Why do my hydrangea leaves look purple and green?

They have been hybridized to do so. Selective Breeding. We do this also with succulents. Fl to F3 We plant 50 -100 seeds, and then select plants from the propagation which has the features that we want. We then collect seed from the first batch and breed them again to get F2 and we may continue to this for several seasons to achieve what we were looking for and only keep three plants from the batch that have different features, that are different. Darker flowers, deeper indents in the leaves, larger teeth for the aloe, with better color, shorter flower stems, and more flowers on the inflorescence, wider leaves, or shorter or miniature plants. This will form a new gene pool you must have diversity in the pool. Once you get what you want, then you can start from cuttings or offsets which ever applies. Hoyakins

Why do my hydrangea leaves look purple and green?
If they normally have green leaves they sound like they have gotten a bit chilled. This makes them 'autumn toned'. I always leave my leaves on my hydrangeas and don't prune to get the autumn colours. If it is spring where you are the weather may have been unseasonally chilly and it has upset them. There are also some varieties that are bred to go nice colours in autumn, particularly the species hydrangeas.
Reply:It's because hydrangeas are very sensitive to acid levels in your soil. Different acidity levels result in different colored petals. For instance, the same periwinkle-blue hydrangea plant that my aunt grew in Kentucky, grew green and pink in Texas.





There's nothing wrong with your plant; it's simply an acidity indicator.
