When to plant black-eyed susan in zone 2b
Zones 2a and 2b share the same average frost dates in our data, so this page covers both.

Spacing: 1 per square foot (square-foot-gardening spacing). Mature height: 2-3 ft.
Black-eyed Susan is one of the few flowers that rewards low effort in a way that feels almost unfair. Sow it, keep it in the sun, ignore it. It germinates readily, flowers in its first summer, and carries on through drought and heat that has the rest of the border sulking, standing 2 to 3 feet tall with the classic golden-yellow daisy petals ringing a raised, dark brown-black center.
How black-eyed susan fits zone 2's season
Zone 2b's frost-free window runs about 104 days, from May 20 to September 1. Black-Eyed Susan needs about 70 days from sowing to first harvest.
