Most people meet amaryllis as a bulb in a box at Christmas. It is also a garden plant, in a narrow band of the country.
How amaryllis fits zone 7's season
Zone 7b's frost-free window runs about 198 days, from April 10 to October 25. Amaryllis 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.
Amaryllis is hardy in zones 7-10, so in zone 7b it stays in the ground through winter and comes back rather than being replanted. Allow about 1 ft of spread at maturity.
