Flowers, Trees, and Build Limit Updates

I want more flowers and trees, specifically Pines, Dogwoods, Aspens, Crape Myrtles, and Olive Trees. Flowers? I want specifically, variants of Spireas and Daisies, also Lupines, Lantanas, Zinnias, and Hibiscus. Also, if you can, please consider adding new variants of Grass Blocks. Like dark grass, dry grass, etc. Also please make the XBOX build limit endless, or to 2,800. (I am an XBOX player and I find the current build limit still far too low)
