How basket-of-gold fits zone 4's season
Zone 4b's frost-free window runs about 128 days, from May 15 to September 20. 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 4b it stays in the ground through winter and comes back rather than being replanted. Allow about 1.5 ft of spread at maturity.
