Sagittaria Subulata from South America is an ideal, undemanding foreground plant whose short
runners form a compact group. Place individual plants 2-4cm apart. This plant may cause problems
because in certain conditions it suddenly grows to a height of 50cm when it grows older. But if it
is then moved to the background it may become low again. In the aquarium it sometimes sends a
long flower stem to the surface, and small white flowers unfold just above the water surface.
