(Ethnobotany database)

Nyssa hosts caterpillars of 30 species
of butterflies and moths, in some areas.
  This plant is also known to be a host for (in areas where invasive) 🐝︎ spotted lanternfly (SLF)  Lycorma delicatula.

In its native area, recommended as a specimen tree.   Way cool, loved by many of my buddies (and uncommon enough that it really stands out), gives great red 🍃︎ autumn color, and visual interest in other seasons.  Adapted to wet sites.  Slow growing, but totally worth the wait.  Transplanting can be difficult, except in the 🌱︎⚘ spring.
