Pelargonium quercifolium
oak-leaved geranium (syn. P. 'Karrooense')
A delicate evergreen species with stems that are initially soft and covered in fine hairs, gradually maturing into a woody sub-shrub over time.
The deeply lobed leaves possess a slight stickiness and emit a pleasant balsam fragrance, with each leaf displaying dark zonal markings, adding to its visual appeal.
During late spring and summer, clusters of lilac pink flowers with reddish-purple markings grace the plant. Notably, Pelargonium quercifolium is considered one of the hardier varieties within the pelargonium family.
It can overwinter at a relatively cool temperature of around 6°C. However, if provided with higher temperatures and abundant sunlight, it will continue to flourish and bloom even during the winter months.

How to care for Pelargonium quercifolium:
Pot up in free-draining compost and grow them on in a bright, frost-free spot. Move plants outside only after all risk of frost has passed, placing them in a sunny, sheltered position. Water regularly, allowing the surface to dry slightly between waterings, as they dislike being constantly wet. Remove faded flowers and yellowing leaves to keep plants tidy and to encourage more blooms.
Feed every couple of weeks through the growing season with a dilute high-potash fertiliser such as Tomorite to support flowering. Pinch back leggy growth to maintain a bushy shape, and bring plants back indoors before autumn frosts if you wish to overwinter them.
