What is a foreground plant?
Foreground aquarium plants are ideally aquatic plants that are placed at the base of a hardscape layout, near the midground area. These are low-growing aquatic plant species that will form the beautiful carpets of green commonly seen in the aquarium hobby.
How does hygrophila Polysperma reproduce?
H. polysperma has the ability to prolifically reproduce vegetatively through brittle stem fragments and even detached leaves which are capable of rooting and developing into new plants (Kasselmann, 1994; Sutton, 1995).
How do you take care of hygrophila?
In its natural habitat in the wild, the hygrophila corymbosa enjoys full exposure to sunlight, but in a tank, it does well with moderate to intense lighting. The pH level of the water should be kept between 5.5 and 8 with the hardness level between 2 dGH and 15 dGH, which is fairly soft.
What is a background plant?
A background plant is a type of plant that provides a backdrop for smaller plants. A hedge can be a type of background plant design, if the hedge is lined with smaller flowers.
Is hygrophila a stem plant?
This stem plant is bright green in color and can sometimes change colors based on the amount of lighting it receives. The hygrophila corymbosa is known to change to a dark green color, as well as pink, red and even purple. When partially submerged, this aquatic plant has the ability to produce pink and purple flowers.
What is Hygrophila polysperma?
Hygrophila polysperma is a fast-growing and fast-spreading invasive that can outshade and therefore outcompete other submersed plants; it can occupy the entire water column; many adventitious roots at stem nodes means that fragments can easily grow.
What is Hygrophila in biology?
Hygrophila is a fast-growing aquatic invasive that can outshade and outcompete other submersed plants. It can grow to occupy the entire water column and forms dense mats, blocking light penetration below. Hygrophila produces adventitious roots at stem nodes, therefore fragments can easily grow into new plants.
What does a polysperma plant look like?
H. polysperma is an herbaceous rhizomatous perennial aquatic plant with squarish stems that are ascending or creeping. The stems are mostly submerged, and are usually rooted in the substrate, though can also root freely at floating nodes. The submerged stem is very brittle, and can grow over 6 feet long.
Why was Hygrophila extirpated in Virginia?
Extirpated in Virginia due to freezing temperatures in the 1970s (Nault and Mikulyuk 2009). Impact of Introduction: Hygrophila polysperma forms dense monocultures that exclude native plants and is a superior competitor because of its low requirements for light and rapid growth (Spencer and Bowes 1985).
