Fan Flower vs Milfoil Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Fan Flower
Scaevola aemula
Scaevola aemula, commonly known as Fan Flower, is a tender perennial often grown as an annual. It features a distinctive fan-shaped flower arrangement, with blooms typically in shades of blue, purple, pink, or white. The plant has a mounding or trailing habit, reaching about 12-18 inches in height and spreading up to 24 inches. It is primarily an outdoor plant, prized for its continuous flowering throughout the warm season. People grow it for its vibrant colors, unique flower shape, and heat tolerance in garden beds, hanging baskets, and containers.
Milfoil
Achillea millefolium
Achillea millefolium, commonly known as yarrow, is a herbaceous perennial plant characterized by its feathery, finely divided leaves and clusters of small, daisy-like flowers. It typically grows to a height of 0.3 to 1 meter. The flowers are usually white, but can also be pink, red, or yellow in cultivated varieties. Yarrow is primarily an outdoor plant, thriving in sunny locations. It is grown for its ornamental value, medicinal properties (traditionally used for wound healing and anti-inflammatory purposes), and its ability to attract beneficial insects to the garden. It is not typically grown indoors due to its high light requirements and spreading growth habit.

💡 Pro Tips For Comparing These Plants
Fan Flower Care Tips
Fan Flower is primarily an outdoor plant and requires full sun to thrive. It can be challenging to maintain indoors due to its high light requirements. Providing adequate light, proper watering, and well-draining soil are crucial for its survival indoors. Expect reduced flowering and potentially leggy growth indoors.
- Provide well-draining soil to prevent root rot.
- Water deeply but infrequently, allowing the soil to dry slightly between waterings.
- Fertilize regularly during the growing season to promote continuous blooming.
- Pinch back stems to encourage bushier growth.
- Protect from frost if overwintering.
Milfoil Care Tips
Yarrow is primarily an outdoor plant that requires full sun and well-draining soil. It is relatively low-maintenance once established but is not suited for indoor growing due to its high light demands. Indoor cultivation is challenging and rarely successful.
- Provide full sun for optimal growth and flowering.
- Ensure well-draining soil to prevent root rot.
- Deadhead spent flowers regularly to encourage more blooms.
- Divide plants every few years to prevent overcrowding.
- Avoid over-fertilizing, as this can lead to leggy growth.

❓ Frequently Asked Questions — Comparing These Plants
Fan Flower
What are the light requirements for Fan Flower?
Fan Flower requires at least 6-8 hours of direct sunlight per day to thrive and produce abundant blooms. Insufficient light can lead to leggy growth and reduced flowering. When growing indoors, place Fan Flower near a south-facing window where it can receive ample sunlight. If natural light is limited, supplement with grow lights. Rotate the plant regularly to ensure even light exposure on all sides. In hot climates, provide some afternoon shade to prevent scorching. Monitor the plant for signs of light stress, such as pale or yellowing leaves, and adjust its location accordingly. Optimal light exposure is crucial for healthy growth and prolific flowering.
How do I care for Fan Flower?
Fan Flower thrives in well-draining soil and requires full sun for optimal blooming. Water regularly, allowing the top inch of soil to dry out between waterings. Fertilize every 2-3 weeks during the growing season with a balanced liquid fertilizer to promote abundant flowering. Deadhead spent blooms to encourage continuous blooming. Prune lightly to maintain shape and encourage bushier growth. Provide adequate air circulation to prevent fungal diseases. Protect from frost, as Fan Flower is not frost-hardy. In cooler climates, grow in containers that can be moved indoors during winter. Monitor for pests such as aphids and spider mites, and treat promptly if infestation occurs. Ensure proper drainage to prevent root rot.
How do I propagate Fan Flower?
Fan Flower can be propagated through stem cuttings or division.
Milfoil
What are the light requirements for Milfoil?
Milfoil requires moderate to high levels of light to thrive. Insufficient light will result in leggy growth and poor coloration. In aquariums, provide at least 2-3 watts per gallon of water using full-spectrum fluorescent or LED lighting. For outdoor ponds, position Milfoil in an area that receives at least 6 hours of direct sunlight per day. If the water is shaded, supplemental lighting may be necessary. Observe the plant’s growth; if the stems are elongated and the leaves are sparse, increase the light intensity or duration. Be mindful of algae growth, as high light levels can promote algae blooms. Balance the light intensity with nutrient levels and CO2 availability to prevent algae problems.
How do I care for Milfoil?
Milfoil thrives in aquatic or semi-aquatic environments. For submerged growth, maintain water temperatures between 60-80°F (15-27°C). Provide moderate to high lighting to encourage healthy growth; 6-8 hours of light per day is ideal. Ensure good water circulation and filtration to prevent algae buildup. For semi-aquatic growth, plant in consistently moist soil or substrate. Fertilize regularly with a liquid aquatic fertilizer, following the product instructions, to provide essential nutrients. Trim regularly to maintain desired shape and prevent overcrowding. Monitor water parameters, including pH (6.0-7.5) and nutrient levels, to optimize growth. Perform partial water changes regularly to maintain water quality. Remove any dead or decaying foliage promptly to prevent water contamination. Choose a location with minimal disturbance to allow the plant to establish itself.
How do I propagate Milfoil?
Milfoil is easily propagated through cuttings and division. For cuttings, select a healthy stem segment approximately 4-6 inches long. Remove the lower leaves and place the cutting in a glass of water or directly into the substrate. Ensure the cutting receives adequate light and warmth. Roots should develop within a few weeks. Once roots are established, transplant the cutting to its permanent location. For division, gently separate a mature plant into smaller sections, ensuring each section has roots and stems. Replant the divisions in separate locations. Both methods are highly successful, allowing you to quickly expand your Milfoil population. Regular trimming encourages branching and further propagation opportunities.
