About Cole Gardens, Best of New Hampshire writes,

New Garden Center: Cole Gardens at the far end of Loudon Road in Concord (229-0655) has been making its mark as the best new purveyor of plants, starts, garden supplies and good advice (they specialize in organic starts for the serious organic gardener). Everything is beautiful and it’s a great (and vast) place to wander, just to get in the mood. Speaking of moods, they are open year-round and they welcome anyone with seasonal affective disorder into their giant greenhouse during the dreary months of winter.
