Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water moderately when the top 2-3 cm of soil feels dry. Avoid waterlogging, as this can lead to root rot. Ensure good drainage. Reduce watering slightly during winter dormancy.
Keep the soil consistently moist but not saturated for optimal growth.
Pinch back young plants to encourage bushier growth. Remove spent flowers regularly to promote continuous blooming and prevent self-seeding.
Trim leggy stems in late summer or early autumn to maintain a tidy shape and encourage new growth for the following season.
Easily propagated from seed sown in spring or autumn, or by stem cuttings taken in late spring or early summer. Cuttings should be rooted in a well-draining potting mix, kept moist, and placed in a warm, bright location out of direct sun.
Repot every 1-2 years in spring, or when the plant becomes root-bound. Use a well-draining potting mix. Choose a pot only slightly larger than the current one to avoid excessive moisture retention.
Ensure the pot has drainage holes.
