Scientific name for 'Dwarf Sagittaria'..
Colin asked about the scientific name for 'Dwarf Sagittaria'
Sagittaria subulata is common and widespread in South and North America. It
is a modest plant and therefore a good starter plant, though it prefers a
relatively fine substrate. The narrow leaves it placed in a rosette and
tubers are sometime set on the offshoots. Placed in the foreground it soon
develops a dense cover from offshoots. For years Sagittaria subulata
maintains its low growth form but dependent on for example age, light
intensity and population density it suddenly stretches up to a height of 50
cm and sets flowers. Such plants are often mistaken for Vallisneria.
Replanted in the background of the aquarium Sagittaria subulata often turns
back into the low growth form.
Part of the world America
Height 10-30 cm
Width 10-15 cm
Light requirements high-low
Hardness tolerance soft-average
pH tolerance acid neutral
Most useful as a submersed grass in aquariums and as an oxygenator in ponds.
Ribbon shaped leaves grow up to 12" long and 3/8" wide. Plant reproduces by
runners and can form dense colonies which become dense enough to stabilize
soil in ponds. In shallow water small, dark green, ovate leaves with small
brown speckles are produces. Small, white flowers float on the water's
surface or are held slightly above it.
I hope this helps, James
