About Pilea microphylla 'Variegata'
Pilea microphylla 'Variegata' · also called variegated artillery plant, variegated rockweed · houseplant
Pilea microphylla 'Variegata' is the variegated artillery plant, a fine-textured bushy pilea with tiny ferny leaves splashed cream, pink and green. Named for the way it flicks pollen, it enjoys bright indirect light, warmth and lightly moist, free-draining soil. Compact and easy to grow. ASPCA-listed as non-toxic to cats and dogs.
Preferred mix: Light, free-draining houseplant mix
Watch for — Brittle stem breakage: The wiry stems snap easily and rot if waterlogged. Handle gently and use a free-draining mix.
Why pilea microphylla 'variegata' needs this mix
Pilea microphylla 'Variegata' is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Pilea microphylla 'Variegata' is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.
For the full picture on what makes up a good mix, see our guide to the main types of soil and potting media — it explains why each ingredient above behaves the way it does.
What goes wrong with the wrong mix
The wrong soil is one of the most common reasons pilea microphylla 'variegata' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain garden soil or a cheap, claggy compost compacts in the pot and slowly suffocates pilea microphylla 'variegata''s roots.
- A pure peat mix that dries to a hard, water-repelling block is hard to re-wet and stresses the plant.
- No drainage hole turns even a good mix into a stagnant, root-rotting sump.
Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for pilea microphylla 'variegata'.
pH — does it matter for pilea microphylla 'variegata'?
Pilea microphylla 'Variegata' is not fussy about pH — a slightly acidic to neutral mix (around pH 6.0-7.0), which a standard peat-free compost provides, is perfectly fine. No testing needed.
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.

A decent bagged houseplant compost works for pilea microphylla 'variegata' as long as you mix in perlite for air. The simple DIY ratio above is cheap and more reliable than a budget bag alone.
Drainage and the pot
