Cornus canadensis Observations
(bunchberry)
Submit Data Observations
Introduction to the NPN Native Species Observation Program
Bunchberry (also known as crackerberry or dwarf cornel) is a low, erect woodland plant (about 10 cm tall) that grows in colonies, and tolerates a variety of soil and site conditions. It has smooth-edged oval leaves with parallel veins; and four to six leaves form a ring around the stem. Each plant has a single cluster with four showy white bracts that look like petals, which are tiny and either green, purple, or cream-colored. The fruits are red berries that appear later in the summer.

You should record when two well-defined phenological events occur for bunchberry:
- First bloom (FB) First select an approximately 1 by 1 meter plot for observation, and then record the date when first flowers are open in at least three places on the observed plants.
- Mid bloom (MB) Within the same 1 by 1 meter plot used for first bloom, this is the date when 50% of the flowers are open on the observed plants.
