Kangaroo Paw vs Physostegia Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Kangaroo Paw
Anigozanthos spp.
Kangaroo Paw is a genus of Australian native plants known for their unique flowers that resemble the paws of kangaroos. These perennial plants feature clumps of strap-like leaves and tall flower stalks bearing tubular, velvety flowers in vibrant colors like red, green, yellow, orange, and pink. Primarily outdoor plants, they thrive in sunny, well-drained conditions. People grow them for their striking architectural form, unusual flowers, and ability to attract birds and pollinators to the garden. Indoor cultivation is challenging due to high light requirements.
Physostegia
Physostegia virginiana
Physostegia virginiana, commonly known as Obedient Plant, is a herbaceous perennial native to North America. It features upright, square stems and lance-shaped, toothed leaves. The plant is known for its unique flowers that bloom in late summer and fall, forming dense spikes of tubular, pink, lavender, or white blossoms. The common name comes from the fact that if you gently push a flower to one side, it will often stay in that position. It is primarily an outdoor plant, valued for its late-season blooms and ability to attract pollinators. It can be challenging to grow indoors due to its high light requirements and tendency to spread.

❓ Frequently Asked Questions — Comparing These Plants
Kangaroo Paw
What are the light requirements for Kangaroo Paw?
Kangaroo Paws thrive in full sun, needing at least six hours of direct sunlight per day to produce abundant blooms. An east or south-facing window is ideal for indoor plants. Insufficient light can result in leggy growth and reduced flowering. If natural light is limited, supplement with a grow light. Rotate the plant regularly to ensure even light exposure. In hot climates, provide some afternoon shade to prevent leaf scorch. Monitor the plant for signs of light stress, such as pale leaves or stunted growth. Adjust its location as needed to provide optimal lighting conditions.
How do I care for Kangaroo Paw?
Kangaroo Paws require full sun and well-draining soil. Water deeply but infrequently, allowing the soil to dry out between waterings. Fertilize during the growing season (spring and summer) with a low-phosphorus fertilizer to encourage flowering. Prune spent flower stems to promote new growth. Protect from frost in colder climates. Repot every 2-3 years in spring. Ensure good air circulation to prevent fungal diseases. Regularly check for pests like aphids and spider mites. Use a native Australian potting mix if possible. Monitor humidity levels and increase if needed. Avoid overwatering, which can lead to root rot. Provide support for taller varieties to prevent them from flopping over.
How do I propagate Kangaroo Paw?
Kangaroo Paw can be propagated by division or seed. Division is best done in spring. Carefully dig up the plant and divide the rhizomes into separate clumps, ensuring each clump has healthy roots and foliage. Replant the divisions in well-draining soil. Seeds can be sown in spring. Soak seeds in warm water overnight before sowing. Sow seeds in a well-draining seed-starting mix and keep moist. Germination can be slow and irregular. Stem cuttings are difficult but may work in some instances. Allow the cut to callous over for several days before planting in well-draining soil. Keiki propagation is not applicable to Kangaroo Paw.
Physostegia
What are the light requirements for Physostegia?
Physostegia prefers full sun, which translates to at least six hours of direct sunlight per day. In hotter climates, some afternoon shade can be beneficial to prevent scorching. Insufficient light can lead to leggy growth and reduced flowering. When growing Physostegia indoors (less common), place it near a sunny window, such as a south-facing exposure. Rotate the plant regularly to ensure even light distribution. Be mindful of the intensity of the sunlight, especially during peak summer months, as too much direct sun can also damage the foliage. Observe the plant’s growth and adjust its position accordingly to provide optimal light conditions.
How do I care for Physostegia?
Physostegia thrives in full sun to partial shade, requiring at least six hours of sunlight daily for optimal blooming. Water regularly, especially during dry spells, keeping the soil consistently moist but not waterlogged. Well-draining soil is essential to prevent root rot. Fertilize in early spring with a balanced fertilizer to promote healthy growth and abundant blooms. Deadhead spent flowers to encourage continuous blooming throughout the summer. Physostegia can spread aggressively, so consider planting it in a container or using barriers to control its growth. Divide clumps every few years to maintain vigor and prevent overcrowding. Monitor for common pests like aphids and spider mites, and treat as needed.
How do I propagate Physostegia?
Physostegia can be easily propagated through division. In early spring or fall, carefully dig up the plant and divide the root clump into smaller sections, ensuring each section has healthy roots and shoots. Replant the divisions in well-draining soil. Stem cuttings can also be taken in late spring or early summer. Take 4-6 inch cuttings from new growth, remove the lower leaves, and dip the cut end in rooting hormone. Plant the cuttings in a moist potting mix and keep them humid until rooted. Physostegia does not produce keikis.
