1. Flowers that landscapers use for Exciting Seasonal Color, like celosia and petunias and dusty miller and most wretched of all, ornamental kale, which always makes me wish I had a 7-iron with me.
2. Eggplant. How can something that looks so pretty be so revolting? I tried here to think of a celebrity to which I could equate it, but revoltingness is so anathema to prettiness in humans.
3. Cilantro. I don’t like eating it and I’m not growing it. Ditto cumin, which I’ve always felt had kind of a dirty-gym-clothes aroma.
4. Pumpkins. What would I possibly do with more than one pumpkin a year? For that matter–what would I possibly do with ANY pumpkins, given that I’m too scared of klutzily filleting myself to carve a Jack-o’-lantern?
5. Ornamental gourds. Right up there with crocheted Thanksgiving-turkey throw pillows and dish towels depicting Santa Claus in long red underwear in terms of seasonal decorative objects having no intersection whatsoever with any stylistic theme in my house.
*J*D*L* 
…now I have this urge to scour the yardsales this summer for Santa Claus tea towels, turkey-shaped crocheted throw pillows, and decorative objects made out of ornamental gourds — perhaps a bird house?
