Pinguicula 'Johanna'
Mexican butterwort cultivar / Cultivated hybrid of Mexican species
A butterwort cultivar selected from a cross of Pinguicula agnata and Pinguicula debbertiana, described by Christian Weinberger in 2010. Its rounded leaves can blush orange-red in bright light, and its flowers are pale purple. Sticky summer leaves catch small insects; the winter rosette is smaller and more compact.
Supplied by the grower as Pinguicula 'Johanna'. The original collection photograph has a strong pink lighting cast, so natural leaf color may look different in daylight.

Instructions that travel with the plant.
- Give bright light near a window or under a grow light. Increase light gradually to encourage color while protecting the leaves from harsh afternoon sun and heat.
- Use a loose Mexican butterwort mix with mineral ingredients such as perlite, pumice, and sand, in a pot with drainage. Avoid ordinary fertilized potting soil.
- Water with distilled, rain, or reverse-osmosis water. Keep the mix lightly moist while the plant produces sticky carnivorous leaves, with good drainage around the crown.
- Keep frost-free, ideally around 55-85 F (13-29 C), and provide gentle air movement, especially in humid growing spaces.
- As smaller, tighter succulent leaves replace the sticky leaves, reduce watering and let the mix become drier between light waterings. Resume more regular moisture when carnivorous growth returns; follow the leaves rather than a fixed calendar.
