When to plant amaryllis in zone 7b
Zones 7a and 7b share the same average frost dates in our data, so this page covers both.
Method: Direct sow: Direct-sow outside. Amaryllis doesn't transplant well, or doesn't need the extra time indoors.
| Start indoors | Not typically started indoors |
|---|---|
| Direct sow / transplant outside | Apr 17–Apr 24 |
| Estimated bloom | Apr 16 '28–Apr 23 '28 (First real harvest the season after planting) |
Spacing: 1 per square foot (square-foot-gardening spacing). Mature height: 1-3 ft.
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.
