It has an upright growth habit with branched stems that are covered with small, succulent-like leaves. The leaves are oval-shaped, about 4 cm long and 2 cm wide, and have prominent veins. The upper surface of the leaves is dark green, while the lower surface is paler and hairy. The plant's most striking feature is its uniquely patterned leaves, which have dark purple spots and margins, giving them a distinct appearance.
Uses

Pennyroyal Plectranthus is also believed to have medicinal properties and is used in traditional medicine to treat conditions such as headaches, stomach ailments, and respiratory infections. Additionally, its fragrant leaves are known to repel insects, making it an excellent natural insecticide.
Light Requirements
The Plectranthus rubropunctatus Codd plant requires bright, indirect light. It is not recommended to expose the plant to direct sunlight as it may burn the leaves. Placing the plant near a window that is shaded by a sheer curtain is an ideal spot for it to grow.
Temperature Requirements
The Plectranthus rubropunctatus Codd plant grows best in warm temperatures ranging from 18 to 26 degrees Celsius. It can also tolerate cooler temperatures but not below 10 degrees Celsius. It is vital to ensure that the plant is not exposed to cold drafts, which may cause the leaves to wither and eventually lead to its death.
Soil Requirements
The Plectranthus rubropunctatus Codd plant prefers well-draining soil that is mixed with perlite or sand. A suitable soil mixture should have adequate nutrients to promote growth. The pH level should range from 6 to 7.5, which is slightly acidic to neutral. Overwatering causes the roots to rot and eventually kills the plant. It is recommendable to let the soil dry out before watering, and watering should only be done when the topsoil feels dry to the touch.
Cultivation
The Plectranthus rubropunctatus Codd plant is native to South Africa, where it thrives in warm and humid environments. When cultivating this plant, it is essential to provide it with similar conditions. The plant requires bright but indirect sunlight, with temperatures ranging between 60 and 75 F (15-24 C).
Plectranthus rubropunctatus Codd plants grow well in well-draining soils that have high moisture retention. Gardeners should mix coarse sand or perlite into the soil to improve drainage. The plant grows best in slightly acidic soil (pH 6.1 - 6.5).
Watering Needs
This plant requires thorough watering, but it is essential to allow the soil to dry between watering. Overwatering can cause root rot, which can be detrimental to the Plectranthus rubropunctatus Codd plant. Experts recommend using rainwater since the plant is sensitive to hard water with high salt levels.
Fertilization
Using a slow-release fertilizer, gardeners can fertilize the Plectranthus rubropunctatus Codd plant monthly during the growing season. Avoid using synthetic fertilizers, which can build up salts in the soil and cause root burn. Preferably, organic fertilizers are ideal for this plant since it's gentle on their leaves and stems.
Pruning
To keep the Plectranthus rubropunctatus Codd plant growing compactly and bushy, prune it regularly. Pinch off the tips of the stems to encourage the plant to grow fuller. Gardeners can remove any yellowing or spent leaves or stems to keep the plant looking healthy. It's crucial to disinfect pruning tools before and after each cut to prevent cross-contamination or the spread of diseases in the plant.
Propagation Methods for Plectranthus rubropunctatus Codd

- Divide the root ball into two or more sections, ensuring that each section has some healthy roots and several stems.
- Plant each section in a suitable container or ground, ensuring that the top of the root ball is level with the soil surface.
- Water the plants lightly and keep them in shaded, warm conditions. Maintain the soil's moisture level to help the roots establish.
- After a few weeks, the plant should begin to produce new leaves and grow quickly.
Propagation by Seeds
Propagation by seeds is another option for the Plectranthus rubropunctatus Codd. Here are the steps to follow:
- Collect the ripe seeds from a mature plant and leave them in a warm location for some time to dry out.
- Purchase some seed-raising mix and plant the seeds just below the soil surface.
- Maintain a warm and moist environment, ensuring that the soil remains moist but not soaked.
- After a few days, the seeds should start to germinate, and new seedlings will emerge.
- When the seedlings reach the size of 2-3 inches, transplant them into individual pots and begin to fertilize them according to the manufacturer's instructions.
- After the seedlings have grown adequately, transplant them outdoors in suitable locations and continue to care for the plants as required.
By using these different propagation methods, you can multiply the delightful Plectranthus rubropunctatus Codd quickly and effortlessly.
