Pyrethrum ~ Chrysanthemum cinerarifolium
$5 per plant in 9cm pot
C. cinerarifolium is well tolerant of coastal conditions and grows best on stoney dry sites with plenty of sunshine – and if you have it, on a hillside. Just like its home ground. Apparently the higher the elevation that they’re growing the stronger the flowers are in pyrethene, the active constituent that affects the nervous system of insects. If you’re interested, Kenya is actually the biggest commercial producer of pyrethrum for insecticidal use.
