About Stonecrop 'Dragon's Blood'
Phedimus spurius · also called Dragon's Blood Sedum, Two-Row Stonecrop · flowering
Phedimus spurius 'Dragon's Blood' (formerly Sedum spurium 'Schorbuser Blut') is a vigorous ground-covering stonecrop with semi-evergreen bronze-red tinted foliage that intensifies to vivid red in cold weather. Deep rose-pink flowers cover the mat in midsummer. Tough, drought-tolerant, and ideal for rock gardens, walls, and edging. Considered pet-safe based on ASPCA Sedum guidance.
Preferred mix: Sharply draining, gritty or sandy soil; poor to average fertility
Watch for — Root and crown rot: Caused by waterlogged or heavy, poorly drained soil; always plant in gritty, free-draining conditions.
Why stonecrop 'dragon's blood' needs this mix
Stonecrop 'Dragon's Blood' 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.
- Stonecrop 'Dragon's Blood' 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 stonecrop 'dragon's blood' 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 stonecrop 'dragon's blood'; 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 stonecrop 'dragon's blood' 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 is not a concern for stonecrop 'dragon's blood' — 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.
