Pickerel Weed vs Sensitive Plant Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Pickerel Weed
Pontederia cordata
Pickerelweed is an aquatic perennial herb typically found in shallow water habitats like ponds, marshes, and streams. It features distinctive heart-shaped leaves and a prominent flower spike that blooms in summer. The plant grows from rhizomes, forming dense colonies. While primarily an outdoor plant, it is occasionally grown in large water gardens or aquariums. It is valued for its attractive foliage and flowers, which attract pollinators and provide habitat for aquatic wildlife.
Sensitive Plant
Mimosa pudica
Mimosa pudica, commonly known as the Sensitive Plant, is a fascinating perennial often grown as an annual. It's characterized by its compound leaves that dramatically fold inward and droop when touched or shaken, a defense mechanism against herbivores. The plant features small, globular pink or lavender flower heads. While it can be grown indoors, it thrives best outdoors in warm climates. People grow it for its unique and interactive response to touch, making it a popular novelty plant. It has a somewhat sprawling growth habit.

💧 Watering Needs
Pickerel Weed
Requires consistently moist to wet conditions. If grown in a container, ensure the pot is sitting in a tray of water or submerged in a larger water feature. Overwatering is not a concern as it is an aquatic plant. Underwatering will cause the leaves to wilt and brown.
Sensitive Plant
Water thoroughly when the top inch of soil feels dry. Avoid overwatering, which can lead to root rot. Signs of overwatering include yellowing leaves and a soggy soil. Underwatering will cause the leaves to droop and become crispy.

💡 Pro Tips For Comparing These Plants
Pickerel Weed Care Tips
Pickerelweed is best suited for outdoor water gardens or large aquariums. It requires full sun and consistently wet conditions. Indoor cultivation is challenging due to the need for specialized aquatic environments and intense lighting. It is an aggressive spreader and needs containment.
- Ensure consistent water levels, especially during hot weather.
- Provide full sun for optimal flowering.
- Use aquatic plant fertilizer to promote healthy growth.
- Control algae growth to prevent it from smothering the plant.
- Protect rhizomes from freezing in colder climates.
Sensitive Plant Care Tips
Mimosa pudica requires bright light and consistent moisture. While it can be grown indoors, providing enough sunlight is crucial for its health. The plant is sensitive to overwatering and cold temperatures. Its unique response to touch makes it a fun plant to grow, but be mindful of its toxicity to pets.

❓ Frequently Asked Questions — Comparing These Plants
Pickerel Weed
What are the light requirements for Pickerel Weed?
Pickerel Weed thrives best in full sun, requiring at least six hours of direct sunlight daily. However, it can also tolerate partial shade, especially during the hottest part of the day. Insufficient light can lead to leggy growth, reduced flowering, and overall weaker plants.
How do I care for Pickerel Weed?
Pickerel Weed thrives in shallow water or moist soil. Plant in a pond, water garden, or a container submerged in water. Full sun to partial shade is ideal. Ensure the water is clean and well-oxygenated. Add aquatic plant fertilizer sparingly during the growing season (spring and summer). Remove dead leaves and flowers regularly.
How do I propagate Pickerel Weed?
Pickerel Weed can be easily propagated through division or cuttings.
Sensitive Plant
What are the light requirements for Sensitive Plant?
The Sensitive Plant needs bright, indirect light to flourish. A south-facing or east-facing window is ideal, providing ample light without direct sunlight, which can scorch the leaves. If natural light is insufficient, supplement with a grow light, placing it 12-18 inches above the plant. Rotate the plant regularly to ensure even light exposure on all sides. Insufficient light can lead to leggy growth, reduced blooming, and loss of sensitivity. Monitor the plant’s response to light and adjust its position accordingly. During the winter months, when light levels are lower, consider increasing the duration of artificial lighting to maintain healthy growth.
How do I care for Sensitive Plant?
Mimosa pudica thrives in bright, indirect light, requiring at least 6 hours daily. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain a temperature between 65-80°F (18-27°C) and a humidity level of 50-60%. Fertilize every 2-4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength, focusing on a formula that encourages blooming. Use well-draining potting mix. Repot in spring if the plant becomes root-bound. Avoid over-handling the plant, as excessive touching can stress it. Prune lightly to maintain shape and remove dead or yellowing leaves. Provide support if the plant becomes leggy. Watch for pests like spider mites and aphids, and treat promptly. Proper care will reward you with healthy growth and beautiful blooms.
How do I propagate Sensitive Plant?
Sensitive Plants can be propagated from seeds or stem cuttings. For seeds, scarify the seeds and soak them in warm water for 24 hours before sowing in a moist seed-starting mix. Keep them warm and humid until germination, which usually takes 1-3 weeks. For stem cuttings, take a 4-6 inch cutting from a healthy stem, remove the lower leaves, and dip the cut end in rooting hormone. Plant the cutting in a moist potting mix and cover it with a plastic bag to maintain humidity. Place it in a warm, bright location, avoiding direct sunlight. Roots should develop in 2-4 weeks. Keiki propagation is not applicable to this plant.
