Huckleberry together with dangleberry ( G. frondosa , upper left). From time to time we see the two Gaylussacia species growing together, even though generally their ecology is not the same: dangleberry tends to prefer rather damp and mild, more or less mesophilous forest sites, while huckleberry can climb rocks and cope with other such harsh and nutritionally poor environments (for example, it thrives in pitch-pine barrens).
