I got the seeds, the cultivar "Jackpot."

The adult plant grows to 2 feet high and across, blooming from late May to mid-June. The hundreds of white flowers look like baby's breath, so they form a wonderful backdrop to the other flowers in the garden.

Jackpot loves it hot and dry, so it's well-suited for Utah.

After blooming and going to seed, it's necessary to cut off the dead flowerheads and foliage down to the basal foliage, which has woody-ish stems. The foliage stays green throughout the winter.

It self-seeds well, and the adult plants usually last only three or four seasons.

It wintered over and after the snow cleared it was there again. It is now about 4' across and about 24" tall and just covered with the white daisy blooms, just like the picture and the reason I bought the seeds. They do seed themselves and I transplant the babies but now I know that they just need to be left alone. We irrigate our Mums where this plant is growing but there is weed mat down and the seed wen... read more
