Chocolate Mimosa tree
I purchased a Chocolate Mimosa tree last year and the leaves were not all dark brownish purple. Some of the small leaflets (little part of the leaves) were green. Is there something I can do to make next year's leaves all the dark brownish purple colored?

Some plants need a few years to reach their full coloration. As this is a relatively new variety, there is little information on it. I would give it a year or two to reach its full potential.
