I recently moved and the spring/early summer in New England has been a chance to figure out what previous residents planted. One I have yet to identify is this plant:
About 15 popped up in a south facing bed. Very straight up and down. At first I thought it might be a tomatillo, but the leaves don’t look quite right, nor is it really bushy like many I’ve seen.
Does anyone have any idea what it might be? Hardiness zone 5, northwest CT, USA.
