Description
In a rosette growing aquarium plant. This is a relative new aquarium plant which is a hybrid between Echinodorus schlueteri 'Leopard' and Echinodorus barthii. The plant has red brown leaves with black spots. On the older leaves the spots tend more to dark red.

My experiences
I've had this plant in my aquarium for almost 7 months. After about  3 till 3.5 months the plant had reached a height of about 35 cm. Up till this plant started to form flower stems this plant had not given any troubles and also had a good recistance against pointed algae. The colors of the leaves of my plant did not match the description given above (as found on the site of Tropica). In my aquarium the plant had more green leaves with a bit of red in it and the spots were already dark red on the new leaves, in stead of black. The second picture on this pages shows how young leaves of this plant looked in my aquarium, but most of the red color disappears when the leave became older. The color difference between my plant and the description given by Tropica could maybe be because the light above my aquarium was not strong enough to develop the colors as described by Tropica, but even when I placed a third fluorescent light above my aquarium the colors still stayed the same.

After about 4.5 months this plant began to form a flower stem. About two weeks later the plant formed the first flowers on the flower stem. These flowers are formed on small braches on the flower stem that keep the flowers above the water surface. The flowers only last for one day and are colored white with a yellow hart (see third picture). A couple days after the first flowers the plant also started to form adventitious plants on the flower stem (see fourth picture). At first the adventitious plants had no roods but after about 2 weeks the first roods where formed. At about the same time the plant started to form a second flower stem. Though after about 6 weeks since the first flower stem was formed it looked like the plant didn't grow as good any more. Therefore I removed the second flower stem, because I though this second flower stem could maybe cost too much energy of the plant, but soon the mother plant completely died of. So after 6 months I only had left a flower stem with a number of adventious plants on it. I suspect that this plant will always die of after it has set flowers, although I couldn't find an affirmation on this in any books, although I could find out that the same thing happens with a number of other Echinodorus species. One thing that is noticeably is that after the first flower stem was formed the plant kept making new leaves till the moment it died of, although the height of the plant had decreased to about 30 cm high. 

About two and a half months after the forming of the first flower stem I have removed the last part of the plant from my aquarium. At this time three adventious plants were fully grown and could be taken of from the 90 cm long flower stem. Noticeable was that all of the three plants that were fully grown were formed at the time the mother plant was dying of, while the earlier formed adventious plants stopped growing after some time and didn't grow large enough to take of from the flower stem.

Place and lighting in my aquarium
This plant stands in the middle 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).
