A: These are all plants of cold climates that survive the cold winters by making tight little buds called hibernacula. These tight buds are usually loosely attached to the ground, and detach readily. Once detached, they float with the spring melt waters, dispersing plant propagules. A smaller number of species have hibernacula that are tightly attached to the soil surface.

Some of these species have subspecies described for them. These are mentioned below, and also on the big Pinguicula check list that is coming up in a few pages.

A few records of likely natural hybrids have been observed for these plants. These include Pinguicula grandiflora × vulgaris, Most of the Pinguicula species on this page are somewhat challenging to grow, as they have winter dormancy requirements which must be respected. Furthermore, their flowers are for the most part relatively small and not amazingly showy. Still, I think their flowers have a healthy dose of beauty dust, and I like these plants a great deal.

I have discussed Pinguicula macroceras, Pinguicula villosa, and Pinguicula vulgaris on the previous web page, but comments on some of the other species follow.

Pinguicula apuana--very similar to P. vulgaris, but with a larger corolla with longer spur, and with a two-parted white palate patch. This seems to me a fairly unimpressive set of arguments, but I bow to the expertise of the secondary author (Jost Casper) of the describing paper.

Pinguicula balcanica--Two additional subspecies have been described by Casper for this plant: P. b. subsp. pontica and P. b. subsp. tenuilaciniata.

Pinguicula grandiflora--This species is one of the easier to maintain in cultivation, and has large, colorful flowers. Casper described an additional subspecies (P. g. subsp. rosea) which has light pink flowers and some other minor character differences.

Pinguicula longifolia--This is a plant which is a source of great arguments. A common perspective is that it should be considered to have four subspecies: P. l. subsp. longifolia (Spain, France), P. l. subsp. caussensis (France), P. l. subsp. dertosensis (Spain), and P. l. subsp. reichenbachiana (France, Italy). I have adopted this approach. On the other hand, some prefer treating each at species rank. (Note, however, there is no legitimate name available for treating P. l. subsp. caussensis at a species rank.)

Pinguicula ramosa--This small Japanese species is remarkable in having forked inflorescences. This occasionally occurs in other species, but never regularly.

Pinguicula vallisneriifolia--This plant has long, almost stringlike leaves. The species name notes that the plant has leaves (foliage) like those of Vallisneria (eelgrass).
