The tuberous geranium plants are actually different from the familiar geranium which we all know and love. The well-known scented geraniums are actually not true geraniums. The scented geraniums are pelargoniums. The Tuberous geraniums which is also known as hardy geraniums, cranesbill or wild geraniums, are their slightly wild cousins. The pelargoniums growing in a container on your patio are annuals, while the tuberous geranium plants are actually perennials. Even though the two plants are related, they are very different. For beginners, the tuberous geranium plants vary substantially from pelargonium in color, shape, and blooming habits. As the name implies, the tuberous geranium plants actually spread via underground tubers. In spring, clumps of rosy lavender blooms marked with dark purple veins rise on wiry stems above lacy-looking foliage. The seedpod that appears at the end of the season really looks like crane’s beaks, thus the name “cranesbill.”
