Imperial Geraniums: Majestic Stars of Spring
Have you ever heard of Regal pelargoniums, also known as macrantha?
Many consider them the true "kings of geraniums", and it's not hard to see why. With their elegant habit and spectacular blooms, they represent one of the most fascinating categories of the entire Pelargonium genus.
Likely originating from the species Pelargonium grandiflorum and Pelargonium cucullatum, these geraniums spread thanks to the work of 19th-century hybridizers and reached their peak during the Victorian era. Their genealogy, however, still retains some unclear aspects today, due to the numerous confusions that have occurred over time in botanical classification.
Large, elegant, and spectacular flowers
If there's one characteristic that makes Regal pelargoniums immediately recognizable, it's undoubtedly their flowers.
Large, velvety, and showy, they can reach sizes almost three times larger than traditional zonal geraniums.
The range of colors is also surprising:
- intense pinks
- deep purples
- pastel shades
- bicolor tones
- varieties with very dark, almost black colors
It's no coincidence that in Anglo-Saxon countries they are often also called "azalea geraniums", due to the resemblance of their blooms to those of ornamental azaleas.
The right pot makes all the difference
To allow these plants to express their full potential, it is advisable to grow them in sufficiently large containers.
Generally, a pot of at least 16-18 cm in diameter is recommended, which allows the roots to develop properly and the plant to support flower production.
A brief but intense bloom
Unlike other types of geraniums, macrantha do not like excessively intense sun or very high temperatures.
Their ideal season is spring, during which they offer maximum flowering.
With the arrival of summer heat, flower production generally tends to decrease or stop.
In hilly and mountainous areas, where summer temperatures remain milder, they can, however, continue to bloom, albeit discontinuously, until autumn.
A historical presence in Italian gardens
In some Italian regions, particularly in Sicily and Calabria, it is still possible to find old specimens of Regal pelargoniums grown in courtyards, terraces, balconies, and even flowerbeds.
These are often varieties handed down over time, without a precise commercial name, but still capable of charming today with their elegance and generosity.
These plants represent a living testament to the long history of ornamental pelargoniums in our country.
The protagonists of the Victorian era
During the Victorian era, Regal pelargoniums became absolute protagonists of English gardens.
Hybridizers of the time enthusiastically dedicated themselves to selecting new varieties, creating hundreds of different cultivars in terms of flower color, shape, and size.
Many of those historical selections have been lost, but numerous varieties continue to be cultivated and appreciated by enthusiasts worldwide today.
Why choose a Regal pelargonium
Regal pelargoniums are ideal for those looking for:
- large and spectacular blooms
- intense and refined colors
- a plant that is a star of spring
- historical varieties with timeless charm
Their blooming period may be shorter than other categories of pelargoniums, but the beauty of their flowers amply repays the wait.
