65 DAYS With a mild, sweet, buttery flavor that's never bitter, Buttercrunch has a larger, more compact yellow-white heart than other bibb types. Dark green, reddish-tinged leaves form 4.5" rosettes of thick, blistered leaves that are bolt resistant and free from Mosaic Virus. Make planting Buttercrunch a cinch with seed tape! Seeds are encased in biodegradable paper that protects the seeds during germination and dissolves in the course of watering. Simply cut the tape to the desired length, place in the garden or in one of our Grow Tub™ containers and water—no worries about over- or under-seeding!
