Flowers

For all the avid gardeners out there and those aspiring to the club, yet another way to save money!
Rather than spending hundreds of dollars at the local nursery, ask your neighbors and friends for cuts or shoots from existing mature plants that they have. Most perrennials need to be thinned every couple years anyway, so put the word out that you're interested and then when people are tending to their flowers, your name will come to mind!
Study up on how to grow great flowers from shoots, bulbs, seeds and cuttings. There are lots of guides available at your local library and online. Also take advantage of wise green thumbed friends and family. 
With a little effort, flexibility and planning, you'll have a magnificent yard for lots less than your neighbors paid!
