Nasturtium vs Princess Flower Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Nasturtium
Tropaeolum majus
Nasturtium (Tropaeolum majus) is an annual flowering plant known for its vibrant, edible flowers and peppery-flavored leaves. It features round, shield-shaped leaves and spurred flowers in shades of orange, yellow, and red. Typically grown outdoors in gardens and containers, it's valued for its ornamental appeal, culinary uses, and ability to attract pollinators. It's not ideally suited as a long-term indoor plant due to its high light requirements and sprawling growth habit.
Princess Flower
Tibouchina urvilleana
Tibouchina urvilleana, commonly known as Princess Flower, is a fast-growing evergreen shrub or small tree prized for its vibrant purple flowers. Native to Brazil, it typically grows outdoors in warm climates. It features velvety, dark green leaves and produces profuse blooms throughout the warmer months. While it can be grown in containers, it requires significant sunlight and humidity to thrive, making it challenging to maintain indoors long-term. People grow it for its showy flowers and tropical appearance.

❓ Frequently Asked Questions — Comparing These Plants
Nasturtium
What are the light requirements for Nasturtium?
Nasturtiums thrive best in full sun, requiring at least 6 hours of direct sunlight each day for abundant flowering. While they can tolerate partial shade, reduced sunlight can lead to fewer blooms and leggy growth. In hotter climates, providing some afternoon shade can prevent leaf scorch.
How do I care for Nasturtium?
Nasturtiums are relatively easy to care for, making them a great choice for beginner gardeners. They thrive in full sun to partial shade, requiring at least 6 hours of sunlight per day for optimal blooming. Water regularly, allowing the soil to dry slightly between waterings; avoid overwatering, which can lead to root rot.
How do I propagate Nasturtium?
Nasturtiums are easily propagated from seeds or stem cuttings. To propagate from seeds, sow seeds directly into the garden or containers in spring after the last frost. Alternatively, start seeds indoors 4-6 weeks before the last frost. Soak seeds in water overnight to improve germination.
Princess Flower
What are the light requirements for Princess Flower?
Princess Flower thrives in bright, indirect sunlight. Ideally, it needs at least 6 hours of sunlight per day to produce abundant blooms. A location near an east- or west-facing window is often suitable indoors. Avoid direct afternoon sun, which can scorch the leaves. If grown outdoors, provide partial shade during the hottest part of the day. Insufficient light can result in fewer blooms and leggy growth. Rotate the plant regularly to ensure even light exposure on all sides. During the winter months, when sunlight is less intense, consider supplementing with artificial grow lights.
How do I care for Princess Flower?
Princess Flower requires well-draining, acidic soil with a pH of 5.5 to 6.5. Water thoroughly when the top inch of soil feels dry, allowing excess water to drain. Fertilize every 2-4 weeks during the growing season (spring to fall) with a balanced fertilizer formulated for flowering plants. Prune regularly to maintain shape and encourage bushier growth and more blooms. Provide bright, indirect sunlight for at least 6 hours a day. Maintain a moderate humidity level, especially indoors. Protect from frost and freezing temperatures. Repot every 1-2 years as needed, using a slightly larger pot. Monitor for pests like aphids and spider mites, and treat promptly if detected. Ensure good air circulation to prevent fungal diseases.
How do I propagate Princess Flower?
Princess Flower can be propagated using stem cuttings. Take 4-6 inch cuttings from new growth in spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a well-draining potting mix. Keep the soil moist and provide bright, indirect light. Rooting typically occurs within 4-8 weeks. Division can be done when repotting mature plants, carefully separating the root ball. Keikis are not common on Princess Flower.
