Utricularia sp. (Bladderwort) is a small shrub reaching 2-5 feet in height in its natural environment. It can be planted in full sun, semi-shade or even in bog or aquatic conditions. The flowers come in a variety of colors, including pink, white, off-white, blue, lavender, purple, yellow and orange. This plant is cold hardy and can tolerate temperatures in USDA Zones 6-9. It is also flood tolerant.
When planting Utricularia sp. (Bladderwort) in a pot, in cold regions, it is recommended to move the pot indoors during cold spells. The pot should be a well draining type, as this plant does not like to stay wet for too long. Keep it lightly moist, but not soggy, in order to avoid root rot or other diseases. Utricularia sp. (Bladderwort) will do best in acidic soil, and using a fertilizer designed for acid-loving plants will help to keep the soil pH balanced. It is also recommended to add a layer of mulch on top of the soil to maintain a consistent moisture level.
Utricularia is a diverse genus of carnivorous plants, with over 200 species found on every continent except Antarctica. These plants can be either terrestrial or aquatic, living in moist-to-wet soils or floating freely in ponds and ditches. Many of the terrestrial species in the tropics are epiphytic.
One of the most striking features of bladderworts is their rootless morphology. These plants do not have traditional roots, instead relying on specialized structures to obtain nutrients. The distinction between stem and leaf is often blurred, particularly in aquatic species. The trapping mechanism, the bladder, is a modified leaf or leaf division, similar to other carnivorous plants.
Despite their unusual appearance, bladderworts are known for their colorful and showy flowers. Both terrestrial and aquatic species have flowers that are often as beautiful as those of orchids, especially when seen in large number
