(Lettuce) Nothing is more satisfying than the homegrown goodness of garden fresh lettuce. The ‘Heatwave’ Blend is a mixed selection of fresh green, purple-red, crispy types; deep to bright green romaines; oak-leaved; crisped-frilled; broad, soft looseleaf; and savory, bronze-purple, fern-leafed lettuces. Ths ‘Heatwave’ Blend grows to 12 inches tall and 12 inches wide. The varieties within this blend are slow to bolt giving you quality lettuce to harvest longer in the season. Trim often and watch the new growth emerge. Plant in full sun to part shade locations and water often for best results.
