Climbing aster is growing

The Carolina climbing aster Aster carolinianus is growing very well.
We planted it, as a seedling, this year in March (see image below), and it is now thriving.
I was concerned at first that maybe it wasn't getting enough sun.
We make sure that it doesn't dry it and give it some grape seed compost once a month.
It will be so exciting to see it bloom this autumn with lovely purple asters which will attract butterflies and bees.

This was what the aster looked like this year in March when it was first transplanted from a little pot.
