| Comments | Cut back mature clumps in July to reduce plant height. Won the Classic City Award 2009. Allan Armitage of the U. of Georgia said, "...'Henry Eilers' is a handsome and spirited lad, indeed. We were very much entertained by the scoop-petaled, yellow-orange flowers. This Rudbeckia adds a whimsical focal point wherever planted. Flowering time was midsummer, and 'Henry Eilers' was still flowering November 1. Another attribute of this plant is the foliage remained healthy and unscathed by any disease or insect pillage throughout the season." |
