Native to (or naturalized in) Oregon:
- Deciduous tree, 20-30 ft (6-9 m), spreading, ascending branches, flattish top. Leaves alternate, simple, 7.5-13 cm across, heart-shaped (cordate), margin entire, conspicuous swelling just below blade, lustrous dark green color; fall color is usually mixture of pale green and yellow, although occasionally bright yellow to even golden. Small (13 mm) rosy-pink flowers in spring before leaves appear, some produced on older limbs. There is also a white flowered form, var. alba. Fruit is a flat pod, 5-7.5 cm long, about 1.25 cm wide, green, finally brownish black, fruit set may be heavy and fruit persist through winter.
- Sun to part shade. Does well in many soil types, except permanently wet, adaptable to acid and alkaline.
- Hardy to USDA Zone (3) 4, some variation. Native range from New Jersey to Florida, west to Missouri and northern Mexico.
- Cercis: refers to a weaver's shuttle (Greek kerkis), apparently alluding to shape of the fruit. canadensis: of Canada (Actually its native range probably included only the most southerly part of Ontario, however it has become naturalized in a wider region.)
- Oregon State Univ. campus: southeast of Ag. and Life Sciences, near east door. This tree was covered with "frozen fog" in December.
