Purple Basil
Purple Ruffles Basil is a stunning ornamental herb that earned an All-America Selections award for good reason. Its deep violet leaves grow to 3 inches across with distinctive jagged, ruffled edges that make it as beautiful on the plate as in the garden. Introduced in 1984, this sweet cultivar carries spicy undertones with hints of toasty warmth. Ready to harvest in 70 to 79 days, it thrives in full sun across hardiness zones 4 through 11, rewarding gardeners with abundant foliage and vibrant antioxidant-rich leaves.

Highlights
Those deep-violet, ruffled leaves are the real showstopper here, and they're not just for looks. The flavor strikes an unusual balance: sweet basil character undercut by spice and a subtle toasted quality that feels more complex than typical green basil varieties. An AAS award winner from 1984, Purple Ruffles has proven itself in home gardens for decades. The larger 3-inch leaves mean fewer plants needed for a good harvest, and their rich purple color deepens as the plant matures in full sun.
Common Uses
Purple Ruffles works as both a culinary herb and a striking ornamental. The large leaves are excellent for fresh basil preparations where visual appeal matters as much as flavor, such as in salads, garnishes, or as a vibrant addition to cocktails and cold beverages. The leaves can be used in traditional basil applications, though the spicy, toasty character makes them particularly suited to dishes where a more complex basil note enhances rather than simplifies the flavor profile.

Care Instructions
Start Indoors
Start seeds indoors 6 to 8 weeks before your last frost date. Maintain soil temperature at 70 to 85 degrees Fahrenheit for reliable germination. Keep soil consistently moist but not waterlogged until seedlings emerge. Transplant to larger containers once they develop true leaves.
Transplant Outdoors
Harden off seedlings by gradually introducing them to outdoor conditions over 7 to 10 days. Transplant outdoors after all danger of frost has passed and soil has warmed, typically when nighttime temperatures stay above 50 degrees Fahrenheit. Space plants 12 to 18 inches apart to allow room for the large foliage to develop fully.
Direct Sow
Direct sow seeds outdoors after the last frost date when soil temperature reaches at least 70 degrees Fahrenheit. Scatter seeds lightly on moist soil; they need light to germinate, so do not cover them deeply.
Harvesting
Begin harvesting when plants reach 6 to 8 inches tall, typically 70 to 79 days from sowing. Pinch or cut the top inch or two of stems regularly to encourage branching and continued production. Harvest in the morning after any dew has dried but before the heat of the day, when leaf flavor is most concentrated. The leaves can be used fresh immediately or stored for later use. Harvest flowers if they appear to redirect energy back into leaf development.
Pruning
Pinch out the growing tip and top two leaf sets regularly from the time the plant has 6 to 8 true leaves. This encourages branching and a bushier shape, multiplying your harvest. Remove any flower buds as they appear to keep energy directed into leaf production rather than flowering. Regular pinching and harvesting will keep the plant compact and productive throughout the season.
