Cultivation

Bedding plants — Pelargonium (hybrids)

hybrids between Pelargonium peltatum and Pelargonium zonale

Interspecific Pelargonium hybrids represent a group of plants adapted for outdoor cultivation due to their high tolerance to weather stress and prolonged flowering.

In the reference 5 varieties crop Ivy-leaved geranium, where this is mentioned in the description.

Interspecific hybrids, derived from crossing Pelargonium peltatum and Pelargonium zonale, differ from zonal pelargoniums by increased hardiness to extreme temperatures, high humidity, and short-term drought. They form a robust, semi-upright or spreading habit, which allows for effective coverage of flower bed areas.

These hybrids possess self-cleaning properties, which minimizes the need for deadheading when landscaping large areas. Unlike trailing forms, these plants maintain plant structure and demonstrate higher resistance to diseases, particularly Botrytis, ensuring consistent flowering from spring until the first frosts.

For the establishment of high-quality outdoor mass plantings, the planting density of the hybrids is approximately 12–14 plants per square meter, with adjustments made based on the growth vigor of a specific variety. Optimal plant development is achieved in well-drained substrates with regular watering and balanced application of phosphorus-potassium fertilizers with limited nitrogen.
