Blueberry Swirl Phlox is a stunning heirloom annual with blooms that blend deep blueberry-violet petals with creamy white marbling, creating an almost painted effect on every flower. Reaching just 18 inches tall with a naturally mounding habit, these low-growing plants produce flowers continuously from early summer through fall (85 days from seed to bloom). Their drought tolerance and pollinator magnetism make them as practical as they are beautiful, thriving in full sun with moderate water and adapting well to containers, borders, or cutting gardens.

The bicolor petals swirled with blueberry-violet and cream create an almost hand-painted appearance that catches every gardener's eye. The plants' compact mounding tendency means they naturally fill spaces without leggy growth, and they generate flowers from June straight through November in most climates. Cut them frequently for bouquets and the plants respond by blooming even more prolifically. They handle dry spells well once established, making them reliable performers even when watering gets forgotten.
Blueberry Swirl Phlox shines as a cut flower, with blooms lasting well in water arrangements. The low, mounding growth habit makes them exceptional in hanging baskets and container gardens, where their dense flowering can be showcased at eye level. They're equally at home edging borders or filling in gaps in ornamental beds where their long bloom season provides continuous color.
No timeline data available yet for this variety.
Sow indoors 6 to 8 weeks before your last frost date. Keep soil temperature between 55 and 65°F for germination. Cover seeds with vermiculite to maintain humidity during the 7 to 30 day germination period.
Transplant seedlings outdoors after the last frost has passed, spacing plants 10 inches apart. Harden off seedlings gradually over a week before moving them to their final location.
Direct sow in early spring once soil can be worked, and optionally make a second sowing six weeks later for extended blooms. In mild winter areas (zones 8-10), fall sowing is also viable.
Cut flowers in the early morning when they're fully open but still fresh. Harvest regularly to encourage continuous blooming throughout the season. Stems last exceptionally well in water, making frequent cutting a practical way to extend the plant's productivity.
Pinching back young plants encourages branching and enhances their natural mounding tendency. Deadheading spent flowers throughout the season keeps plants blooming prolifically. No extensive pruning is needed due to their compact, naturally tidy growth habit.
