About Red Vygie
Lampranthus coccineus · also called Red Vygie, Scarlet Ice Plant · houseplant
Red Vygie is a striking South African succulent in the Aizoaceae family, producing vivid scarlet-red, daisy-like flowers in spring. Its silvery-green, cylindrical leaves form sprawling mats ideal for sunny containers and rockeries. One of the most brightly coloured Lampranthus species. Non-toxic and considered pet-safe.
Preferred mix: Fast-draining cactus or succulent compost with added grit
Watch for — Root and stem rot: Overwatering or waterlogged soil causes rapid rot. Use fast-draining compost and allow full soil drying between waterings.
Why red vygie needs this mix
Red Vygie is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Red Vygie 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 red vygie 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 red vygie'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 red vygie.
pH — does it matter for red vygie?
Red Vygie 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.
DIY mix vs a bagged one
A decent bagged houseplant compost works for red vygie 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
A pot with a drainage hole and a saucer you empty after watering is all red vygie needs — the free-draining mix does the rest.
Refresh red vygie's mix every 18-24 months; even good compost slumps and compacts, and fresh, airy mix is often the simplest fix for a tired plant. When the time comes, our repotting guide for red vygie covers the timing and technique step by step.
