Sweet Basil
Pesto Perpetuo Basil is a culinary herb that grows into a compact mound of 12 to 24 inches tall, designed for continuous harvest throughout the growing season. Unlike traditional basil varieties that bolt quickly into flower, this cultivar stays focused on leaf production when you pinch off blooms regularly, making it reliable for gardeners who want steady pesto-making material without constant replanting. Plant it in full sun with consistently moist soil, space plants 12 inches apart, and you'll have fresh basil from summer through early fall.

This basil variety thrives on regular harvesting and pinching, responding to each cut with denser growth rather than stretching toward flowers. The key to success lies in treating it as a living crop that needs active management: harvest in the morning when oils are strongest, pinch off flower buds as they appear, and keep soil consistently moist. Start harvesting once plants reach 6 to 8 inches tall, then continue through the season for the most tender leaves and best flavor.
Pesto Perpetuo Basil is grown specifically for fresh leaf harvest and is best suited to making pesto and other fresh basil preparations. The variety's focus on continuous leaf production rather than flowering makes it particularly valuable for cooks who want a reliable supply of tender basil leaves throughout the growing season, rather than one concentrated harvest.
Start seeds indoors at temperatures between 60 and 75 degrees Fahrenheit. Transplant outdoors once soil has warmed and frost danger has passed.
Transplant seedlings outdoors when soil is warm and frost risk has ended. Space plants 12 inches apart in full sun.
Begin harvesting once plants reach 6 to 8 inches tall. Harvest in the morning when the plant's essential oils are strongest. Pinch off flowers and harvest leaf tips regularly throughout the growing season to encourage new growth and maintain the plant's productivity. Continue harvesting through the season until frost or cold weather is expected, at which point harvest any remaining leaves as the plant will be killed by freezing temperatures.
Pinch off flower buds as they form to redirect energy into leaf growth rather than seed production. Harvest leaf tips regularly throughout the growing season; this pinching and harvesting actually prunes the plant into a denser, bushier form. Remove the remaining basil before frost or cold weather arrives, as the plant will not survive freezing temperatures.
