Pinguicula Poldinii
One of the most recent discoveries has been Pinguicula poldinii, a wonderful new species from the prealps, in Friuli Venezia Giulia (Italy). It grows at an altitude of 450-550 meters. In Spring, the cycle begins by the opening of the Winter buds, hibernacula, and the production of the first carnivorous leaves. The first leaves are followed by the flowers in Summer. Purple-blue flowers with a white throat. New carnivorous leaves are produced during all the season. Near Autumn, or earlier, if your conditions are not optimal, the next hibernacula is revealed in the centre of the rosette. Then leaf production stops and the old leaves decay slowly. The plant, reduced now to a small hibernacula, is ready for Winter and for the next cycle. The leaves of Pinguicula poldinii are oval, medium green, in basal rosettes and are covered with sticky, mucilage-secreting and digestive hairs. The margins roll inward in response to contact of the hairs by potential prey organisms. Nitrogenous and other nutrients released by the digested prey supplement the plant's requirements. These modifications help such plant species compete in nutrient-deficient habitats. Pinguicula Poldinii is from the temperate climates and require a dormancy period. During dormancy the plant die back to a resting bud known as a hibernacula. Temperate Butterworts not only reproduce by seed, but also by gemmae. These gemmae, brood bodies, form around the base of the hibernacula. They look like miniature resting buds. They break of from the hibernacula very easily and are scattered around, assisting on the further propagation of the species. Hardiness zone 8 (-10C/15F) in Winter. Pinguicula poldinii is native to areas with cold, distinct Winters, the plant needs cold Winter temperatures to survive. Habitats may vary from semi-shady to full sun exposition. Optimal Summer growing conditions are good air humidity, cool temperature and UV lights. If the Summer growing conditions are not optimal, the plants will form very weak hibernacula which easily rot. During growth period, procure a day temperatures of about 25øC and night temperatures around 20øC. During resting period days and nights should be over freezing point. Keep above 7øC in Winter. Best grown outdoors as a container or potted plant. Because of their specific soil requirement, avoid planting them in the ground. Excellent for the deck or patio. This Butterwort can be grown in a mixture of one part peat, two parts perlite, and one part vermiculite. Use rain water poured on the top of the pot taking care not to wet the rosette. When this Pinguicula begins to produce its non-carnivorous leaves, from October to April, it is important to restrict the water somewhat, but never allow the plants to dry completely. Inversely, when the plant begins to produce in early Spring its carnivorous leaves, you have to progressively start watering again the pot. Let the media drying slightly between two watering.

Germination Those seeds require 2-3 months cold stratification before sowing, directly on the surface of your moist but not soaked soil mix. Once it's time to take the seeds out of cold stratification, cover the top of the pot with clear plastic so the humidity will remain high, place them in an area with real nice strong light and keep the temperature around 20øC/68øF, 24øC/75øF.

When you see some tiny plants starting to sprout, slowly open the top of the pot, a little each day, so that the new seedlings don't go into shock from the humidity being lowered too quickly. After cold stratification, germination can take several months. It can be more depending on their degree of unbroken dormancy, don't give up.
Scarification / Stratification It creates a cold and moist environment for the seeds. This will break their dormancy. Place the seeds on top of a prepared soil mix. The pot is then placed into a ziplock bag with approximately an inch of water on the bottom of the bag. Close the bag shut and place it into the salad crisper compartment of your refrigerator. Make sure to check the seeds often. If fungus or mold appears treat it with a fungicide.
