Pennisetum setaceum

Fountain Grass is a perennial grass known for its graceful, arching foliage and bottlebrush-like flower plumes. Typically grown as an ornamental grass, it adds texture and movement to landscapes. It forms dense clumps of slender, linear leaves that can range in color from green to reddish-purple, depending on the cultivar. The feathery flower plumes emerge in summer and persist into fall, adding visual interest. While primarily an outdoor plant, it is sometimes grown in containers. It is valued for its drought tolerance and low maintenance requirements in suitable climates.

Kangaroo Paw

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.

📅 Maintenance Schedule — Plant Care Comparison

Fountain Grass

Repotting Not typically repotted if grown outdoors. If grown in containers, repot every 1-2 years in spring.
Pruning Cut back foliage in late winter or early spring before new growth emerges. Deadhead spent flower plumes to maintain appearance and prevent unwanted seed dispersal.
Fertilizing Apply a balanced slow-release fertilizer in spring. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowering.
Seasonal Care In winter, cut back foliage to a few inches above the ground in colder climates. In summer, ensure adequate watering during dry spells.

Kangaroo Paw

Repotting Not applicable for indoor growing as it is not recommended. If grown in a container outdoors, repot every 2-3 years in spring.
Pruning Remove spent flower stalks and dead leaves to encourage new growth and maintain appearance.
Fertilizing Native plant fertilizer or a low-phosphorus fertilizer, diluted to half strength. Apply in spring and early summer.
Seasonal Care In winter, reduce watering and protect from frost. In summer, ensure adequate watering and sun protection during heatwaves.

💡 Pro Tips For Comparing These Plants

Fountain Grass Care Tips

Fountain Grass is primarily an outdoor plant that thrives in full sun and well-draining soil. Growing it indoors is challenging due to its high light requirements and potential size. It requires careful watering and fertilization. It can become invasive in some regions due to its prolific seed production.

  • Plant in well-draining soil to prevent root rot.
  • Provide full sun for optimal growth and flowering.
  • Water deeply but infrequently, allowing the soil to dry out slightly between waterings.
  • Cut back foliage in late winter or early spring to encourage new growth.
  • Deadhead spent flower plumes to prevent unwanted seed dispersal.
❄️ Winter: In colder climates, cut back foliage to a few inches above the ground in late winter or early spring. Mulch around the base of the plant to protect the roots from freezing temperatures.
☀️ Summer: Ensure adequate watering during dry spells. Deadhead spent flower plumes to maintain appearance and prevent unwanted seed dispersal. Monitor for pests and diseases.

Kangaroo Paw Care Tips

Kangaroo Paw is primarily an outdoor plant that requires full sun and well-drained soil. Indoor cultivation is extremely challenging due to the need for intense light, which is difficult to replicate. Even with supplemental lighting, flowering is unlikely. Requires careful watering to avoid root rot.

  • Ensure excellent drainage to prevent root rot.
  • Provide full sun for optimal flowering.
  • Prune regularly to remove spent flower stalks and dead leaves.
  • Fertilize sparingly with a low-phosphorus fertilizer.
  • Protect from frost in colder climates.
❄️ Winter: Reduce watering during the winter months as the plant's growth slows down. Protect from frost by mulching around the base of the plant or moving container plants to a sheltered location.
☀️ Summer: Ensure adequate watering during hot summer months, especially during heatwaves. Provide some afternoon shade in extremely hot climates to prevent leaf scorch.

❓ Frequently Asked Questions — Comparing These Plants

Fountain Grass

What are the light requirements for Fountain Grass?

Fountain Grass requires a minimum of six hours of direct sunlight each day to thrive and produce abundant blooms. Insufficient light can lead to weak growth, fewer flowers, and a generally unhealthy appearance. When planting Fountain Grass, choose a location that receives full sun exposure throughout the day.

How do I care for Fountain Grass?

Fountain Grass thrives in full sun and well-drained soil. Water deeply but infrequently, allowing the soil to dry out slightly between waterings. Fertilize in spring with a balanced fertilizer to promote healthy growth and abundant blooms. Prune back dead foliage in late winter or early spring before new growth emerges.

How do I propagate Fountain Grass?

Fountain Grass is easily propagated by division. In early spring, carefully dig up the clump and divide it into smaller sections, ensuring each section has healthy roots and foliage. Replant the divisions in well-drained soil and water thoroughly. Stem cuttings are not a reliable method. Keikis do not naturally occur on Fountain Grass.

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.
