Other names and notes
(Parasol Aster) Small flower heads (1/2 to 3/4") with 7 to 14 white rays growing atop tall stems, 3 to 6 feet high, in a flat-topped cluster. Leaves are lance shaped, much longer than wide, toothless and stalkless, tapering at both ends and are 4 to 6times longer than wide. The plant prefers moist soil and is one of the earliest blooming asters in the Woodland Garden along the bog trail. This aster, like many others, have recently been reclassified by botanists into other genera. The old species name, umbellatus, referred to the umbrella-like flower heads.
