Jacobaea, Dusty Miller, Silver Ragwort 'Silver Dust'

Not only did these plants survive last summer's drought and extreme heat, but they wintered over and are currently in bloom. The plants ...Read Moreare also spreading which is fine with me. I'm quite pleased with the contrasting foliage. The lovely yellow flowers heads are a bonus.

Remarkably this plant has come thru the winter for the past 3 years in my NJ garden! It usually planted as an annual here but the mild w...Read Moreinters of the past few years have allowed the plant to come back. They look amazing planted with Russian Sage and Purple Liatris.

I have responded neutral b/c I bought this for a border plant thinking it would be 6-12". But is 3 1/2 feet tall. Beautiful plant I love ...Read Morethe grey foilage and yellow flowers. But....I used around the pond. They grew so much taller than I expected that I will need to move them or cut them way back so they don't block the view of the waterfall and pond. The flowers are very messy around a pond if allowed to go to seed. And here in southern California they reseed themselves profusely. Unless I have some variation of this plant.

A striking visual impact when grown as a single plant amidst other colorful flowers.
Seems to be fairly slow growing, and hasn't become woody.

While it did not flower last year, it is in full bloom now. It is also much larger and denser, and we only lightly mulched it prior to winter. Current foliage height is about 24"; the blooming stalks are about 36" tall.

Our experience is that this cultivar will remain perennial for a handful of years. Younger leaves have a bluish cast that turn almost pure white as they mature, and I prefer it over many of the other "Dusty Miller" cultivars for that reason.

This plant has lacy foliage, more delicate-looking than Dusty Miller. Although 'Silver Dust' can be perennial in Z8 or higher, it's ofte...Read Moren grown as an annual elsewhere. Leaves are almost white, and pinnatifid. Good for a massed foliage effect in summer bedding; matches well with bright, rich colours.

Note for Z8 or higher: 'Silver Dust' plants kept into the 2nd year may produce coarse, daisy-like flowerheads in mid-summer. Can be deadheaded, or left on.
