Foxtail Lily vs Willow Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Foxtail Lily
Eremurus spp.
Foxtail Lilies are striking perennial plants known for their tall, dense flower spikes that can reach impressive heights. They emerge from a central rosette of basal leaves and produce a towering inflorescence covered in hundreds of small, star-shaped flowers. These plants are primarily outdoor specimens, thriving in sunny gardens. People grow them for their dramatic vertical presence and the vibrant colors they bring to the landscape. They are not naturally suited for indoor environments due to their high light requirements and dormancy needs.
Willow
Salix spp.
Willows are deciduous trees or shrubs characterized by their slender branches and lance-shaped leaves. They are known for their rapid growth and adaptability to moist environments. Many species, such as the Weeping Willow (Salix babylonica), are cultivated for their graceful, drooping branches, making them popular ornamental trees in parks and gardens. Willows are primarily outdoor plants and are rarely, if ever, suitable for indoor cultivation due to their size and environmental needs.

💡 Pro Tips For Comparing These Plants
Foxtail Lily Care Tips
Foxtail Lilies are not suitable for indoor growing due to their high light requirements and dormancy needs. They require full sun, well-draining soil, and a period of winter dormancy. Indoor attempts will likely result in weak growth and failure to flower.
- Plant the crown with the roots spread out like an octopus.
- Ensure excellent drainage to prevent root rot.
- Provide support for tall flower spikes to prevent them from bending or breaking.
- Protect from slugs and snails, especially when young.
- Allow foliage to die back naturally in the fall to replenish the bulb's energy reserves.
Willow Care Tips
Willows are primarily outdoor trees and are not suitable for indoor cultivation. Their large size, high light requirements, and need for consistent moisture make them challenging to grow indoors. Attempting to grow a willow indoors will likely result in a stressed and unhealthy plant.
- Plant in a location with ample space for growth.
- Water deeply and regularly, especially during dry periods.
- Prune annually to maintain shape and remove dead or diseased branches.
- Monitor for pests and diseases and treat promptly.
- Mulch around the base of the tree to retain moisture and suppress weeds.

❓ Frequently Asked Questions — Comparing These Plants
Foxtail Lily
What are the light requirements for Foxtail Lily?
Foxtail Lilies require at least six to eight hours of direct sunlight per day to thrive and produce their impressive flower spikes. A south-facing location is ideal, ensuring they receive ample sunlight throughout the growing season. Insufficient sunlight can result in weak stems, reduced flowering, and overall poor plant health.
How do I care for Foxtail Lily?
Foxtail Lilies require well-drained soil and a sunny location to thrive. Plant the rhizomes (thickened roots) in the fall, burying them about 4-6 inches deep, with the crown facing upwards. Ensure the soil is amended with organic matter to improve drainage. Water thoroughly after planting and then sparingly until spring growth begins.
How do I propagate Foxtail Lily?
Foxtail Lilies are typically propagated by division of the rhizomes in the fall. Carefully dig up the plant and separate the rhizomes, ensuring each division has at least one growth point. Replant the divisions in well-drained soil.
Willow
What are the light requirements for Willow?
Willows grown indoors need bright, indirect light to flourish. A location near an east- or west-facing window is ideal, providing several hours of gentle sunlight each day. Avoid placing your Willow in direct, intense sunlight, especially during the hottest part of the day, as this can cause leaf scorch.
How do I care for Willow?
Indoor Willow trees require bright, indirect light to thrive; avoid direct sunlight, which can scorch the leaves. Water thoroughly when the top inch of soil feels dry to the touch, ensuring proper drainage to prevent root rot. Maintain a consistent level of moisture, but do not allow the plant to sit in standing water.
How do I propagate Willow?
Willows are relatively easy to propagate using stem cuttings or air layering. For stem cuttings, take a 6-8 inch cutting from a healthy branch. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in moist potting mix and cover with a plastic bag to create a humid environment. Keep the soil moist and provide bright, indirect light. Roots should develop within a few weeks.
