About Transylvanian Hepatica
Hepatica transsilvanica · also called Transylvanian Hepatica, Romanian Hepatica · flowering
Transylvanian Hepatica is a vigorous species native to the Carpathian mountains of Romania, producing large, intensely blue or pale blue flowers in early spring. It is more robust than H. nobilis, forming broader clumps faster, and is valued for its six-lobed leaves and superior garden performance. Fully cold-hardy and deer-resistant.
Preferred mix: Humus-rich, free-draining, slightly alkaline to neutral loam
Watch for — Crown rot in wet winters: Persistent winter wet causes rot where drainage is poor. Raise planting on a slight ridge or incorporate sharp grit generously to improve drainage.
Why transylvanian hepatica needs this mix
Transylvanian Hepatica is a Mediterranean dry-hillside plant — it wants a lean, sharply drained, slightly alkaline mix, and rots fast in rich, water-holding soil.
- Transylvanian Hepatica evolved on stony, sun-baked slopes — its roots expect to dry out hard and quickly between rains, so the mix must drain almost as fast as you pour.
- A lean, low-nutrient mix keeps growth firm and aromatic; a rich one gives soft, sappy, flavourless growth that flops and rots.
- It tolerates and often prefers a slightly alkaline soil, the opposite of most houseplants.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons transylvanian hepatica struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Rich, moisture-holding compost is the classic killer of transylvanian hepatica — especially over a cold, wet winter, when the base of the plant simply rots.
- A peaty, acidic potting mix is doubly wrong: too wet and the wrong pH direction.
- No grit means the rootball stays damp for days, which a dry-climate root system never copes with.
Growing transylvanian hepatica in ordinary rich, moisture-retentive compost. Lean it out with at least a third grit, and never let it sit wet over winter.
pH — does it matter for transylvanian hepatica?
Transylvanian Hepatica likes neutral to slightly alkaline soil, roughly pH 6.5-7.5. If your soil or compost is acidic, a little garden lime or extra grit nudges it the right way — the one common plant where you may add lime.
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
Bagged "herb" or "Mediterranean" mixes are usually fine for transylvanian hepatica, but most standard composts need cutting hard with grit. The DIY ratio above is cheap and exactly right.
Drainage and the pot
Sharp drainage is everything: a terracotta pot with a big hole, gritty mix and never a saucer left full. Raised beds suit these herbs outdoors for the same reason.
A gritty mix barely breaks down, so transylvanian hepatica needs little repotting — refresh the top layer and the grit every couple of years rather than potting on aggressively. When the time comes, our repotting guide for transylvanian hepatica covers the timing and technique step by step.

2 parts standard peat-free compost or loam : 1 part coarse horticultural grit : 1 part perlite or coarse sand. Transylvanian Hepatica evolved on stony, sun-baked slopes — its roots expect to dry out hard and quickly between rains, so the mix must drain almost as fast as you pour.
Can I use normal potting soil for transylvanian hepatica?
