May 10 to October 5. Basket-of-gold takes about 1 growing season to reach full flowering, so what matters here is how many of these seasons it gets, not whether one is long enough.
Basket-of-gold is hardy in zones 3-7, so in zone 5b it stays in the ground through winter and comes back rather than being replanted. Allow about 1.5 ft of spread at maturity.
