Sagittaria
The leaves of these paludal plants that are above water are arrow-shaped, while
the submerged ones take the form of thin ribbons. Take care not to push the rhizome
too far into the soil: the plant can be held in place by a curved piece of wire.
Vegetative multiplication occurs by means of seedlings formed on a runner, which
can took root on their own, or with the help of the aquarist. The runner can then
be cut off.
Sagittaria graminea
There are several varieties of the narrow leaf arrowhead, which differ in the
length and width of their leaves. They all prefer moderate lighting, soft or slightly
hard water, and an approximately neutral pH. Size: 40 cm.
Sagittaria sagittifolia
The amphibious arrowhead is quite common in calm waters in Europe, especially
in garden ponds, where it resists the winters, although it prefers sunny areas.
Size: 40-50 cm in water.
