    This is the first year these have appeared in our native garden. Never seen anything like them and all my usual attempts to identify have failed. The plants are 12-15' (yes FEET) tall! Foliage is 12" - 15" long and leaves are very narrow.
    Any help will be appreciated.

    You don't say where you live. Maybe maximilian sunflower or giant sunflower. Both are wildflowers that bloom now.

    Really does look like Helianthus salicifolius as suggested.

    I was leaning towards a Coreopsis tripteris . Typically they grow to about 8 feet tall, but I had some a couple of years ago that grew up to 10+ feet tall.

    But it could be the Helianthus salicifolius.

    Thanks for all the suggestions. We live in eastern Missouri, just west of St. Louis.
    After looking at the possibilities presented, we're certain it is a willow-leaved sunflower (Helianthus salicifolius.)
    Never heard of this, nor seen before, but we have a substantial "patch" of them now, right next to our Cup plants (Silphium perfoliatum.)
    Thanks again, you guys are AWESOME!

    If you ever plant purchased wild flower seed,, odd things can show up ! Sometimes a year or two later.
