One of my favorite catalogs is White Flower Farm. Here is a photo from their web site.....
Another great source is Baker Creek Heirloom Seeds. I want to try more heirloom plants in my garden this year. One of their retail stores is located in Mansfield, Missouri, and I plan to visit this spring.
I also believe in growing native plants, and native wildflowers are great if you are concerned about conserving water. In Missouri, we have a wonderful nursery near Jefferson City, the Missouri Wildflower Nursery. The photos below are from their catalog. I suggest that you google "native plants" for your state.
I love to photograph flowers and often I will digitally work with them, using them in a collage or card. Here are some of my favorites..
If you are interested in learning to digitally enhance your photos, contact me if you live nearby, but another way is to learn online and I have discovered one place that you can do just that! Go to Digital Montage Studio and take one of her classes. You will need Photoshop CS3-5 or Photoshop Elements 6-9. I am using Photoshop Elements 6 and there is a lot that you can do with it, especially if you are just starting out. You can get the latest, Elements 9, at amazon.com for under $100! You will have so much fun and you will be amazed at all of the great things you can create. Check it out!
