Gardening.

Well, my garden is well under way. I did find my Marguerite Daisies, but it turns out the particular variety I was searching for is only nicknamed a daisy, and is actually a Argyranthemum. In any case, I was estatic to find it. Lately, I'm not so estatic about it. It's a six inch high brown bushy lump. I've followed all the care instructions, and yet it's dying. Does anyone out there know much about Argyranthemum frutescens? Please let me know if you've got any advice. Thanks!
