WaterThe Plumbago auriculata, also known as Cape Leadwort, should be watered thoroughly when the top inch of soil feels dry to the touch. Depending on the environment, this may result in watering every few days during the active growing season, typically spring and summer. It's best to use long, deep waterings rather than frequent shallow ones to encourage deep root growth, which might amount to around 1-2 gallons for a medium-sized outdoor plant every week. During winter, reduce watering to every couple of weeks or less, as the plant's water requirements decrease significantly.
LightPlumbago auriculata thrives in full sun to partial shade. The ideal spot would be where it can receive at least six hours of direct sunlight balanced with some dappled shade during the hottest part of the day. A south or west-facing location where the light is bright and ample would be perfect for this plant to encourage robust flowering.
TemperaturePlumbago auriculata grows best in temperatures that range from 35 to 90 degrees Fahrenheit. It can survive minimum temperatures down to about 20 degrees Fahrenheit but prefers not to stay in the cold for extended periods. Keep in mind, the ideal growing conditions are within the 60 to 75 degrees Fahrenheit range, and consistent temperatures below the minimum can be detrimental to the plant's health.
PruningPruning the Plumbago auriculata, or Cape Leadwort, is essential for controlling its shape and size, and for encouraging prolific blooming. Prune in late winter or early spring before the new growth begins. Remove any dead or damaged wood, and cut back up to one-third of the plant to maintain a dense, bushy form. It will also benefit from light pruning throughout the growing season to remove spent flowers and promote continuous blooming.
CleaningAs needed
SoilThe best soil mix for Plumbago auriculata, commonly known as Leadwort, is well-draining soil with a mix of loam, sand, and compost. It prefers a soil pH between 5.5 and 7.5. Amending the soil with organic material will improve growth and flowering.
RepottingLeadwort should be repotted every 2 to 3 years to refresh the soil and promote healthy growth. Springtime is the best period for repotting. Care should be taken to not damage the root system during this process.
Humidity & MistingLeadwort thrives in average room humidity levels but can tolerate lower humidity without adverse effects. It does not require high humidity to grow successfully, making it versatile for varying home environments.
Suitable locationsIndoor
Ensure bright light, well-draining soil, and regular watering for indoor Leadwort.
Outdoor
Plant in sun to part shade, well-draining soil, and water regularly for outdoor Leadwort.

Life cycleCeratostigma griffithii, commonly known as Griffith's plumbago, begins its life cycle with seed germination, usually carried out in spring under the right temperature and soil moisture conditions. Once the seeds germinate, they develop into seedlings, which then mature into young plants with a characteristic bushy growth habit. As the plants grow, they produce oblong to lance-shaped green leaves and clusters of deep blue to violet flowers, typically from late summer to autumn. After pollination, primarily by insects, the flowers develop into capsules containing the seeds. The plant may also spread through rhizomes, leading to new shoots emerging from the soil around the parent plant. In winter, the plant goes into a period of dormancy, with leaves often turning a vibrant red or purple before shedding, and it remains dormant until the next growing season.
PropogationPropogation time
Spring to summer
The most popular method of propagation for the Dwarf Plumbago (Ceratostigma griffithii) is by semi-hardwood cuttings. The ideal time for taking cuttings is in the late summer when growth has partially matured but is not fully hardened. Cut a 4 to 6 inch (10 to 15 cm) section of stem that includes several leaves. Dip the cut end in rooting hormone powder to encourage root development. Then, plant the cutting in a well-draining potting mix, ensuring that at least one set of leaves is above the soil surface. Place the pot in a warm, bright area but out of direct sunlight and keep the soil consistently moist. Roots typically establish within several weeks, after which the cuttings can be transplanted into the garden or individual pots.
