Product Description
The flowers, typically white with a yellow center, grow from numerous, fairly rigid stems, producing an umbrella-shaped or even canopy. Plants have blue-green leaves and grow to between 24-30". The centers of the flowers contain more pyrethrins than the outer petals. Harvest at full development 5-9 days following the first flower. Considered to be among the safest insecticides for use around food. Pyrethrum is economically important as a natural source of insecticide. The flowers are pulverized and the active components called pyrethrins, contained in the seed cases, are extracted. Pyrethrins attack the nervous systems of all insects, and inhibit female mosquitoes from biting. When not present in amounts fatal to insects, they still appear to have an insect repellent effect. They are harmful to fish, but are far less toxic to mammals and birds than many synthetic insecticides and are non-persistent, being biodegradable and also breaking down easily on exposure to light. This is not an easy plant to grow, but once started it will re-seed itself each year.

I have grown Pyrethrum chrysanthemum before. Wonderful plant once established in zone 9. I found these seeds slow to germinate but once they did, the rate is about 50%....so far I'm satisfied. This was the best price for the number of seeds in package so the germination rate is not an issue. If the package contained 50 or so seeds then it would be.Most of the consumer Reviews tell that the "Herb Pyrethrum, Tanacetum cinerariifolium 100 Open Pollinated Seeds by David's Garden Seeds" are high quality item.
