It flowers prolifically from spring into late summer, demanding only full sun and moderate water to perform beautifully.

Albus Sweet William shines as a cut flower, with sturdy stems that hold their pristine white color in the vase for days.

Start seeds indoors 6 to 8 weeks before your last spring frost, sowing at a depth of 1/16 inch. Germinate at 65 to 70 degrees Fahrenheit; once seedlings emerge, move them to a cooler location between 55 and 65 degrees to encourage sturdy growth.
Transplant seedlings outdoors after the last frost date has passed. Harden off plants by gradually exposing them to outdoor conditions over 7 to 10 days before planting in their final location.
Sow seeds directly outdoors in spring or from spring through mid-summer. Direct-sown plants typically bloom the following year rather than in their first season.
