Sagittaria Subulata is an easy to grow rosette plant that will thrive in most aquariums.


The plant typically grows to a height of 8 to 16 inches, usually tallest under high light conditions. The width of each stem is about .25 inches, based on leaf growth. The leaf is linear to strap shaped light green submersed.

In order to achieve strong growth the substrate should contain iron, while light is less important. Planted in a group or as a standalone this aquarium plant can be striking. It can grow well in both hard and slightly soft water. Optimum growth temperature is 64.4 to 82.4 degrees, but it can withstand temps from very low to 84 degrees.

Sagittaria subulata requires low to high lighting (1.5 - 4 watts/gal), grows quickly and propagates by runners which will form a dense grouping producing 2 - 3 leaves and one runner per month. In the aquarium it sometimes sends a long flower stem to the surface, and small white flowers unfold just above the water surface.
