How to grow Stock

Stock (Matthiola incana)

Stocks are famous for their fluffy, fragrant blooms that are abundant and aromatic.These cherished plants flourish in cooler temperatures. A mere handful of stems from these beauties is enough to make a significant impression in both gardens and bouquets, infusing the surroundings with their delightful fragrance. Half of the plants will be single-flowered, the other half double, so plant twice as many as you need.
