Titan™ Pure White Vinca

Titan™ Pure White is a white-flowered selection in PanAmerican Seed’s Titan F1 vinca series. The breeder identifies the selection as PAS420775 and describes a mounded, upright habit, flowering from late spring through late summer, full-sun exposure, and a mature size of 14–16 inches high by 10–12 inches wide. ## Flowering and habit PanAmerican describes Titan as a well-branched series with large flowers and a flowering window that can begin earlier than open-pollinated vincas. The [Pure White product profile](https://www.panamseed.com/products/063703034005946/vinca-titan-pure-white/) confirms the cultivar code and the series’ habit and season. ## Siting and size Use this compact annual in sunny containers or landscape plantings. Its 14–16 inch height and 10–12 inch spread fit small pots, front-of-border color, and mixed annual displays; the breeder’s measurements match the catalog labels. ## Maintenance Give the plant strong light and avoid overwatering. Kew’s [Madagascar periwinkle profile](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:77880-1/general-information) notes that Catharanthus roseus is sensitive to excess water. The breeder describes Titan as heat tolerant, but gives no cultivar-specific pruning schedule.
