Tansy Seeds

Tansy is a perennial member of the aster family, with serrated, fernlike leaves and flat bright yellow flowers that resemble buttons. Originally native to Europe and Asia, tansy is now widely grown and has a number of traditional medicinal uses, though most modern herbalists warn against its use by laymen.
Modern herbalists warn against its medicinal use because all species of tansy are toxic and can cause hallucinations, spasms, convulsions, and even death in large doses.
Today, the primary use of Tansy is as an insect repellent and companion plant.

JB095 Jackpot Tansy ( Tanacetum niveum )

Sensational variety from England. Soft downy woolly grey leaves are soon overwhelmed by a shroud of white flowers, so much so that you almost cannot see the leaves. Has the same insect-repelling properties as other tansies. Not invasive.
Bright white, 1/4 to 1/2 inch wide, daisy-like flowers with a yellow center are produced in profusion from early through midsummer. Jackpot is extremely floriferous, up to 1000 blooms are produced at a time! If cut back after flowering, it may rebloom in the fall.
The aromatic, silvery-green, ferny foliage forms a nice mound similar to a chrysanthemum. The first year, it will grow to an approximate height of 18 inches. The second year, this vigorous grower may double in size.
Jackpot combines well with just about everything else in the garden. It is wonderful in mixed container plantings and can also be used as a cut flower.
A hardy perennial for zones 5-9.
