A Complete Guide to the Characteristics and Care of Regal Pelargoniums

The regal pelargonium is a perennial herbaceous plant in the genus Pelargonium of the family Geraniaceae, also known as the garden geranium or butterfly pelargonium, and is a horticultural group bred by crossing several original species. Its plants grow in compact clumps, with nearly round or kidney-shaped leaves that have shallow lobes along the edges. The flowers are large and striking, and the petals often carry dark markings or veins. Flower colors cover many shades including pink, red, purple and white, with blooming most concentrated in spring.

Compared with the common zonal pelargonium, the regal pelargonium has larger flowers and wider petals, the ring markings on the leaves are generally not obvious, and the overall plant form is more upright. In horticulture it has many cultivars, and different cultivars differ noticeably in flower color, markings and plant height, so they can be chosen according to the space available and personal preference.

For care, it prefers a cool environment with plenty of light and good ventilation, and it fears high temperatures and high humidity. In summer it often enters a semi-dormant state, so it needs appropriate shading, controlled watering and maintained air circulation. During the growing period, water by letting the soil dry between waterings, and avoid water accumulating in the pot. Before buds form and flowering begins, some phosphorus and potassium fertilizer can be added. After flowering, promptly cut off spent flowers and overly dense branches, which helps keep the plant form neat and benefits flowering the following year.

Propagation is mainly by cuttings. In spring and autumn, select strong branches for cuttings, which gives a relatively high survival rate. The regal pelargonium has elegant flowers and rich colors, making it suitable for growing in pots placed on windowsills, balconies or in courtyards, and it is a common choice for decorating homes and courtyard gardens in spring.
