Lobelia cardinalis

Lobelia cardinalis in my aquarium

Emerse form of Lobelia cardinalis

Common name
Lobelia 

Description
A very slow growing, light-green, easy to keep stem plant. This plant can get more than one meter high, but because of his slow grow it can be used as plant for the front and middle area of the aquarium. 

My experiences
Although it's often said that slow growing plants are more open to algae's is this not my general impression of slow growing plants. In my aquarium, which had lot's of algae's in the time I had this plant for the first time, this plant hardly attracted algae's. Only the old leaves did attract some pointed algae's. 

Now (30-9-01) more than two years later I have this plant in my aquarium again. The top picture on this page shows how the plants look at this time, while the second picture shows the emers form of the plant. Despite of the plants I had in the past, the plants I now have tend to attract more pointed algae while the number of algae in general has been decreased in my aquarium. The reason for this could be because of the stronger light above my aquarium. Though it could also be that the number of algae are (temporarily) increased in my aquarium because in a short time all the plants on the right side of my aquarium have been changed.

Place and lighting in my aquarium
This plant has stood on the left-front and right-front of my aquarium. The lighting I have used for this plant has varied between 0.42 Watt/liter standard TL lighting (2*18 Watt) till 0.63 Watt/liter standard TL lighting (3*18 Watt).
