Outdoor Cultivation of Regal Geranium
Pelargonium grandiflorum (Andrews) Willd.
Growing Regal Geranium outdoors requires protection from precipitation and wind due to the fragility of its large flowers and specific temperature requirements for bud initiation.
In the reference 4 varieties crop Regal pelargonium, where this is mentioned in the description.
For Regal Geranium (Pelargonium grandiflorum), outdoor cultivation is best suited to a mobile format—using containers or hanging baskets that can be moved to a sheltered area. The plant is sensitive to precipitation, which causes flower rot, and strong winds; therefore, it is not recommended to plant it in open, exposed areas.
When placing the plant in a garden, it is necessary to select sites with light partial shade, as intense midday sun negatively affects the crop's condition. An important biological requirement is a cool period with temperatures of 5–15 °C, which is necessary for floral bud initiation; this limits the use of the plant as a conventional garden annual.
