Plants for Rainwater Diversion Trench Project

Hola.

I'm currently working on a rainwater run off pipe to divert water from entering the foundation of two houses. We are using black corrugated pipe with gravel inside of a trench to divert the water.

I'm interested in what vegetation could be used to: 1) Prevent erosion on the graded soil which carries the water to the trench ( away from the houses) 2). Provide some sort of medicinal/edible product.


I wanted to throw this out there to the permaculture minds to see what suggestions may spring up.

A photo is included in this post to give an idea of what micro climates are available. The gap in between the houses runs East to West. So It gets a fair amount of sun in mid summer - especially mid day. It seems to be a fairly moist area as moss grows on many of the rock and concrete surfaces.

I don't think enough water will be held in the soil/ gravel to grow cattails.

Let me know what yall think.



Thanks!
Chris

Where you can't plant cattails, plant chufa.

Ha! A saying of the wise.
Thanks!
From my little bit of research here I think I may have to invest in some Chufa seeds.

C.esculentus is known as one of the world’s worst weeds. It is a weed for over 21 crops in more than 30 countries around the world.[4] The plant is extremely difficult to remove completely from lawns and gardens, where it is considered an intrusive weed. This is due to the plant having a stratified and layered root system, with tubers and roots being interconnected to a depth of 36 cm or more.[5]

Despised by the despicable...

I have a new respect for Chufa.

Saw a few places to get it online (many of which were for food plots for wildlife) . Any resources that yall might suggest?

Thanks!
