This is my first year garden too, and my summer squash had the same spots, but they were on the leaves. I couldn't see down to the bottom because realized too late that I'd planted too thickly. Initially, I tried cutting off each leaf that had the powdery white spots. That slowed down the speed of the spreading, but it would still spread. I was careful to wash all my garden tools as well to prevent spreading the fungus, and I also watered from a soaker hose, never on top. I thought because it had been so hot, fungus wouldn't be a problem, but it was! I was chopping off so many powdery mildew leaved, I was afraid it would inhibit production. So, off I went to the store to pick up some Daconil. So far, I've done three applications, and everything looks MUCH better. However, I still see lingering signs of powdery mildew trying to rear it's ugly head. Try treating with a fungicide. Powdery Mildew spreads SO, so quickly. Good luck to you. And, if it's not powdery mildew, then I don't know what it is.

Ok. I went looking for some of the seed mixes in "plantable" cards and here's some I found from different vendors... #1 Mountain Garland, Siberian Wallflower, Shasta Daisy, Chinese Houses, Lance-leaved Coreopsis, Purple Coneflower, Spurred Snapdragon, Forget-Me-Not, Johnny-Jump-Up, Blue Pimpernel, Chinese Forget-me-not, European Columbine, Annual Candytuft, Sweet William, Foxglove, Annual Baby's Breath, Baby Blue Eyes and Corn Poppy. #2 Red Corn Poppy, Corn Poppy, Spurred Snapdragon, Catchfly, English Daisy, Showy Evening Primrose, Gold Yarrow, Roman Chamomile, Tussock Bellflower, Foxglove, Fringed Sagewort, White Yarrow, Red Yarrow, Monkeyflower and Creeping Thyme #3 Sweet William Pinks Dianthus barbatus Rocket Larkspur Delphinium ajacis Candytuft Iberis umbellata Baby Blue Eyes Nemophila menziesii Corn Poppy Papaver rhoeas Forget-Me-Not Myosotis sylvatica Wallflower Cheiranthus allionii Columbine Aquilegia caerulea/A. vulgaris Blue Flax Linum perenne lewisii Zinnia Zinnia elegans Lemon Mint Monarda citriodora Five Spot Nemophila maculata Catchfly silene armeria English Daisy bellis Perennis Sweet Alyssum lobularia maritima Spurred Snapdragon linaria maroccana Corn Poppy papaver rhoeas Black Eyed Susan rudbeckia hirta #4 Catchfly silene armeria English Daisy bellis Perennis Sweet Alyssum loblaria maritima Spurred Snapdragon linaria maroccana Corn Poppy papaver rhoes Black Eyed Susan rudbeckia hirta And so on. Google has more but these are some of the top hits. These lists may inspire other suggestions.... While your card could be of a different mix, I suspect that your plants are pretty common garden plants - that is what most of these mixes feature. And I think it is most likely one of the plants already suggested to you. Conditions and the youngness of the plant could make the leaves not appear like mature plant leaves - which you will find mostly when you search for images of the plant. Keep watching. I'm sure it will eventually tell you what it is! FataMorgana

For early in the season, I really like arabis--grey green foliage, white flowers that last a long time. Very low-growing too. Salvia argentea has great low rosettes of fuzzy silver foliage, and then it throws up rather tall spikes of whitish flowers. I like the cerastiums too.

Well the plant sounds like Mugwort(Artemisia Vulgaris) it folwers like someitme in September and the folwers should look like culsters of cotton (but is not)(which can range from white to yellow) the plant is used in moxibustion (which you can google your self (lol)) Its considered very a very scared plant in some other parts of the world but here in the United States its considered a common garden weed anyway you can find out more about it following this link Moxibustion http://www.sarah-lac.com/blog/2009/03/01/moxibustion-moxa-artemisia-vulgaris-mugwort/ and Mugwort here: http://en.wikipedia.org/wiki/Artemisia_vulgaris No its not posionus at all and you should feel like fuzz on the underside of the leaves so no its not poisionus but the essential oil of the plant marketed under the name "Armoise" is a neurotoxin! You can smeer the walk way and around your home with them to keep out bugs actually they will die from eating it and rat or mice hate its bitter smell and taste. So overall its a good plant not a bad one like posion ivy >.
