Easy to grow and a hardy perennial, catnip is a gentle medicinal herb for humans as well as magic for cats. Catnip thrives in gardens as well as raised beds and containers, even in partial sun, always one of the first perennials to emerge each spring. Beneficial pollinators will be thrilled you’re growing catnip, as well! Sow catnip about 4 weeks before final frost (soil blocks are our go-to) to transplant after frost with one foot between plants.
