Compare these two plants side by side — care needs, key differences, and which is right for your home.
Helichrysum
Helichrysum petiolare
Helichrysum petiolare, commonly known as the Licorice Plant, is a tender perennial often grown as an annual. It features soft, rounded, silvery-gray leaves that are slightly fuzzy to the touch. The plant has a trailing or mounding growth habit, making it suitable for hanging baskets, containers, and as a ground cover in warmer climates. While it can be grown indoors, it thrives outdoors in full sun. People grow it for its attractive foliage, which adds a textural element to gardens and containers. It is not typically grown for its flowers, which are small and insignificant.

❓ Frequently Asked Questions — Comparing These Plants
Helichrysum
What are the light requirements for Helichrysum?
Helichrysum requires at least 6-8 hours of direct sunlight per day to thrive. Insufficient light can result in leggy growth, reduced flowering, and pale foliage. When grown indoors, place Helichrysum near a south-facing window where it can receive ample sunlight. If natural light is limited, supplement with grow lights to ensure adequate illumination.
How do I care for Helichrysum?
Helichrysum thrives in well-draining soil and requires full sun exposure for optimal growth and blooming. Water thoroughly when the top inch of soil feels dry, allowing excess water to drain away. Avoid overwatering, which can lead to root rot. Fertilize monthly during the growing season (spring and summer) with a balanced fertilizer to promote healthy growth and abundant blooms.
How do I propagate Helichrysum?
Helichrysum can be easily propagated through stem cuttings. Take 4-6 inch cuttings from healthy stems, removing the lower leaves. Dip the cut end in rooting hormone and plant in well-draining potting mix. Keep the soil consistently moist and provide bright, indirect light. Roots should develop within 2-4 weeks.
String of Pearls
What are the light requirements for String of Pearls?
String of Pearls thrives in bright, indirect light. An east-facing window is 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 sunburn. Insufficient light can lead to leggy growth, where the stems become stretched and the pearls are spaced far apart. Rotate the plant regularly to ensure even light exposure on all sides. If you notice the pearls becoming pale or translucent, it may be a sign of too much direct sunlight. If the pearls are shriveled, it might indicate not enough light combined with underwatering. Supplemental grow lights can be beneficial during the darker winter months.
How do I care for String of Pearls?
String of Pearls requires bright, indirect light; direct sunlight can scorch the delicate leaves. Water sparingly, allowing the soil to dry out completely between waterings, typically every 2-3 weeks. Overwatering is a common cause of root rot. Use well-draining soil, such as a cactus or succulent mix. Maintain average room temperatures (65-75°F or 18-24°C). Avoid temperatures below 50°F (10°C). String of Pearls prefers low to moderate humidity. Fertilize sparingly, only during the growing season (spring and summer), with a diluted balanced fertilizer. Prune any leggy or dead stems to encourage bushier growth. These plants thrive in hanging baskets or pots where their cascading vines can be displayed. Provide support structures such as small trellises or moss poles if you want to encourage upward growth. Repot only when necessary, usually every 1-2 years.
How do I propagate String of Pearls?
String of Pearls is easily propagated through stem cuttings or layering. For stem cuttings, take a 4-6 inch cutting and allow the cut end to callous over for a few days. Place the cutting on top of well-draining soil, gently pressing some of the pearls into the soil. Water sparingly, allowing the soil to dry out between waterings. Roots will typically develop within a few weeks. For layering, lay a strand of pearls directly on top of the soil in a new pot, pinning it down with small wire or clips. Water sparingly and allow the roots to develop before separating the new plant from the parent plant. These methods are great for filling out sparse areas or creating new plants.
