Gram-positive rods, 0.8 x 1.5-7 µm, occur as single cells, in pairs, or in chains.
Nonmotile.
Facultatively anaerobic. Colonies on FYP agar are beige, smooth and 1-2 mm in
diameter after incubation for 3 days under anaerobic conditions; surface growth under
aerobic conditions is poor.
Grow at 15 ºC. No growth at 45 ºC. Grow in 5% NaCl. Range of pH 4.0-8.0.
Isolated from  peony (Paeonia suffruticosa) & bietou (Chrysanthemoides monilifera) flowers  collected at Western Cape, South Africa.
Undetermined.

Homofermentative.
