Symphyotrichum rhiannon is a perennialflowering plant that grows between heights of 15 and 60 centimeters (5.9 and 23.6 inches). It forms colonies from thin, long rhizomes, and blooms from September into November with flower heads that have 18–32 blue to lavender ray florets and yellow disk florets.[5]
Kauffman, Nesom, et al., formally explained the etymology of the species as follows:[4]
[It] is named in honor of Rhiannon Weakley, whose desire to rest during a field excursion led the authors to further investigate..., and also in honor of the original Rhiannon, a Welsh goddess figure....
Informally explained, Rhiannon Weakley was the toddler daughter of Alan and Allison Weakley. She needed a snack and a nap during the 2003 field excursion.[8]
"Rhiannon hadn’t had a nap that morning," says Alan Weakley, "and she had a little, ah, loss of composure." So the group plopped down to give Rhiannon a snack and a chance to rest. And there, growing all around, was [Laura] Mansberg's mystery aster.
