CYSTOPTERIS BULBIFERA SIS-top-TER-IS Zones 4-9 Berry Bladder
CYBU - This small fern grows about 1' tall and is finely divided. Lacy. It does not spread by underground rhizomes, and we like that feature. Little bulblets or "berries" are produced on the back sides of the fronds. These fall off and produce new plants. This fern does not "brown out" in late summer. Spring only.
