About Kiwi Aeonium
Aeonium haworthii 'Kiwi' · also called Tricolor Aeonium, Pinwheel Aeonium · houseplant
Aeonium 'Kiwi' is a freely branching shrubby succulent prized for its tricolour rosettes: pale yellow-green centres flushing rose-red at the leaf margins in bright light. It clusters into a rounded mound of many small pinwheel rosettes. Like all aeoniums it grows in cool months and rests in summer heat, needing bright light and gritty, fast-draining soil.
Preferred mix: Gritty cactus and succulent mix
Watch for — Etiolation and stretching: Stems lengthen and rosettes loosen in dim conditions. Move to brighter light; pinch or behead leggy stems and root the tips to restore a compact form.
Why kiwi aeonium needs this mix
Kiwi Aeonium stores water in its leaves and stems, so it wants a free-draining, gritty mix that dries out fully between waterings — not a moisture-holding one.
- Kiwi Aeonium carries its own water supply in its thick tissue, so the soil's job is to drain fast and then get out of the way.
- Its roots are adapted to short wet spells followed by long dry ones — a mix that stays damp removes the dry phase they depend on.
- A gritty mix also keeps the plant compact and well-coloured rather than soft, leggy and prone to collapse.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons kiwi aeonium struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Standard potting compost on its own stays wet far too long for kiwi aeonium; the lower leaves and stem base go soft and translucent first.
- Big plastic pots full of dense mix hold a wet core long after the surface looks dry — that hidden wet zone is where rot starts.
- Anything sold as "moisture control" is the opposite of what this plant wants.
Treating kiwi aeonium like a leafy houseplant and using plain compost. It needs at least half its volume as grit, perlite or pumice to survive long term.
pH — does it matter for kiwi aeonium?
pH is not a concern for kiwi aeonium — anything from mildly acidic to neutral (6.0-7.0) works. Get the drainage right and pH looks after itself.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A good bagged "cactus and succulent" mix works for kiwi aeonium if you add roughly 30-50% extra perlite or grit. Mixing your own from the ratio above gives you full control of how fast it dries.
Drainage and the pot
Use a pot with a drainage hole and empty the saucer within minutes of watering. Terracotta is more forgiving than glazed or plastic because it dries the rootball faster.
This mix decomposes slowly, so kiwi aeonium only needs repotting every 2-3 years — mainly to refresh the grit and check the roots are firm and pale. When the time comes, our repotting guide for kiwi aeonium covers the timing and technique step by step.
