If you are looking for some plants to complement your red-flowering trees, Geraniums are an excellent choice that you can grow both indoors and outdoors with very little work. You can get them just about anywhere and if you feel like a little contrast to compliment your tree then Geraniums have got you covered there too – as a genus of over 422 species, you’ll find white, pink, purple, orange, reddish-black, mauve, and more. Give them a try sometime if you want something low maintenance and you can see what all of the fuss is about. You’ll be happy that you did!
