This weekend, my wife and I took our dogs to a reservoir near our house that we like to visit this time of year. We probably would visit it more often, except that most of the year, it is completely covered by many feet of water. In the summer, they close off the dam upstream, and the reservoir turns from lake to field, with lots of open space for our energy laden dogs to run.

Our weimaraner/lab mix, Bella, galloped from place to place, clearly enjoying herself. Our lab/spaniel mix, Jen, enjoyed the area more at her own pace, but had a good time nevertheless.

Occasionally, Bella would decide to ambush Jen, which then brought on a flurry of tails, claws, and teeth, playfully pouncing upon each other. The field itself was laden with yellow wildflowers, stretching for a far as you could see.

Last year when we came, all of these flowers had already melted away, and we were left with hitchhiking seeds on our pants, shoes, and tails (dogs). I wasn’t really paying too much attention to the aquatic plants this time, but I did spot some Rotala ramosior, Lysimachia nummularia (Creeping Jenny), and a Polygonum species.

Combined with the beautiful, crisp weather, we had a nice time walking through the wildflowers, and looking for wildlife. We spotted a number of minnows, and a few bass in the brook and feeder streams.

We hope to get out canoeing here next year once the water is high enough. Hopefully that will allow us to further explore more of the area, even though I doubt our dogs will be allow for that trip!

It’s been almost three months since I tore down my 40G aquarium, and restarted it with a substrate based on earthworm castings produced from my kitchen scraps. From the beginning I experienced great growth, but I also had a huge outbreak of hair algae. I’m still not sure whether this was leftover algae that came in from the previous setup, or whether it was spurred along by the earthworm castings. Either way, it’s gone now, and the tank it doing great.

The aquascape has changed a fair amount, as I’ve pulled out a significant amount of the hardscape I originally placed, largely to find room for a smattering of new plants that I needed to house. The Ranalisma rostrata has just about filled in the foreground. The right side of the tank is basically just a growing out space for various stems including Ludwigia sp. ‘Araguaia‘, Rotala sp. ‘Araguaia’, Blyxa alternifolius, Rotala sp. ‘Mini Type I’, and a Limnophila species. Due to all of these plants, I don’t envision this tank ever becoming a cohesive aquascape unless I’m able to setup a farm tank to transfer some of these out. The main thing, is that I’m quite impressed by the substrate sustained growth, with zero dosing. Comments welcome!

Proserpinaca palustris is a plant that I have long sought after, but only have recently started growing. The funny thing is that it’s actually a native plant where I live, but it’s not a plant that’s often kept by aquarists. The most interesting thing about this medium difficulty plant is the vast difference between its emersed and aquatic forms.

Emersed, the plant exhibits leaves that look a little bit like rosemary, except with serrated edges. Submerged, however, Proserpinaca palustris looks like a totally different plant. The leaves are saw-toothed, being much more ornate than your typical Myriophyllum or Ambulia.

Under intense light, these leaves can actually turn bright red. Proserpinaca palustris should grow under most conditions, but the bottom most leaves will melt away except until moderate light conditions. The advantage I see in Mermaid Weed compared to Ambulia or Myriophyllum is that it grows much slower, while the others tend to overtake your tank. I’m really enjoying this plant, and hope to use it extensively in one of my future aquascapes.

On Saturday, GWAPA had another packed meeting at Kevin’s house in Silver Spring, MD. This month, over thirty folks showed up to hear about soil substrates in the planted aquarium. One of our members, Sean, is the originator of the soil substrate recipe that so many people are starting to use in the hobby. It was popularized by AaronT and others on Aquatic Plant Central, and we got to hear the soil method straight from the source.

In addition, we had another large auction — just look at all the bags of plants! I came away with a few things, such as Polygonum sp. ‘Porto Vehlo’ and Rotala verticillaris, and sold off a few things myself. We also debuted GWAPA’s new logo design, which you can see above.

All-in-all, it was another great meeting!

Hygrophila difformis var. ‘variegated’ is a new variety of Water Wisteria that grows similarly, but has white veins, giving it a nice variegated look. Just like regular Wisteria, this plant can easily outgrow the space that you allot for it, but if you’re looking for a plant to fill out the corner of your aquascape it might be just what you’re looking for.

One thing to notice is that not all of the leaves exhibit equal variegation. Some contrast quite significantly, while others are hard to differentiate from a regular wisteria leaf. This can occur on leaves along the same stem, even.

Overall, Hygrophila difformis var. ‘variegated’, it’s a fast grower, a nitrate suck, but most importantly, a pretty plant.

Update: I learned today that this variegation is caused by a virus affecting the chlorophyll in the veins, and can be exemplified by low nitrates. Don’t worry, the virus is self-contained, and causes no danger to this or other plants.
