Flower show highlights

Lalbagh Botanical Gardens, Bangalore is currently hosting one of its biannual flower shows. 

Here's a photo tour of some of the interesting finds...

Venus flytrap is a fine example of adaptation in plants that grow in nutrient-poor soil. These carnivorous plants trap insects and supplement their nutrition with animal protein....

It catches its prey—chiefly insects and arachnids—with a trapping structure formed by the terminal portion of each of the plant's leaves, which is triggered by tiny hairs on their inner surfaces. When an insect or spider crawling along the leaves contacts a hair, the trap closes if a different hair is contacted within twenty seconds of the first strike...

The requirement of redundant triggering in this mechanism serves as a safeguard against wasting energy by trapping objects with no nutritional value...

Another carnivorous plant on display was the Pitcher plant. They have chlorophyll in their leaves but they grow in nitrogen deficient soil. So they evolved the power to catch and consume insects to provide them with the nutrients. The funnel-shaped pitchers are topped with an extension, called a hood, that arches over the opening and helps keep rain out. The plants produce nectar near the opening of the tube that attracts insects and may even contain a chemical that drugs them so that they are more likely to fall into the pitcher. The insect cannot get out of the cup because the walls are smooth and slippery and the walls have hairs pointing down. After the insect is dead, its body rots. Rotting releases the nitrogen from the insect's body. The nitrogen then goes into the liquid and the plant takes in the nitrogen from the liquid...

The Pink Moon Cactus completely lack chlorophyll, exposing the pink pigmentation. Since chlorophyll is necessary for photosynthesis, these mutations are grafted onto another cactus with normal chlorophyll...

Geranium...

Nasturtiums have been used in herbal medicine for their antiseptic and expectorant qualities. They are said to be good for chest colds and to promote the formation of new blood cells.

The flower has most often been consumed, making for an especially ornamental salad ingredient; it has a slightly peppery taste reminiscent of watercress, and is also used in stir fry...
