MY COLLECTION of Venus flytraps grows in a hanging pot filled with sphagnum moss submerged in water. Few plants would survive these extremely swampy conditions, but the flytraps thrived in the nutrient poor conditions. They only needed to drink the swamp water as they fed on the flies and other insects they so effectively caught. Plants are not known for being able to move. The Venus flytrap is an amazing exception. The traps take less than half a second to close. Each side of the trap contains three hairs. An insect would brush against one hair and nothing would happen. When they brush against a second hair, the trap would suddenly close. They close through the cells on the outsides of each side of the trap suddenly growing, causing it to quickly close. The trapped insect dies and the flytrap feeds on the decomposing remains. |
