Eucalyptus in Zone 2a & 2b
Eucalyptus pulverulenta
Yes, eucalyptus grows in zones 2a and 2b. Start seeds indoors Mar 18–Mar 25 and plant out May 27–Jun 3.
When to plant eucalyptus in zone 2b
Zones 2a and 2b share the same average frost dates, so this page covers both.
Method: Start indoors: Start indoors from seed, then transplant outside. It needs a head start most zones can't give it by direct-sowing alone.
| Start indoors | Mar 18–Mar 25 |
|---|---|
| Direct sow / transplant outside | May 27–Jun 3 |
| Estimated bloom | Sep 4–Sep 11 (~100 days after transplanting) |
Spacing: 1 per square foot (square-foot-gardening spacing). Mature height: 2-4 ft.

Zone 2 sows before zone 3 here, which looks wrong and is not. USDA zones rank winter cold, not season length, and zone 2 is mostly interior Alaska, where hard winters come with warm summers. More on what a zone measures.
