New England Aster vs Princess Tree Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
New England Aster
Symphyotrichum novae-angliae
The New England Aster is a robust, clump-forming perennial wildflower, typically reaching heights of 3-7 feet. It's characterized by its lance-shaped, clasping leaves and vibrant daisy-like flowers that bloom in late summer and fall. The flowers are typically purple or violet, with a yellow center disk. This plant is primarily an outdoor species, valued for its late-season color and its ability to attract pollinators like butterflies and bees. It's rarely grown indoors due to its high light requirements and size.
Princess Tree
Paulownia tomentosa
Paulownia tomentosa, the Princess Tree, is a deciduous tree known for its rapid growth and large, heart-shaped leaves. It can reach heights of 30-60 feet. In spring, it produces fragrant, pale purple flowers in panicles before the leaves emerge. These are followed by persistent seed capsules. While admired for its ornamental value, it's considered invasive in many regions due to its prolific seed production and ability to resprout from roots. It is primarily an outdoor tree and not suitable for indoor cultivation.

❓ Frequently Asked Questions — Comparing These Plants
New England Aster
What are the light requirements for New England Aster?
New England Aster demands ample sunlight to produce its profuse blooms. Ideally, provide at least six hours of direct sunlight each day. A south-facing location is generally best, although east- or west-facing exposures can also work if they receive sufficient sunlight. Insufficient light can result in leggy growth, reduced flowering, and increased susceptibility to diseases. If growing indoors, supplement natural light with grow lights, especially during the shorter days of fall and winter. Rotate the plant regularly to ensure even light exposure. If the leaves start to turn pale or yellow, it may indicate that the plant is receiving too little light.
How do I care for New England Aster?
New England Aster thrives in full sun, requiring at least six hours of direct sunlight daily. Water regularly, especially during dry periods, ensuring the soil remains consistently moist but not waterlogged. Fertilize in early spring with a balanced fertilizer to promote healthy growth and abundant blooms. Pinch back stems in late spring or early summer to encourage bushier growth and more flowers. Deadhead spent blooms to prolong the flowering season. Divide established clumps every few years to prevent overcrowding and maintain vigor. Provide support, such as staking, if the plants become too tall or leggy. Monitor for pests and diseases, and treat promptly if necessary. Ensure good air circulation to prevent fungal diseases. Mulch around the base of the plant to retain moisture and suppress weeds.
How do I propagate New England Aster?
New England Asters can be easily propagated through division, stem cuttings, or seeds. For division, carefully dig up an established clump in early spring or fall and separate it into smaller sections, each with healthy roots and shoots. Replant the divisions in well-prepared soil. For stem cuttings, take 4-6 inch cuttings from new growth in spring or early summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in moist potting mix and keep them humid until roots develop. Seeds can be sown in early spring indoors or directly in the garden after the last frost. Ensure proper spacing for optimal growth.
Princess Tree
What are the light requirements for Princess Tree?
Princess Tree thrives in bright, indirect light. Insufficient light can lead to leggy growth and reduced leaf size. Place your Princess Tree near a sunny window, ideally facing east or west. If you only have a south-facing window, filter the light with a sheer curtain to prevent scorching. Rotate the plant regularly to ensure even light exposure on all sides. If natural light is limited, consider supplementing with artificial grow lights to provide the necessary light intensity. Pale leaves or slow growth can indicate insufficient light.
How do I care for Princess Tree?
To successfully grow Princess Tree indoors, provide it with bright, indirect light; direct sunlight can scorch the leaves. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain moderate humidity levels, especially during the winter months when indoor air tends to be drier. Fertilize regularly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Repot the plant every 1-2 years, or when it becomes root-bound, using a well-draining potting mix. Prune as needed to maintain shape and remove any dead or damaged leaves. Monitor for pests such as spider mites and aphids, and treat promptly with insecticidal soap or neem oil. Maintain stable temperatures, avoiding drastic fluctuations.
