Column Stock Purple Heart Matthiola

Column Stock Purple Heart is an upright field-grown stock raised for florist stems, with mature plants listed at 24–30 inches. PanAmerican Seed gives a 20–22 week direct-sow-to-finish schedule and lists flowering from late spring through summer and late summer. The single-stemmed florist type forms close-set, scented flower spikes; this variety is identified as Purple Heart.

Cool growing conditions help produce longer stems, while high heat can stunt growth or prevent flower spikes from developing. The supplier lists this crop for field production and provides a planting-density guide of 2.2 pounds per acre. ## Maintenance Keep the crop evenly established while it develops, and monitor temperatures during stem growth. Use the supplier’s crop schedule for sowing and finishing, since flowering dates depend on when the crop is started. This variety is non-selectable for doubleness, so plan production without relying on seedling selection to separate flower forms.
