Catnip vs Plumbago Auriculata Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Catnip
Nepeta cataria
Catnip is a herbaceous perennial plant known for its intoxicating effect on cats. It typically grows to a height of 50-100 cm, featuring grayish-green, heart-shaped leaves with serrated edges. The plant produces spikes of small, white or pale lavender flowers dotted with purple spots. While primarily grown outdoors, it can be cultivated indoors with sufficient light. People grow it for its appeal to cats, its use in herbal teas, and its purported medicinal properties.
Plumbago Auriculata
Plumbago auriculata
Plumbago auriculata is a sprawling, evergreen shrub known for its profuse clusters of phlox-like, pale blue flowers. It typically grows to 6-10 feet tall and wide in its native habitat but is often smaller in cultivation, especially when grown in containers. The plant features light green, oval-shaped leaves. While it can be grown in containers, it thrives outdoors in warm climates. People grow it for its attractive flowers, long bloom season, and relatively easy care in suitable climates. It is primarily an outdoor plant.

❓ Frequently Asked Questions — Comparing These Plants
Catnip
What are the light requirements for Catnip?
Catnip requires a minimum of six hours of direct sunlight each day to thrive. Insufficient light can result in leggy growth and reduced flowering. A south-facing window is ideal for indoor Catnip, providing ample sunlight throughout the day. If natural light is limited, supplement with grow lights, positioning them about 6-12 inches above the plant. Rotate the plant regularly to ensure even light exposure on all sides. Monitor the leaves for signs of sunburn, such as scorched spots, if the light is too intense. Adjust placement or provide shade as needed. Adequate light is crucial for photosynthesis and overall plant health.
How do I care for Catnip?
Catnip thrives in well-draining soil and requires at least six hours of sunlight daily. Water thoroughly when the top inch of soil feels dry, but avoid overwatering to prevent root rot. Fertilize sparingly with a balanced, slow-release fertilizer in the spring to encourage healthy growth and blooming. Prune regularly to maintain a compact shape and promote bushier growth. Catnip is relatively low-maintenance but benefits from occasional deadheading to encourage further flowering. Protect from extreme cold during winter months, especially in colder climates. Indoor plants need good air circulation. Monitor for pests like aphids and spider mites, and treat promptly. Choose a pot with drainage holes.
How do I propagate Catnip?
Catnip can be easily propagated through stem cuttings, division, or seeds. For stem cuttings, take a 4-6 inch cutting from a healthy stem, remove the lower leaves, and place it in water or directly into moist soil. Roots should develop within a few weeks. For division, carefully dig up the plant and separate the root ball into smaller sections, ensuring each section has healthy roots and foliage. Replant the divisions in separate pots. Seeds can be sown directly into the garden or started indoors. Keep the soil moist until germination occurs. Propagation is best done in spring or early summer.
Plumbago Auriculata
What are the light requirements for Plumbago Auriculata?
Plumbago Auriculata needs at least six hours of direct sunlight per day to produce abundant blooms. In hotter climates, provide some afternoon shade to prevent scorching of the leaves. An east-facing location that receives morning sun and afternoon shade is ideal. Insufficient light will result in fewer flowers and leggy growth. If growing indoors, place the plant near a sunny window, preferably south-facing. Rotate the plant regularly to ensure even light exposure on all sides. Supplemental lighting may be necessary during the winter months or in areas with limited sunlight. Monitor the plant for signs of light stress, such as pale leaves or lack of blooms, and adjust its location accordingly.
How do I care for Plumbago Auriculata?
Plumbago Auriculata thrives in full sun to partial shade. Water thoroughly when the top inch of soil feels dry to the touch; avoid overwatering to prevent root rot. Use well-draining soil. Fertilize monthly during the growing season (spring and summer) with a balanced fertilizer to promote abundant blooms. Prune regularly to maintain shape and encourage bushier growth; remove spent flowers to stimulate further blooming. In colder climates, provide winter protection by moving potted plants indoors or covering in-ground plants with mulch. Check for pests regularly, such as aphids or spider mites, and treat accordingly with insecticidal soap. Maintain good air circulation around the plant to prevent fungal diseases. Repot as needed when the plant becomes root-bound. Plumbago benefits from occasional deadheading.
How do I propagate Plumbago Auriculata?
Plumbago Auriculata can be propagated through stem cuttings. Take 4-6 inch cuttings from new growth in the spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in well-draining potting mix. Keep the soil moist and provide bright, indirect light. Roots should develop within a few weeks. Division of established plants can also be done in spring. Gently separate the root ball and replant each section. Keiki propagation is not applicable to this species.
