Common name: Butterwort, Ping
Scientific name: Pinguicula
Common Info:
Butterworts grow all over the world and can even be found in Canada. They have low growing rosette shapes, many with wide leaves and all have beautiful flowers. The leaves produce a sticky mucus that attracts and captures small insects which are then digested on top of and re-absorbed by the leaves.
 
Care:

Most Pinguicula are fairly easy to grow in a humid environment. They will thrive in bright indirect light, direct sun need not be avoided as it will bring out the color in them. There are tropical, sub-tropical and temperate pings and their care requirements differ according to the climactic zone the plants are native to. Although the plants can tolerate temperatures from about 40 degrees F, it is best to keep temperatures between 55-80 degrees F. Potting in a 4-6 inch plastic pot should be adequate if the tray system for humidity is used as some of these plants can grow up to 6 inches across. The best soil mixes for them include 50/50 sand and peat moss or 2 parts peat moss and 1 part perlite. Keep the plant moist but not as wet as other CP's and do not leave sitting in water or allow to dry out. Pale, limp growth indicates more light is needed and a healthy plant will have a sparkle and color to it's leaves. Feeding is not usually needed as the plants capture small gnats and other insects. In a situation where the plants cannot catch insects, it is beneficial to sprinkle a few ant sized insects on a leaf a few times a year. Dead insects work well and are less likely to crawl off.

Pinguicula primuliflora

Pinguicula moranensis

A large hybrid of P. moranensis with very large deep pink flowers. I find it to be a fast grower with large leaves and easy to care for with it's habits being the same as P. moranensis. I particularly enjoy having the plant amongst my other carnivorous plants as it catches the fungus gnats that frequent the damp peaty soil mix. (note the black specks on the leaves)
Pinguicula primuliflora is a warm temperate butterwort from the southern United States and Florida. The plant usually grows to a three inch in diameter size and should be kept out of direct sunlight. In their native habitat they are found in wet areas of sphagnum and peat in shaded areas. They have beautiful flowers of violet pink and yellow. They have a slight dormancy period in the winter when growth slows but do not require temps lower than room temperature for that time.
Probably the most popular ping, P. moranensis is a tropical variety from Mexico. It does well on windowsills, in terrariums and outside in the summer. As winter approaches watch the plant to see if it's leaves begin changing shape. As it enters it's stage of dormancy the leaves will become non-carnivorous and take on a thicker succulent appearance. At this point let the soil dry a bit and water as you would a common house plant. In late spring it will start to grow the wider carnivorous leaves  and will require more frequent watering again.
