Scotch broom

Scotch broom

Help! Does anyone have any tips or tricks for growing scotch broom? I have successfully killed at least three of these plants over the years, and I am getting really frustrated! My latest attempt made it through last year OK but now it is really brittle and there are no buds on it, so I think it is mostly dead. We didn't have a really bad winter here in the Boston area last year so I am wondering if there is something I am missing. Thanks in advance for your advice.
