Butterfly Weed vs Franklin Tree Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Butterfly Weed
Asclepias tuberosa
Butterfly Weed is a herbaceous perennial native to North America, known for its vibrant orange (sometimes yellow or red) flowers. It typically grows to a height of 1-3 feet with an upright, bushy habit. Unlike other milkweeds, it does not have milky sap. It's primarily an outdoor plant, valued for attracting butterflies, especially Monarchs, and other pollinators to gardens. It is grown for its bright blooms and its role as a host plant for Monarch butterfly larvae.
Franklin Tree
Franklinia alatamaha
The Franklin Tree is a deciduous tree or large shrub known for its beautiful camellia-like, fragrant white flowers that bloom in late summer to early fall. It has attractive, glossy green leaves that turn vibrant shades of red and orange in the fall. Sadly, it is extinct in the wild, making it a rare and highly prized ornamental tree. It typically grows to a height of 10-30 feet. People grow it for its stunning floral display, fall color, and historical significance.

💡 Pro Tips For Comparing These Plants
Butterfly Weed Care Tips
Butterfly Weed is primarily an outdoor plant that thrives in full sun and well-drained soil. It is very difficult to grow indoors due to its high light requirements and dormancy needs. Attempting to grow it indoors will likely result in a weak, leggy plant that does not flower well, if at all.
- Ensure well-draining soil to prevent root rot.
- Provide full sun for optimal flowering.
- Deadhead spent flowers to encourage more blooms.
- Monitor for aphids and other pests.
- Avoid over-fertilizing, as this can reduce flowering.
Franklin Tree Care Tips
The Franklin Tree is primarily an outdoor tree and is not suitable for indoor growing. It requires specific soil conditions, consistent moisture, and protection from extreme temperatures. Maintaining proper acidity and drainage is crucial for its survival. Indoor growing is not recommended due to its size and environmental needs.
- Ensure the soil is consistently moist but not waterlogged.
- Apply an acid-forming fertilizer in early spring.
- Mulch around the base of the tree to retain moisture and suppress weeds.
- Protect from harsh winds and extreme cold in winter.
- Monitor for pests and diseases and treat promptly.

❓ Frequently Asked Questions — Comparing These Plants
Butterfly Weed
What are the light requirements for Butterfly Weed?
Butterfly Weed requires at least six hours of direct sunlight daily to thrive and produce abundant blooms. A sunny location is crucial for its growth and flowering potential. Insufficient light can result in leggy growth, reduced blooming, and weaker stems. When planting, choose a spot that receives full sun throughout the day. If growing in containers, rotate the plant regularly to ensure even light exposure on all sides. In areas with intense summer heat, some afternoon shade may be beneficial to prevent scorching. Observe your plant and adjust its location if needed to ensure it receives adequate sunlight.
How do I care for Butterfly Weed?
Butterfly Weed thrives in full sun and well-drained soil. Water deeply but infrequently, allowing the soil to dry out between waterings. Fertilize sparingly, if at all, as excessive fertilization can reduce flowering. Deadhead spent flowers to encourage continued blooming. Prune back stems in late fall or early spring to promote bushier growth. Provide support if needed, especially in windy areas. Monitor for pests such as aphids and treat accordingly. Ensure good air circulation to prevent fungal diseases. Butterfly Weed is relatively drought-tolerant once established, but regular watering is important during the first year. Avoid overwatering, which can lead to root rot.
How do I propagate Butterfly Weed?
Butterfly Weed can be propagated by seed, division, or root cuttings. For seed propagation, sow seeds in the fall or stratify them in the refrigerator for 30-60 days before planting in the spring. Division is best done in early spring or late fall. Carefully dig up the plant and divide the root ball into smaller sections, ensuring each section has healthy roots and stems. Replant the divisions in well-drained soil. Root cuttings can be taken in late winter or early spring. Dig up a portion of the root system and cut it into 2-3 inch sections. Plant the cuttings horizontally in a well-draining potting mix and keep them moist until new growth appears.
Franklin Tree
What are the light requirements for Franklin Tree?
Franklin Trees thrive in bright, indirect light. Avoid direct sunlight, especially during the hottest parts of the day, as it can scorch the leaves. An east-facing window is often ideal, providing gentle morning sun. A south- or west-facing window can also work, but be sure to filter the light with a sheer curtain to prevent leaf burn. Insufficient light can lead to leggy growth and reduced flowering.
How do I care for Franklin Tree?
To successfully grow a Franklin Tree indoors, begin with a well-draining potting mix in a pot at least 12 inches in diameter. Place it in a location with bright, indirect light. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to avoid root rot. Maintain moderate humidity levels, ideally around 50-60%, using a humidifier if necessary.
How do I propagate Franklin Tree?
Franklin Trees can be propagated through stem cuttings and air layering, though both methods can be challenging. For stem cuttings, take a 4-6 inch cutting from new growth 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 consistently moist and humid. Place a plastic bag over the cutting to retain humidity. Rooting can take several weeks to months.
