Lemon Balm is a Melissa officinalis perennial for Zones 4-9 with tangy, lemon-flavored leaves.
Sow on the surface because seed needs light, keep soil at 65-75ºF, and expect sprouts in 7-21 days. Start indoors 6-8 weeks before last frost or direct sow 2 weeks before last frost, spacing 12-18 inches apart. Leaves are ready around 65-70 days, picked before bloom.
