It looks very good to me. I even see a bud forming in the crown. I would have bought it for that price. In the right conditions, they grow fast and the older, outside leaves will yellow and wilt from time to time. Carefully cut or gently pull them off as close to the crown of the plant as you can get when they start to die.

Grow this plant in a fast draining soil-free potting mix (I had great luck with 5-1-1 discussed on this forum). Fertilize with a complete fertilizer according to package directions and don't let it go completely dry. I grew mine in bright dappled sun in a hanging basket last summer. The flowers will wilt as dramatically as the leaves when they start to die. If they don't perk up on watering, remove them like the leaves. Berber daisies are prone to fungus if their crowns are planted too deeply or get too wet. The nubs from flowers and leaves you remove are most vulnerable.

I meant to say gerber daisy, not berber daisy! Was posting from my cell phone.
