GENUS INDEX

GENUS CODE: BALDU
GENUS SCIENTIFIC: Balduina
GENUS AUTHORITY: Nutt.
GENUS COMMON: Honeycombhead
GENUS SUMMARY: A genus of 3 species, herbs, of se. North America.
GENUS IDENTIFICATION: Identification notes: The common name alludes to the honeycomb-like texture of the receptacle, made up of connected receptacular bractlets which surround the achenes. This condition is diagnostic of the genus, and can be seen even when the plant is in flower by stripping the flowers from the receptacle. Superficially, the perennial species resemble some Helenium (particularly H. pinnatifidum and H. vernale), but these bloom months earlier. The punctate leaves are very distinctive.

HORTICULTURAL
Plant Sale Text: Savanna honeycombhead is a native herbaceous perennial that is not often available in the nursery trade. It occurs in wet pine savannas, pitcher plant bogs, wet roadside ditches, and on seepage slopes in the southeastern Coastal Plain. Solitary yellow daisy-like flowers appear in the summer through fall atop tall, slender but erect stems. Savanna honeycombhead prefers moist to wet soil in full sun and would be a perfect addition to a sunny bog garden.
