  A 🪵 superdense hardwood, very durable, with a dark grain.  In WWI, the wood from American walnut was highly valued for making airplane propellers and gunstocks.  Its 🪵 wood is currently valued for furniture and cabinets.

Juglans hosts caterpillars of 130 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.

This tree produces a ☠︎ toxic[?] substance juglone that prevents many plants from growing under or near them.   Our neighbors still cannot get 🍅︎ tomatoes to bear fruit in soil beneath their mature black walnut tree, after they cut it down!

✋︎ On the other hand, 🌾︎ turf grass lawn still seems to grow underneath.

Plants native to North America that are resistant to juglone (scroll down).

✋︎ On the third hand, back when my yard contained a walnut tree, before mowing or playing ⚽︎ football-soccer / 🥍 lacrosse / whatever, this author had to walk the lawn and kick any walnuts off to the side.
