Plants, mankind’s greatest enemy, are finally on the ropes thanks to global warming. Teach your children how to hunt the last of these enormous nitrogen junkies by observing them in captivity with today’s Groupon to Maas Nursery in Seabrook. Choose between the following options:

• For $10, you get $20 worth of plants and gardening supplies.
• For $50, you get $100 worth of plants and gardening supplies.<p>

For more than 60 years, Maas Nursery’s green-thumbed staff has been tending to the blooming foliage, gardening supplies, and décor at the 8-acre facility. The 4-inch vegetable plants ($1.50 each) and 4-inch herbs ($2.49 each) garnish entrees, season sauces, and spice up expired milk with garden-fresh zest, and colorful 4-inch perennial bedding plants ($1.99 each to $35 for a 20 flat) and bonanza camellia shrubs ($62.99/5-gallon size) add zing to monochromatic lawns.

A selection of artisanal Talavera pottery includes the Talavera bird bath ($124.99), which draws flocks of avian migrators or thirsty neighbors. Summer red-maple trees ($45.99/5-gallon size) guard grounds with a leafy fence, and organic fertilizers ($42.99/40 lb. bag) and planters round out the arsenal of tools for a healthy garden. Although not included in the price of this Groupon, landscaping services and gardening classes are also available.
