What is this plant?
That looks like Goldenrod, and will get plumes of yellow flowers in late summer into fall. Most consider it a weed, but pollinators love it.
Many people mistakenly believe that goldenrod causes allergies. Not so. It is the Ragweed that blooms at the same time, with flowers that are barely noticeable that makes people sneeze.
Some of these are 6 or 7 feet tall. Can goldenrod get that big?
There are many species of golden rod, and, yes, they can get very tall.
However, for an exact id, please send us photos after it flowers.
