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.”
How to Plant Tuberous Geraniums
The Tuberous geraniums plant are suitable
for growing in USDA plant hardiness zones five through nine, the tuberous
geranium plants may look delicate, but they are actually very tough. The
Tuberous geraniums plants are also easy to grow. To grow Tuberous geraniums choose
a planting location carefully. The flowers can be rambunctious, so make sure
they have room to spread. The Tuberous geraniums plants tolerate nearly any
soil, but they actually perform best in moderately fertile, well-drained soil –
much like conditions in their natural environment. Full sun is really okay, however
a little shade or dappled sunlight is best, most especially if you live in a
climate with hot summers. Plant the tubers about four inches deep in spring or
fall. Make sure you water well after planting. The Tuberous geranium plants are
also drought tolerant once they are established. You can easily remove wilted
blooms (deadhead) to extend the blooming period. The tuberous geraniums plants are
cold hardy, but a generous layer of mulch such as compost, chopped leaves, or
fine bark will protect the roots of the plant during the winter.
