GoldDust® Mecardonia hybrid 'USMECA8205' USPP 22,871, Can PBRAF
  • This is an outstanding plant. I bought two last spring to fill a couple of leftover pots on my deck. They quickly spread to about two feet across and spilled over the sides of the pot, with a height of about five inches. They bloomed like mad all summer and fall. We watered regularly and fertilized once, and now in early October on Canada's west coast they are still covered in blooms. I will definitely buy several more of these next year and use them on our deck and in flower beds too. I wish they were perennial, but maybe will our mild winter they will make it through.

  • First time buyer in 2016. This is one of the most pleasant surprises. The flowers, while a bit delicate, are a vibrant yellow and it has literally hundreds of flowers blooming as I write this. Given its really low profile it must be used at edge of planter. It spills well and mine is even "climbing" a bit on the Beth's Blue and Tequila Sunrise with which it is grouped.

    Given the spreading habit of this plant I could see it being an excellent candidate for ground cover provided it does well in native soil.

    All I have to do with gold dust is water regularly and fertilize weekly. Needs no special treatment and nary an aphid, Jap Beetle or any pest on it.

    I liked the first one so much I bought another last week.

    One thing I should mention: the garden center from which I bought these takes impeccable care of their plants. Thus my Proven Winners got off to a great start. Some places like Lowe's or Home Depot kind of take the "winner" out of even Proven Winners.

  • This plant was new to me this spring (2015) but the fact that it doesn't grow tall made it a perfect choice as a front border plant. Three 2" pots spread quickly and have bloomed continously all summer. Another plus to this plant is that there is no need to deadhead. I loved how it has performed and plan to use it for both a front border plant and in my fairy garden next year. It truly is a Proven Winner!!! Please, continue to offer it.

  • This plant is definitely an outstanding plant. I have purchased it for the last four years and it has "proven" to be a constant hit for guests, family members and of course, myself. It is resilient, a stunning color and was so eager to pick them up early, but was profoundly disappointed when traveling this spring to just about every nursery on the south shore to find it, with NO results. My favorite nursery said it wasn't available this year and I raced to many to get the same answer. Please bring it back!! A gorgeous annual and lasts all summer long and into early fall!

  • Care instructions recommend sun but it it flowering beautifully in partial shade here in St. Petersburg. My plants in late afternoon sun are thirsty and not blooming nearly as nicely. It's a non stop bloomer and a great container spiller.

    Above Average Superior performance, among my favorites, would recommend to others.

  • Plant bloomed fantastically from end of May until then the end of June. No more blossoms. Waited until July 8, and, then, cut back to see what happened but it definitely went to seed.

    Unsatisfied Did not survive, inferior performance or did not bloom well - won't grow again.

  • New to me this year but planted in containers it's quickly become a firm favourite. I'll be planting Gold Dust as a container "spiller"" every spring.

  • I planted this last spring (2013) and it lived and bloomed all winter. This spring it is spreading and looking even more beautiful. It seems to be perennial in Florida.
