Geraniums are easily the easiest patio plant to grow. They also look great in flower beds and window boxes. There is absolutely no reason not overuse these beloved garden plants.
5 Reasons to Plant Geraniums
1) Did I mention that they are easy? It's hard to not be successful with geraniums. Take advantage of the fact that they like sunny areas and don't like to be overwatered.
2) They can be propagated by cutting — again very easily. All you have to do is snip and then re-plant to make new plant babies. See more detailed instructions here.
3) They come in a huge variety of scents. You may think that you don't like the smell of geraniums, but did you know that they come in rose, lemon, mint, fruit, nut, and spice scents? This article has a great list of varieties categorized by fragrance.
4) True geraniums or perennial geraniums (also called 'hardy geraniums') are very easy to grow and will come back year in and year out. These geraniums are slightly less well known that their more prolific annual cousins the pelargoniums (which is what most people think of as geraniums - geranium naming is a very confusing subject). They come in a range of colors, from soft pinks and purples to blues, magentas and whites. Read this if you are still confused about geranium naming (hardy vs. tender).
5) Both perennial geraniums and Pelargoniums (annual geraniums) are extremely pest resistant. Deer, rabbits, and other furry pests leave them alone completely. The only slight concern is for slugs, but only on plants that are in too much shade or getting too much water.
