I bought this pricey Madame Julia Correvon Clematis because the tag said it performs well in warmer areas where large flowered Clematis will not grow. I planted it with care about two months ago and it seemed happy than suddenly looked sick. the flowers are few now.

We had a week of rain and this really didn't help the vine. Any ideas on what steps I should take? The roots were kept cool by shading with another plant.
