No, he’s not the star of the September Garden, but Boltonia ‘Nally’s Lime Dot’ should be a nominee for best supporting actor in the mixed border. He’s a curiosity, for sure, with his loose sprays of 1/4″ green disk flowers, but one can’t help but notice how his little green buttons enhance the other plants around him, whether in the garden or in a vase.
Boltonia asteroides ‘Nally’s Lime Dot’ is in the Aster family (Asteracea) and was selected by a Mr. Nally, thus the name, who noticed how all the flowers presented were minus the typical white ray petals. ‘Nally’s Lime Dot’ has a tendency to get too tall (5-6′) and flop over with the weight of his blossoms, unless he is cut back in mid summer. (We usually do this by mid July, and then plants grow to a sturdier 4-5′.) He looks quite appealing in the garden paired with Smooth Aster (Symphyotrichon laevis ‘Bluebird’) or in a vase with a bouquet of Dahlia. ‘Nally’s Lime Dot’ grows well in full sun or perhaps a little shade, and will readily form easily divided clumps. The hardiness range is zone 5 -8 (possibly zone 4 we’ve heard, but can anyone confirm that?).
