Cystopteris bulbifera (bulblet bladderfern) is a low-growing rock fern (usually limestone) with creeping stems and narrow elongate deltate fronds which grow to 75 cm (30 in). C. bulbifera is unusual among ferns in producing bulblets along the fronds.

Endemic to eastern and central North America. Found from Newfoundland south to Alabama and west to Minnesota and Arkansas with outliers in Arizona, New Mexico and Utah.


Typically grows on moist shaded limestone cliffs but can be found on rocks or in substantially calcareous soils.


C. bulbifera is occasionally cultivated as a garden ornamental.
