American Elm (Disease-Resistant)
Ulmus americana
Family Ulmaceae
Before Dutch elm disease, American elms arched over Main Streets like cathedral naves — and thanks to resistant selections like Princeton and Valley Forge, that vase-shaped canopy is plantable again. Same graceful arch, same fast growth, same green tunnel effect, now with the disease answered.
It remains what it always was underneath: a tough, adaptable native that handles city streets, hosts butterflies, and feeds wildlife with its papery spring seed. The single rule is to buy only the named resistant cultivars. Do that, and you can plant a piece of restored Americana.

The iconic arching 'cathedral' street tree that Dutch elm disease erased from American Main Streets — now returning through disease-RESISTANT cultivars ('Princeton', 'Valley Forge', 'New Harmony') that recapture the graceful vase shape while surviving DED. Fast, adaptable, tough in wet or dry and urban conditions, and a butterfly host. Only plant the resistant cultivars; seedling elms still succumb.

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.
- Harvest — picking time — check ripeness every few days.
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.
