Botanical Interests Waltham 29 Broccoli Seeds
Broccoli has a long culinary history going back to the Romans. The florets, leaves, and stems are packed with vitamin C and provide calcium, potassium, and iron. The 4"-6", blue-green heads are delicious raw or cooked. 'Waltham 29' grows prolific side shoots and is specially adapted for cold tolerance. Freezes well. Kids will delight in the "little trees" on their plate.

"BEAUTIFUL! Happy, helpful people and GREAT selection of decor (live and artificial), gifts, and unique items."

"As a new empty-nester I've gone down the houseplant rabbit hole and have seen most of the small nurseries in Denver metro. I will drive to go to this AMAZING Garden Center for the variety and quality of their fabulous stock. Better than Paulinos was and that is SAYING something. Staff is beyond helpful and amazing, free repotting if you buy pots too. Really unique home and gift retail. You won't be sorry! Everytime I go up to see my kid at school, I make a stop to see what new inventory they've gotten in... 13/10 highly recommend."
