Problems with aster

First, forgive me--I don't know the species of the aster that I have. I know that it's supposed to be a bluish color, but it's more of a light purple (soil conditions, I presume). Also, I am not home to take a picture.
I've had this plant for roughly 4 years. It is planted on the south side of the house, full sun and hot conditions trending towards dry moisture levels.
It does grow, but it just doesn't do well. In fact, it looks kind of anemic. The stems and foliage are not terribly robust, though it does reach about 2' in height. The flowers are kind of sparse as well. It has never looked great, to be honest.

I noticed last night that the leaves have gigantic pale yellow spots all over them, so I am assuming it has some kind of disease.

Does this sound familiar to anyone? I have no idea if I should attempt to treat the plant, or if should just yank it.

Suggestions? Thank you!

RE: Problems with aster

Just a couple of thoughts off the top of my head:

If it's a species aster, the blooming may seem rather sparse in comparison to most of the hybrids on the market. You should try to find out what you have.

How far from the house is it planted? Reflected heat from the house itself could be frying the plant. I had problems with an aster not blooming the way it should and then realized it was planted too close to the sidewalk. Heat bouncing off the sidewalk was cooking the poor thing. I've also moved all my asters to a SE location because the SW location was just too hot in the afternoon. They're doing much better.

My asters like regular moisture. Drying out too much can cause fungal problems with the lower leaves.

Does it need division? Asters are generally robust growers benefiting from frequent division.

aachenelf, it is right next to the house. It's actually surrounded by concrete. The foundatino is behind it, and immediately to the left is the concrete driveway. 2 feet in front of it is sidewalk.

Thank you! I may try moving it and see if that helps. It's not huge enough to divide yet.
