| Hey, there, gramNH - Since you bumped this up from last season, I've got some new, REALLY BIG, news: someone else here on GW tipped me off to a HUGE ironweed, fully 12-foot tall(!), called Vernonia altissima 'Jonesboro Giant', available at Plant Delights Nursery, a top-drawer outfit in North Carolina. Of course, I MUST have one - so check next year and I'll report what happened. . . By the way, my regular V. novaboracensis has done just fine with a very heavy mulch, and the several grasses in front of it keep the roots shaded - no special watering. . . Cheers, Carl P.S. There's no way I have all the answers - we must both just like the same plants! :-) |
