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.
