Nasturtium Tropaeolum vs Paw Paw Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Nasturtium Tropaeolum
Tropaeolum majus
Tropaeolum majus, commonly known as nasturtium, is an annual flowering plant known for its vibrant, edible flowers and peppery-flavored leaves. It is a sprawling plant that can grow as a ground cover or climb with support. The plant features round, shield-shaped leaves and spurred flowers in shades of orange, yellow, and red. While primarily grown outdoors in gardens and containers for its ornamental value and culinary uses, it can be challenging to maintain indoors due to its high light requirements and sprawling growth habit. People grow it for its bright colors, edible parts, and ability to attract pollinators.
Paw Paw
Asimina triloba
Asimina triloba, the Pawpaw, is a deciduous tree or large shrub native to eastern North America. It typically grows 10-25 feet tall. It features large, oblong leaves that give it a tropical appearance. The tree produces edible fruit, the pawpaw, which is greenish-yellow to brown when ripe and has a creamy texture and flavor reminiscent of banana, mango, and vanilla. Pawpaws are primarily grown for their fruit, which can be eaten fresh or used in desserts and beverages. It is not naturally an indoor plant and requires specific conditions to thrive indoors.

💡 Pro Tips For Comparing These Plants
Nasturtium Tropaeolum Care Tips
Nasturtiums are easy to grow outdoors in sunny locations with well-draining soil. Indoor cultivation is challenging due to high light requirements and the plant's sprawling growth habit. Providing adequate light and avoiding overwatering are crucial for indoor success, which is rarely achieved.
- Provide at least 6 hours of direct sunlight daily for optimal flowering
- Avoid overwatering to prevent root rot
- Use a low-nitrogen fertilizer to encourage flower production
- Pinch back stems to promote bushier growth
- Collect seeds at the end of the season to replant next year.
Paw Paw Care Tips
Pawpaws are challenging to grow indoors due to their need for full sun, specific chilling requirements for fruit production, and large size. They require a very large container, careful watering, and protection from extreme temperatures. Indoor fruiting is unlikely.
- Provide adequate sunlight for optimal fruit production.
- Ensure well-draining soil to prevent root rot.
- Protect young trees from strong winds.
- Water deeply during dry periods.
- Consider hand-pollinating the flowers to improve fruit set.

❓ Frequently Asked Questions — Comparing These Plants
Nasturtium Tropaeolum
What are the light requirements for Nasturtium Tropaeolum?
Nasturtium Tropaeolum thrives in full sun, which translates to at least 6 hours of direct sunlight per day. In hotter climates, provide some afternoon shade to prevent scorching of the leaves and flowers. Insufficient light can lead to leggy growth and reduced blooming.
How do I care for Nasturtium Tropaeolum?
Nasturtium Tropaeolum thrives in well-draining soil and prefers full sun to partial shade. Water regularly, allowing the soil to dry slightly between waterings. Avoid overwatering, which can lead to root rot. Fertilize sparingly, as excessive fertilization can promote leaf growth at the expense of flowers.
How do I propagate Nasturtium Tropaeolum?
Nasturtium Tropaeolum is most commonly propagated by seed. Sow seeds directly into the garden in spring after the last frost or start them indoors 4-6 weeks prior. Soak the seeds in water overnight before planting to improve germination.
Paw Paw
What are the light requirements for Paw Paw?
Paw Paw trees require bright, indirect light to thrive indoors. Insufficient light can lead to leggy growth and reduced fruit production (if fruiting). A location near an east- or west-facing window is ideal. Avoid direct sunlight, especially during the hottest part of the day, as it can scorch the leaves. If natural light is limited, supplement with a grow light. Rotate the plant regularly to ensure even light exposure on all sides. Observe the plant’s growth habit to determine if it’s receiving adequate light. If the stems are stretching towards the light source, it indicates that more light is needed.
How do I care for Paw Paw?
To successfully grow Paw Paw indoors, provide bright, indirect light, ideally near an east- or west-facing window. Use a well-draining potting mix rich in organic matter. Water thoroughly when the top inch of soil feels dry, allowing excess water to drain away. Maintain moderate humidity levels, especially during winter months when indoor air tends to be drier. Fertilize sparingly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Repot young plants annually in spring, increasing the pot size gradually. Prune to maintain shape and remove any dead or damaged branches. Protect from drafts and sudden temperature changes. Monitor regularly for pests and diseases. Provide stable growing conditions, avoiding overwatering or underwatering.
How do I propagate Paw Paw?
Paw Paw can be propagated by stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from new growth in spring or early summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist. Cover with a plastic bag to maintain humidity. For air layering, make a small incision on a stem and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Once roots develop, cut the stem below the roots and plant it in a pot. Both methods require patience and consistent moisture.
