Massachusetts Horticultural Society (Wellesley, Mass.) 2015 Field Trials Results

The New England Trial Garden displayed a total of 230 entries this year: 160 annuals and 70 perennials. The annuals are tried in the ground and in 12-inch patio pots. The perennials stay in the ground for two years to monitor their hardiness in the New England climate. New this year was the trial promoting 50 heirloom varieties of tomato, squash and peppers, including local varieties from New England.

After a record-breaking snowy winter and a last frost in April, the trials had up and down temperatures in May and weekly rains until June. The three months of summer were very dry, with two heat waves and about 10 days over 90°F, even in September. Rain had just returned in the end of September.
