do pomona scotch brooms come back every year and do the flowers bloom constantly threw the summer? |
Scotch broom (Cytisus scoparius) is considered winter hardy to zone 6 so it should be hardy in your area. However, it requires a well drained location or it will not overwinter successfully. Scotch broom blooms once a year for a short period in the spring. I should also mention that it tends to be short-lived, and may die back or die out unpredictably. |
