Jacobaea Species, Dusty Miller, Silver Ragwort

I live in Brownsville/Olmito, Texas. I bought a few of these last spring for added interest in my containers. I mixed them with dianthus,...Read More marigolds, and ageratum. Since they are listed as annuals, I never expected them to make it through to this year. They did and they are three times as big and ready to bloom! I loved them so much; I bought more this year and planted them in my garden beds between pentas and ixoras! Gorgeous addition to my flowery garden beds! Everyone who comes to my house asks what they are and where I got them.

I bought 2 (two), 4" pots at the nursery late last Spring, (2011) intending to plant them on the Eastern-facing side of my house. I sat...Read More them, in their pots, on the ground where I planned to install them, and promptly forgot about them. I ignored and neglected them all this time until yesterday when I finally brought them inside and re-potted them into larger pots... and they're still alive!!! True, the roots had grown out of the holes in the bottoms of the pots into the soil beneath them, but they're green through-and-through. Talk about tough plants!

Cuttings also seem to root quite readily.

It would seem that if it is green, I can kill it!

Well they only had to live through the weekend, so I got 5 of them, planted them in front of my porch, & literally forgot about them. I have managed to kill everything else, even my grass is brown most of the year, but I have gorgeous Dusty Millers, bigger and fuller than ever! Hey, thank goodness my kids aren't green!!

This year, I planted Dusty Miller with Lavender in a border that gets sun for most of the day. The effect is truly beautiful.

They're flowering right now. I expected them to be annuals and I watched for signs of the plants' demise, ready to pull them out, but it never came. It seems to love our NC summers and hangs on in the winter. Since the one out front started looking a little straggly with the flowers I did some trimming and placed the cut flowering stems in a vase which has been looking good (and kind of interesting as a cut stem) for two weeks. Looks great next to the purple foliage of Setcreasea and also next to the foliage and blooms of Lavender.

This plant is hardy to USDA Zone 5 without a doubt. I have had it growing in a difficult spot for 3 years. I finally took 2 root divisi...Read Moreons after 3 years of growth. It also puts down roots from branches as it grows wider. I prefer to cut it back in the spring to eliminate the 2nd year growth and do without the yellow blooms. They are pretty but the plant itself ends up looking tired and like its cousin ..... ragweed. This is a great plant to place in between greenery for a contrast in the garden. For the drier climates ... this is a hardy plant that thrives.

I planted this as an annual but learned that it works wonderfully as a perennial. Here in NJ, Zone 6b, I leave the plants in through wint...Read Moreer. After a thaw, I break out the rotted centers of the plants. In spring it sprouts again peripherally, coming back stronger and thicker than before.

I've found it easy to grow, but I just don't personally care for the appearance.

I agree with henryr10 about the climate rating for this. I'm in 7b & this comes back from year to year & often, never dies down. I grow m...Read Moreine for the foliage - a nice contrast with purples, blues, & pink coloured flowers or sun-loving coleus.

Personally, I think the yellow flowers clash with the foliage so don't allow mine to flower. I've noticed it gets very sad looking by the end of summer - I think powdery mildew gets mine as I don't have enough air circulation around them. But I trim it down & it grows back again. Not the most fantastic plant but is a good workhorse to mix among other, more spectacular flowers.

I grow them in zone 9a. They die out by the middle of the summer, but most of the annuals that I plant in the spring do the same thing. I...Read Moret must be the heat.

A beautiful contrast to other plants

Dusty millers are grown as annuals in zone 3, where they are prized for their silvery-grey foliage. The leaves are actually green, but c...Read Moreovered in tiny hairs which reflect light, giving them their silvery colour. This also minimizes moisture loss, making them drought-tolerant, and able to withstand hot temperatures. They make a good contrast for darker flowers or foliage... a common companion is pelargonium (geranium). They are also good in "moon gardens" as their foliage reflects moonlight. I've never seen them flower, probably because the growing season here is so short. They can withstand a light frost and will often outlast most other annuals into the late autumn. Even when killed by a hard frost, they largely retain their form and can be kept until spring for winter interest.

Despite a hacking, it quickly comes back to a lush, lovely bush that adds a grand colour of gray to the area, espcially wiht its yellow flowers. Planted next to daylilies and amaranth, its perfect.

It will die back to the ground, or in some cases thicker stems, and by early/mid Spring is starting new growth.

Unlike other commentators, I have had no trouble growing this plant, but then my experience is in a Mediterranean climate which is apparently ideal for this plant.

Requiring full sun, Dusty Miller does best in well-drained soil (even sandy soil with frequent irrigation). Although once established, it is fairly drought tolerant, it should be watered during prolonged dry periods (do not overhead water). Until the root systems are well established, new plantings may require daily watering, especially in sandy soils. It contracts a rust disease during prolonged hot, wet periods, declines and eventually dies which is what happened to my plants. Planted where it does not receive full sun, it beomes leggy which is not very attractive. It may be pruned to encourage bushiness.

In subtropical habitats such as the Gulf Coast and Florida, it is usually grown as a winter annual. Tolerating extreme heat, it can not withstand frequent rain. In California that does not receive a lot of summertime rain, it is grown as a perennial. It should be grown as a summer annual in colder climates. It is easily propogated by semi-hard stem tip cuttings from semi-hard stem tips in in the summer. It can also by propogated by seed, but be sure not to cover the seed with soil.

I give it a neutral rating because this plant was beautiful for a while in my garden, but did not sustain itself over a 2 year period without frequent trimming which negates the production of flowers and because of the rust problem. However, I mainly grew them for their foiage. As an annual, they would be okay. I have them listed in my database as a plant to avoid.
