Waltham 29 Broccoli was developed by the University of Massachusetts (and named after Waltham, MA) to withstand the colder weather of the Pacific NW and the East Coast. Plants germinated indoors should be transplanted as soon as possible after your average last frost date. Alternatively, plants may be grown for a fall crop, transplanting seedlings into the ground about 12 weeks before your average first fall frost date. Waltham 29 broccoli is quite prolific, producing many side florets after the main stalk is harvested.
