Answer: The name annual stock can be applied to a number of plants. Matthiola incana includes Ten Week Stock which is a dwarf strain about a foot and a half tall, as well as the Imperial strain which is much taller, to 30 inches. There is the evening-scented stock, Matthiola longipetala, which is also an annual. All of these make good cut flowers and grow best in cooler weather since they usually die out once the summer turns hot. The flowers come in shades of white, pink, purple, red and cream and have a delicious fragrance. In my opinion, they are not much to look at but the fragrance makes them definitely worth growing.
