Appearance
Helichrysum plants vary in size, from low-growing ground covers to tall shrubs. They have narrow, silver-gray leaves and produce clusters of small, yellow or white flowers that bloom in late summer. The flowers are papery and dry, but retain their bright color for a long time, hence the common name “everlasting flower.” Helichrysum flowers are often used in dried flower arrangements and wreaths.
Care Guide
Helichrysum plants are easy to care for and can thrive in a variety of growing conditions. Here are some care tips:
Water: Helichrysum plants prefer well-draining soil and do not like to be overwatered. Water deeply once a week, allowing the top inch of soil to dry out between waterings.
Fertilization: Helichrysum plants do not need much fertilizer. Feed once a month during the growing season with a balanced fertilizer.
Soil: Helichrysum plants prefer well-draining soil with a pH between 6.0 and 7.5. If planting in pots, use a cactus or succulent mix.
Sunlight: Helichrysum plants prefer full sun to partial shade. They can tolerate some shade, but will not bloom as much.
Hardiness Zones: Helichrysum plants are hardy in zones 8-10.
