Yellow mandevillas are just recently gaining recognition. The flower color is almost neon yellow throughout. Grows as a vine-like shrub when it is young. Left to it own devices, it develops into a sprawling vine climbing over nearby shrubs, trees and other structures. Flowers are about 2-3 inches across, produced year-round on stem tips, although the plant is not covered with flowers like the Allamanda. There are usually some flowers on the plant all year long. Flowering period: June-October. All parts of plant are poisonous if ingested. Handling plant may cause skin irritation.
Utricularia is the largest genus of carnivorous plants with more than 220 species that occur throughout the world. They are found on every continent except for Antarctica. Some are terrestrial species found in moist-to-wet, often acid soils, and in sphagnum moss, while others are aquatic, preferring to be floating freely in quiet waters in ponds and ditches. Many terrestrial species in the tropics are epiphytic.
The bladderworts present a rather unique morphology. First of all, the plants are entirely rootless -- completely giving up the normal plant way of obtaining nutrients from the root system. Also, the distinction between stem and leaf is often vague, especially in the aquatic species. The trapping mechanism, the bladder, is a modified leaf or a leaf division morphologically, in general conformity with all trapping structures found in carnivorous plants of other genera. The flowers are generally quite colorful and showy for both terrestrial and aquatic species, especially when seen in masses. Some of these flowers compete with those of orchids in their beauty.
