Introduction: Concept of the aquatic plant house
Most tropical aquatic plants don’t spend all their time underwater, but have adapted to changing water levels. During the rainy season, they’re entirely covered by water. As it gets drier, water levels fall and they appear above the surface. Most aquatic plants blossom during this phase: only a handful of plants bloom underwater. This is because water isn´t an effective transporter of pollen. Plants that bloom above water are usually pollinated by insects that carry the pollen from flower to flower. If a plant were to release pollen directly into the water, it’s much less likely that it would reach its target.
The Aquatic Plant House is arranged in that way that you can see submerged plants in
the aquariums, while they are presented in their surface form in the basins on the
opposite side. Notice that the underwater leaves often are finely slitted to reduce
their resistance to water currents. The leaves that appear above water mostly have
entire margins, or are at least less divided.
You’ll find few flowers in the aquariums, but once you see the same species in the
swamp basins, you’ll realize that our aquatic plants are definitely belonging
systematically to the flowering plants.
