People often get confused about Geraniums. For many, Geraniums are red or pink annuals with a rather weird scent that you put in pots every summer. While that is true in one sense, those “geraniums” actually have the botanical name of Pelargonium. It’s an example of why it’s helpful to know the botanical name in order to make sure people are talking about the same thing, as the habit and care of those two plants could not be more different.
The true Geranium (Often called ‘Cranesbill’, just to confuse things) is a perennial, whereas Pelargoniums are annuals in the Northeast. They look a lot different, too, with Geraniums forming mounds of sedate foliage covered in five petaled flowers in pink, white, magenta, or purplish blue, Pelargoniums having thick, leathery foliage and clusters of red, pink, salmon, or white flowers borne on stalks. Geraniums nestle right into a garden border, whereas Pelargoniums seem more at home in pots.
Geraniums are wonderful, versatile plants that will bring you weeks, if not months, of blooms in the garden. There is even a native Geranium, Geranium maculatum. Some are as short as 6-8″ like Geranium sanguineum var. striatum, delightful little pale pink one with dark pink veining on the petals. Others are taller, like ‘Blushing Turtle’, which has medium pink flowers and grows to be 18-24″. There are Geraniums with dark bronze foliage and pink flowers (“Espresso’), ones with nodding burgundy flowers with black centers (‘Mourning Widow’) and some with neon pink flowers and white edges (‘Elke’), for example. One of my favorites is one called ‘Azure Rush’. Compact and growing in civilized 18-20” mounds, it has purplish-blue flowers with pale centers that bloom from May through October in my garden.
Try them in the front of the border, spilling onto paths, atop a stone wall… You won’t be sorry.
