Zones

Question

I live in Zone 8b. If plants/trees suggest they grow best in Zone 2 to 7, would that be a bad choice for Zone 8?

Answer 1

A range of 2-7 implies that a zone warmer than 7 may be too warm in winter for the plant to thrive. The second number, as in 2-7, indicates that the plant needs cold-induced dormancy to trigger spring growth and blooms. So, if grown in zone 8, it may not flower. To double check, search the internet for the plant's heat zone. Confusing!
