Throughout the ages, plants have provided humans with delicious greens to eat, fresh oxygen to breathe, and a reason to attack the soil with oversized forks. Fill vigorously tilled ground with today's Groupon: for $15, you get $30 worth of plants and services at Broken Arrow Nursery in Hamden.

Broken Arrow Nursery's selection of 1,500 different trees, shrubs, and perennials herbaceously caters to inspired green thumbs. Every spring for 27 years, the nursery's 25 acres of farmland come alive with leafy plants, most of which are cultivated by Broken Arrow's staff of horticulturists. Their plant catalog is filled with vibrant shade perennials, such as wild columbine ($10 for four-pint container) and lily of the valley ($15 for four-pint container) for adorning yards or strewing over sleeping green giants. Cheery sun perennials, such as the brightly hued Fireworks goldenrod ($16 for 2 gallons), can happily share soil space with grasses, including the deceptively quiet Heavy Metal switchgrass ($18 for 2 gallons) and sugar-free Peppermint Stick giant-reed grass ($25 for 3 gallons). A wide variety of trees and shrubs is also available. For those needing additional aid in garden beautification, Broken Arrow offers services that include landscaping, delivery, and more.
