Mass Horticultural Society, which has headquarters in Wellesley, is scrambling to solve its financial challenges and the Globe has the latest roundup of the blame game that’s going on. The board points to overspending under a recent executive director’s tenure, while he points out that the board approved any spending. Meanwhile, attempts have also been made to rope the Attorney General’s office into the mess. Also up in the air is the society’s annual spring flower show, which appears possibly headed for a big downsizing, though one thought is that it could take place at Elm Bank Reservation instead of in Boston next ime around. There’s also still talk of charging people to check out the flower gardens at Elm Bank, something that society officials have been considering for years (in fact, that was part of the reason it put up that black metal fence a couple of years back).
