My white aster has bloomed really well with lots of beautiful white flowers. But lately, the flower petals are having a slight red tinge on it. Is that normal?
When I bought the white aster, the tag says it blooms for only a season. A quick check on the internet reveals it's a perenial. So which is which?
Do I still need to deadhead the red tinged flowers to encourage new growth at this time of the year or is it too late now?
