Trees are generally long-term investments, requiring considerable forethought as they’ll be around for many years, creating their own ecosystem, adding shade, creating a windbreak, or simply adding beauty and stature.

Purple was a costly hue in antiquity, with a pound of Tyrian purple dye said to cost anything up to $7,000 in today’s value. Purple flowering trees can be an exquisite addition to any garden, evoking a sense of tranquility and beauty in addition to their practical use.

Because every desire has a fulfillment burden, especially for long-term decisions, making an informed decision is prudent.

To help you make a choice that suits your needs, I’m sharing 15 different purple flower trees, with the pros and cons of each one.

I hope that helps you choose well. Please note they’re listed alphabetically – not by my preference,
