About Tina butterwort
Pinguicula 'Tina' · also called Tina butterwort, Tina Mexican butterwort · houseplant
Pinguicula 'Tina' (P. agnata × P. zecheri) is one of the most beginner-friendly Mexican butterwort hybrids, forming a flat rosette of lime-green glistening leaves that trap fungus gnats year-round. It blooms prolifically with pale lavender flowers and undergoes a compact succulent winter phase rather than true dormancy.
Preferred mix: Gritty mineral carnivorous plant mix
Watch for — Stunted growth and yellowing from tap water: Dissolved minerals in tap water accumulate in the root zone and cause nutrient toxicity (paradoxically). Always use mineral-free water. If leaves yellow and growth stalls, flush the pot repeatedly with distilled water and repot into fresh mix.
Why tina butterwort needs this mix
Tina butterwort is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Tina butterwort 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.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons tina butterwort 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 tina butterwort'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 tina butterwort.
pH — does it matter for tina butterwort?
Tina butterwort 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.
