Matthiola incana Mathilda™ White
Stock · Group 2
Mathilda™ White is a premium greenhouse-bred stock variety producing elegant, pure white, highly fragrant blooms on strong, uniform stems. This Group 2 variety is bred for uniform stem length, synchronized flowering, and improved heat tolerance, making it ideal for professional cut-flower production.
Plants are cold-tolerant down to 22°F / –6°C and can be grown earlier and later in the season than traditional field types. In suitable climates, the Mathilda™ series allows for programmable, near year-round production, including winter flowering for Christmas through Valentine’s Day harvests.
Approximately 50% of plants will produce double flowers, with doubles easily selectable at the young plant stage.
