Hackberry
Celtis occidentalis
Family Cannabaceae

There's a native shade tree that thrives where nothing else will — drought, wind, road salt, compacted city clay — and still feeds the neighborhood. Hackberry hangs small, sweet, date-like berries that birds strip bare, a genuine wild edible people have gathered for centuries. It isn't glamorous. It's indestructible, and generous.
Several butterfly species raise their caterpillars in its canopy, so a single tree quietly runs a nursery all summer. Hardy from zone 3 to 9 and reaching 40 to 60 feet at a decent pace, it's the tree for the worst spot on your property — plant it there and stop worrying.

What each band means
- Bloom — flowers open — pollinators working, frost on blossoms is the danger.
- Prune — shape it now — cuts heal cleanly and structure is visible.
These are the species' typical months — expect them a few weeks earlier in warm zones and later in cold ones. Watch the plant, not just the calendar.

One caveat on this one: Berries edible and safe. Never eat a plant you haven't positively identified, and check with a vet before letting pets or livestock graze anything new.
