Column Stock Pink Sweetheart Matthiola

Column Stock Pink Sweetheart is an upright stock selection grown for field-grown, single-stem florist production. Its fragrant spikes carry closely spaced flowers; the supplier notes that doubleness is not selectable, so seed-grown plants may include single forms. The profile lists late spring, summer, and late-summer bloom, a 24–30-inch height, and better stem length in cool periods; heat can stunt growth or prevent flower spikes. [PanAmerican Seed’s plant profile](https://www.panamseed.com/Products/074600341004183/matthiola-column-stock-pink-sweetheart/) gives the selection’s growing details. ## Maintenance Grow it in full sun and keep soil consistently moist but well drained, especially while plants establish. Stock is a cool-season crop, and hot weather shortens its flowering window. Cut flowering spikes for arrangements and remove spent stems to tidy the bed.
