Centum™ White Matthiola

Centum™ White is an upright Matthiola incana from PanAmerican Seed’s Centum series, bred for uniform timing and spring greenhouse production. The grower lists 25–32-inch plants and early-spring through late-spring flowering. Selectable plants produce about 50% double-flowered types, and single-flowered seedlings can be removed while young; see the [Centum White plant profile](https://www.panamseed.com/Products/074602896005863/matthiola-centum-white/). ## Growing Grow this stock in a sunny greenhouse and follow the seasonal transplant-to-finish schedule. Centum is a spring-flowering series; planting outside the listed timing can delay flowering. Its upright stems suit cut-flower production. ## Maintenance Inspect plants while young and select out singles when double blooms are preferred. Use the appropriate seasonal production window to keep flowering uniform and on schedule.
