full height ludwigia and lobelia
Ludwigia breaks the surface

Figures are approximate, as they say.  When planning a planted aquarium (and there should be some type of plan!) it’s important to consider the expected maximum height of plants in the layout.  I went wrong previously planting echinodorus radicans, a fine plant but much too large for this aquarium.

After not trimming back the ludwigia last week today it managed to reach the surface of the water today.  This version of ludwigia, ludwigia mini ‘super red’ is listed online as “Dimensions: grows up to 30cm” however in this aquarium it is 41 cm from the aquasoil floor to the water surface, so this plant has overachieved.

I can’t complain and I’m glad it’s healthy.  I’ll give it a trim today and replant some of the better looking top portions to have it fill in a little to the right.  Stem plants like the ludwigia are pretty flexible that way:  you can trim them to pretty much whichever height works for you, just the growth rate and how much you trim will determine how often they will need this type of maintenance.

Afternote: 
Digging around a bit more on the Tropica entry for this plant it says in the “Plant info” section in the ‘Height’ entry if you click on the +/- expander button:

Height:10 – 30+
Average height (cm) of the plant after two months in the tank.

so to be fair there is a little + sign after the 30 and it does say ‘after two months’ and it has been three months in tank (nearly to the day) since it was planted, so I suppose it’s “fair play” to the description, even if 30+ is actually 41…
