The millenium garden features ponds, waterfalls and a formal rill which leads the eye to the magnificent valley and hills beyond.
A tiny rill gradually became a boisterous stream, and the boisterous stream grew into a great river, which spread to all sections of the administration and ended by inundating the whole country.
For moist spongy spots near the rock garden, or by the side of a rill, it is one of the best plants, but its beauty is best seen when it is allowed to ramble over rich, muddy soil.
Crossing a water rill, one passes through an arched doorway into the night garden.
