Stock, also known as Matthiola, is a hardy cool-season annual native to Mediterranean and is a favourite in an Old English cottage garden and is often used as a cut flower in arrangements. The tightly clustered flowers come in shades of white, pale pink, cream, cerise pink, purple, peach, red and lilac and have a beautiful sweet and spicy fragrance from the blossoms. The most commonly planted forms are common stock (Matthiola incana), which ranges from 8 to 30 inches tall, and evening-scented stock (Matthiola longipetala bicornus), which is 12 to 14 inches tall.
Caring for Stock as a cut flower
Purchase stock when half to two-thirds of the flowers on the stalk are open. Look for straight, sturdy stems, and avoid stems on which the lower flowers are decaying.
Remove any foliage that will be below the water line of the vase or container. For longest flower life, cut the stem under water and use a floral preservative.
Change the water of your stock bouquet daily because stock is susceptible to mildew,
