bracingwind - do you have access to both these plants?If so I suggest you take one to the other and compare them. Here's a couple of things to start you off (not using botanical language): PHLOX PETUNIA 1 - 4 feet high about a foot upright and stiff sprawling and floppy leaves smooth leaves hairy and sticky slight phlox scent strong petunia perfume esp at night furled buds ridged buds flowers in a bunch flowers separate or in smaller clusters You need to look at all aspects of a plant, not just superficial appearance of the flowers. As you learn you will soon realise that there is no way you could mistake one for the other.

Looks like a Ruellia.

I grow two Rose de Rescht bushes here in hot, humid Alabama. I planted them last February in all day sun. The bushes are nice rounded mounds that are about 3 ft x 3 ft now. The bushes are attractive and have stayed pretty clean without spraying. The blooms are beautiful and smell like heaven. Each had a big first flush...completely covered in blooms and have had good rebloom since. They haven't been covered in blooms again, but have consistently had several blooms each. The blooms don't last long on the bush and only a day as a cut flower, but the petals fall off and self clean without drying up and turning ugly. Color is pretty true to the first pics below that were taken in very hot September...not as purple as they look in the last couple pics which were taken in spring on a different camera.

Busyasabee gave me a rooted cutting of this rose at the last Mid-Atlantic plant swap. It's got a couple of buds, so I'll try to take a close-up photo of the flowers when they bloom. Meanwhile, I've posted a photo that B. sent me of the bush on the Rose Gallery - it's probably the same one that she tried to link to. As you can see, it's a really pretty shrub!
