Nasturtium Tropaeolum vs Pineapple Guava 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.
Pineapple Guava
Acca sellowiana (syn. Feijoa sellowiana)
Pineapple Guava is an evergreen shrub or small tree, typically grown outdoors for its ornamental value and edible fruit. It features attractive gray-green foliage, showy red and white flowers with edible petals, and egg-shaped, green fruit with a sweet, aromatic flavor reminiscent of pineapple and guava. While it can be grown in containers, it thrives best outdoors where it can reach its full potential. People grow it for its unique fruit, attractive appearance, and relatively low maintenance once established.

💡 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.
Pineapple Guava Care Tips
Pineapple Guava is best suited for outdoor growing. Indoor cultivation is challenging due to high light requirements and the need for pollination to produce fruit. It requires well-draining soil, regular watering, and fertilization. Expect reduced growth and potentially no fruit production indoors.
- Provide well-draining soil to prevent root rot.
- Water deeply but infrequently, allowing the soil to dry out slightly between waterings.
- Fertilize regularly during the growing season with a balanced fertilizer.
- Prune annually to maintain shape and encourage fruit production.
- Protect from frost in colder climates.

❓ 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.
Pineapple Guava
What are the light requirements for Pineapple Guava?
Pineapple Guava thrives in bright, indirect light indoors. A south-facing window is ideal, but if the light is too intense, filter it with a sheer curtain. Insufficient light can lead to leggy growth, reduced flowering, and less fruit production. If natural light is limited, supplement with grow lights.
How do I care for Pineapple Guava?
To successfully grow Pineapple Guava indoors, provide bright, indirect light, ideally near a south-facing window. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain moderate humidity levels by misting regularly or using a humidifier. Use a well-draining potting mix formulated for fruit trees. Fertilize monthly during the growing season (spring and summer) with a balanced fertilizer.
How do I propagate Pineapple Guava?
Pineapple Guava can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch semi-hardwood cutting in late 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 and humid. Roots should develop in 6-8 weeks.
