Katz Ruby Matthiola

Katz Ruby is a named Matthiola incana stock selection with an upright habit and a listed height of 32 inches. PanAmerican Seed describes the Katz line as suitable for high-tunnel or field production, with spring and autumn flowering. ## Flowering and form The exact developer page reports that Katz selections produce about half double-flowered stems, with shorter crop time and more uniform stem length and timing than traditional field types. Some climates allow production over a longer period, but this describes grower scheduling rather than guaranteed outdoor bloom. The page identifies Ruby as the selection name and provides a 32-inch height and sun exposure. ## Garden growing Matthiola incana is a cool-season plant. North Carolina State Extension recommends full sun and average to humusy, consistently moist, well-drained soil; the species tends to decline when temperatures rise above 80°F. The Katz line is described as more heat-tolerant than European or traditional field types, but local warmth still affects garden performance.

In hot climates, schedule planting for cooler conditions and expect this cool-season display to fade as heat arrives.
