About Mediterranean Everlasting

Helichrysum stoechas · also called Mediterranean Everlasting, Common Shrubby Everlasting · flowering

Helichrysum stoechas is a compact, aromatic, evergreen subshrub native to the Mediterranean basin, including south-west Europe and northern Morocco. It thrives in full sun and sharply drained, poor-to-moderately fertile neutral to alkaline soil, where it produces clusters of small, papery golden-yellow flowerheads through summer. The single most important care fact is that it will not tolerate waterlogged soil or prolonged winter wet, which causes root rot and crown collapse far more readily than cold does. Helichrysum is not listed by the ASPCA as toxic to cats or dogs; treat as mildly-toxic due to limited formal evaluation.

Mature size: 30–60 cm tall and 30–60 cm wide.

Watch for — Root rot: The most common cause of plant death. Caused by overwatering or poorly drained soil; stems blacken at the base and the plant wilts despite moist soil. Improve drainage and reduce watering immediately.

How to tell mediterranean everlasting needs repotting

Repotting on a calendar is less reliable than reading the plant. For mediterranean everlasting, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

What size pot to step mediterranean everlasting up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Mediterranean Everlasting stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot mediterranean everlasting

Spring or summer, while mediterranean everlasting is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting mediterranean everlasting

Repot dry. Do not water mediterranean everlasting for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty poor to moderately fertile, sharply drained, neutral to alkaline ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set mediterranean everlasting at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep mediterranean everlasting completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for mediterranean everlasting

Mediterranean Everlasting wants poor to moderately fertile, sharply drained, neutral to alkaline. Sandy or gritty soils work best; avoid clay or rich composts, which hold too much moisture and cause root rot. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.
