All of them!!! But especially Orchids, Orchids, Orchids, Orchids and Orchids (I am something of a monomaniac).

Now I will add something that is actually relevant to this thread. Here is one of my favorite hybrid tea roses. This one is called Midas Touch. It holds its color well even in the heat, and it always has lots of flowers. They last a long time too, and are great for cutting, although it tends to produce multiple buds at the end of each stem, so if you want a tall stem with a single bloom, you have to pinch back some of the buds while they're still small so that there's only one left on the stem. It is definitely my favorite yellow. The spring blooms are definitely the best, but it blooms again in late summer too. I've even had blooms on that rose as late as December. The other flower is what I call an African Daisy. I don't know what other names it may go by. It comes in a variety of colors, but this one and the steel blue one are my two favorites.

Edit:I found a picture of the steel blue African daisies I love so much, and i finally occurred to me what else we used to call them, which is Osteospermum. I haven't tried them here in Texas yet. In Oklahoma, they tended to languish a little in the hottest pert of the summer, but in the fall when the weather would start to cool off, they would just go crazy. It gets much hotter in Texas, so it's possible the heat in August may kill them, but maybe it won't, and maybe I'll get lots of blooms in the fall. I think I'll give them a shot in my garden this year and see what happens.

DC, your purple friend: That's an annual here. I used to sell it also, as a filler it spiller for containers. It's in the Tradescantia family, I believe.

Lovely rises, JScott. They don't do well in our sand.

My grandma always grew that purple plant as a houseplant. Called it Moses in the Boat. And another purple stripey plant she called Wandering Jew. Grew up before I realized there were other names for them. She was a staunch Baptist, so perhaps thus the names?

Must go find last year's picture of my favorite rose. It hasn't done well last two winters, and is looking pretty raggedy this year. It's beautiful, in my opinion, but doesn't care for my climate.

Inn my garden shop in Oklahoma, we sold that purple heart like crazy. Couldn't keep it in stock. It's great for mixed planters because it spills down over the side, and it's a good ground cover. It is technically not supposed to be perennial in Oklahoma (zone 7), but I had a lot of people who came in and said that theirs came back every year, and could be a little invasive, so it's definitely a tough plant.

I adore lilies in the garden. I have a bit of an issue with lily beetle which requires constant vigilance in spring and early summer. But, I'm rewarded for it later in the year. They are just coming up now :D

Are those ornipets? I have mostly those. No Lily beetles (yet) but I do have trouble with stalk borers. I used to use systemic Rose food for them which work quite well, then I had to stop using it because it was bad for the pollinators. Now I try to cut them out and squash them.

Yes they are Orienpets here they get called tree lilies as they grow to about 9 feet supposedly. I've had about 7 feet of growth - they do smell amazing. Thankfully stem borers aren't present here.

Planted three today, "Big Brother."

That is the most scented plant in my garden - you can smell it from tens of yards away. It has massive blooms too - I find it needs stacked, but that's because it is wet and windy here even in summer.
