Answer: From your description it sounds like you have a landscape plan and will be installing it. Your trees are spring bloomers so you may want to look at summer and fall blooming perennials for seasonal interest. Annuals will bloom all summer and can also simply be chosen according to personal taste. In both cases however you will need to spend careful attention to soil preparation in order for the flowers to grow well for you. Since you are a beginner and have lots of new plantings on the way I would suggest you add flowers in a limited area at first because they are relatively high maintenance plants compared to trees and shrubs. You might want to look at a few basic books about gardening to get a rough idea of what is required in terms of initial care of new trees and shrubs, a lawn, and how to prepare the soil, slect, plant and maintain flowers. Here are several I would recommend either from the library or the bookshop: "Gardening for Dummies" (this one covers all of the above plus a bit on vegetables), "Annuals for Dummies" and "Perennials for Dummies." All three of these are straightforward and give you the information you need to get the best results from your efforts. Enjoy your new plantings!
