Q.Pieris Katsura new growth is green
I have a healthy pieris which was sold as Pieris Katsura. It has plenty of new growth but since I have had it the new growth is mainly plain green. Only 1 or 2 of the new shoots had a hint of deep red. Can anyone tell me why this might be? Are there varieties with green new growth? Thanks!

Thanks so much for your advice. I'm sorry I should have been clearer with my question, the new growth is green right from the moment it begins to grow and never has any red colour. Does this change your answer?

Leaf colors last for 2-3 weeks and then turn green as they mature.
This shrub does best in full sun to partial shade. It requires an evenly moist well-drained soil for optimal growth, but will die in standing water. It is very fussy about its soil conditions and must have rich, acidic soils to ensure success, and is subject to chlorosis (yellowing) of the leaves in alkaline soils.
