Stock is a biennial or tender perennial that is winter hardy to USDA Zones 7-10. In St. Louis, it is grown as a cool weather annual in average to humusy, consistently moist, well-drained soils in full sun. Plants tolerate some light shade.
What is Hardy Biennial? Upright bushy, early flowering biennials producing gloriously scented flowers in a good colour range. Brompton Stocks make a wonderful, fragrant addition to borders and containers and are splendid for cutting too.
Cut off the entire flower spike to the next lateral bud with a clean pair of garden scissors when all of its flowers have faded. The next lateral bud is usually at the joint between the first set of leaves under the flower spike and the stem. The stock plant should send up an additional flush of bloom.
Harvest when one-third to one-half of the blossoms on a stem are open and remove most of the foliage. Stock is an extremely long lasting cut and will last up to 10 days when water is changed frequently.. . . . .364011234388!]0000000000000009783314146749!]
