That is Cercis canadensis, commonly called Redbud.

If you want to pamper your tree, mulch it (if it's not already mulched) or extend the mulched area out a little (if it's in a smaller mulched area). Mulch -improves soil fertility and texture as it breaks down, -prevents germination of many weed seeds, -reduces competition for food and water from grass and weeds, -reduces erosion, -helps to maintain soil moisture during dry periods, -often aids drainage by preventing surface crusting and sealing, -can keep roots cooler during hot summer weather, -can help to moderate soil temperature fluctuations, -reduces frost-heaving, -reduces certain soil-borne diseases by preventing soil and fungi from splashing onto foliage, -prevents damage from mowers and trimmers, -and improves the look of the landscape.
