Unfortunately I learned that bigger is not always better - I was overwhelmed by their selection and didn't get much help from the staff (I think they would be more helpful if I had a specific question rather than "I need some pretty flowers"). I ended up buying some impatiens, which my Studly Hubby potted in a big pot to put in the backyard, and then I bought three things for the very sunny south-facing front yard:
Trailing Verbena hybrid (in Aztec pink)
and two kinds of Sedum: Sedum spathulifolium, which I'm pretty sure I had in my old lab (the one Uncle KT smashed all over the floor in a frothing mad rage one day), and Sedum ogori. I took pictures, but it was just before sunset (at 9:30 pm, sunset is getting earlier...!) so everything is getting dark.
The staff "helped" me by trying to get me to buy a $50 hardcover gardening book which they said didn't even have good pictures. Despite this hurdle, I managed to get some good stuff. Instead of buying the book I carried it around with me at the store and looked up everything that looked pretty until I found a few that were just right - hardy, likes sun, blooms all summer. Yay! I also bought a trowel and some gloves, and when I got home I planted them and watered them and three days later they are still alive. Yay!
At my book club tonight I was informed that it is not too late to plant veggies in Seattle, so that is my next plan. I'm going to buy some interesting seeds, clear out more of the garden, and throw the seeds in a hole and see what happens. My Studly Hubby also nabbed a free package of wildflowers from work and it is a mystery what that will grow so I'm going to put that somewhere too. This gardening thing is pretty fun, especially when things bloom and grow.
