3. Old wood stems are not much st... read more

The stems of the shrub are stronger than on Invincibelle. I appreciate the tie to breast cancer research for invincibelles but I feel this is a cheap ploy often to lure buyers into feeling better about their purchases when only cents go towards any benefit cause.

The stock of Bella Anna I have seen at one location had very dark blue/green leaves. The leaves alone, even if it never flowered, were enough for me to buy one. I have seen the leaf in a lighter green at another nursery. I don't know what causes this variation.

The flowers are a magenta/pink color when opening. I'd say they are brighter, mo... read more
