Overview: Pelargonium (Geranium) and Its Varieties
The Pelargonium genus encompasses around 230 species, most of which originate from South Africa. The name "Pelargonium" is derived from the Greek word pelargos ("stork"), alluding to the fruit's distinctive stork-beak shape.
With a vast variety of hybrids available, pelargoniums have become cherished houseplants—especially when given plenty of light, as this helps them thrive and flower prolifically indoors or on balconies.
Main Groups of Pelargoniums
Pelargoniums are generally grouped into four main categories, each featuring unique characteristics:
- Zonal Pelargoniums: Noted for the dark-colored bands or "zones" on their leaves.
- English Pelargoniums: Distinguished by their pansy-like, multicolored flowers.
- Rose Pelargoniums: Appreciated for their aromatic, fragranced leaves.
- Trailing (Ivy-Leaved) Pelargoniums: Particularly suited for hanging baskets and balcony containers, these varieties can also be trained on small trellises and prefer a bright, cooler spot indoors.
Trailing Pelargoniums: ‘Crocodile’ and Other Favorites
Trailing pelargoniums—sometimes called ivy-leaved pelargoniums—have experienced great popularity due to their dazzling abundance of blooms and cascading habit. These plants are ideal for an amplifier (hanging basket) or balcony box and can even be encouraged to climb a modest support. Indoors, they flourish in bright, cool conditions and can bring a touch of the outdoors into your home environment.
Standout Trailing Varieties
Among trailing pelargoniums, here are some standout varieties:
- CROCODILE: This remarkable variety gets its name from its leaves, which are adorned with markings reminiscent of crocodile skin—a unique and attractive feature for any collection.
- JACKY GAULD: An exquisite variety with large, fully double, rose-shaped flowers in a rosy lilac hue. Its striking blooms make it a memorable addition.
- BONITO: Offers double, dark wine-red flowers brightened by contrasting white edges.
- ROULETTA/MEXICANA: One of the best-known trailing types, easily recognized by its unforgettable striped red-and-white blooms.
- L’ÉLEGANTE (introduced in 1868): Features ivy-shaped leaves with white borders that blush soft pink in sunny locations—both decorative and historic.
Cultivation Tips
Trailing pelargoniums require similar care to other pelargoniums: water and fertilize them occasionally, and they will respond with vigorous growth. During winter, they should be kept in a bright location and watered sparingly. With just a little attention, trailing pelargoniums reward you with season after season of flowers and lush foliage.
