Bacopa monnieri ‘Type I’ and ‘Type II’

We have had Bacopa monnieri ”Type II” in store for several months now. Compared to “Type I”, it has more oblong, spatulate leaves and a creeping habit. Originally, this plant was introduced to us as Hedyotis salzmannii but it became clear even in submersed cuture, that it was in fact a form of B. monnieri. Flowering experiments soon confirmed this opinion.Due to the different shape of each form, their respective use in the aquarium is slightly diferent. Since Type I grows more upright, it lends itself to being used from mid- to background. At least, in medium to small aquaria. Especially under lower light, growth will be fairly straight. Despite a medium tendency to branch out, sideways growth is manageable and not too rampant. Again, this will depend on illumination: The brighter the lights, the more branching.

Type II is a more prostrate grower and forms abundant side shoots. Overall, it is a faster grower. By virtue of its oblong, narrow leaves (which do not tend to curve inward at the sides as the Type I tends to), you’ll get a nice cushion of geen in the fore- to midground, with a very interesting texture to it. The Type II lends itself very well to making a Dutch style “Street”.

If kept potted and emersed, this Bacopa will form a nice trailing mat and makes a suitable house plant. So, this investment will even pay off in more than one way!


Bacopa caroliniana “Compact”

I was given this plant for specialists and connoisseurs by H.G. Kramer in Winter 2010. Here we have a more compact and slow-growing variety of (quite certainly) B. caroliniana. What differentiates it from the common form is its side shoots which are produced earlier and lower down the stem as well as the more compact growth with somewhat smaller leaves.

I like the compact form, especially for small to medium sized tanks. It is a suitable plant for the mid-ground region due to its moderate growth rate and alltogether more delicate habit. Another benefit that comes with slow growth of course is the lower maintanance. Due to its pronounced tendency to branch out and its compact, dence growth, this is a very interesting new plant which will accompany both bright green and also red plants in the middle ground of any aquarium.
