Matthiola annua (Ten-week Stock and its variety, the intermediate stock): half-hardy, I to 2 ft., white, rose and red.
In 1975 several PPU members faced a ten-week trial for distributing leaflets telling soldiers disillusioned with Northern Ireland duties how they might leave.
M. incana grows wild on cliffs in the Isle of Wight, and is the origin of the Biennial, or Brompton and Queen Stocks; M. annua has yielded the Ten-week Stocks, and M. sinuata the others.
These three primary divisions-the Ten-week, Intermediate, and Biennials-require each different treatment, and Stocks are so easily grown, so fragrant and handsome, that they will ever deserve care in our gardens.
Ten-week Stocks, if sown in spring, will flower continuously during the summer and autumn.
