Backyard Aquaponics
A place to discuss aquaponics

Hi KE - Its a cheap packet seed mix we get here in Australia (DT Brown for what its worth)

Packet says "Cress - Fine Curled" Lepidium sativum

it definitely has leaves like a small coriander, it packs a punch in the pepper-mustard taste.
And it costs like $1-$2 a packet and get heaps of seed.

Our winters here (Perth WA) are relatively mild with 2-5 degrees at night and 15-20 degrees at day.
For me the main issue is the side of house with all my aquaponics is in shade pretty much all winter except for about 1-2 hours in the afternoon. My water temps sit around 10-15 degrees.

Doesn't seem to worry the cress but it does go even better as it begins to warm.

I have also grown an Asian Water Cress variety but no longer have the packet.
That was similar and you could eat either as seedlings/sprouts or as the plant developed.

Another type which goes by the classic name "watercress" is Nasturtium officinale.
I think that is what I had before but it is less common in the 'cheap' seed packet brands.
Looks like that may be what the OP has based on web images - but not much difference.

Apparently it will cure you of various things.... another unheralded superfood.
"Watercress contains more vitamin C than an orange, more calcium than milk, more iron than spinach and more folate than bananas"

Apparently in EU you have a choice of English, Dutch or French Cress/Watercress.
You will be pleased to know that google says the English one is superior
(well one article anyway). But doesn't say what its scientific name is.

Changed to 1g pots with lots of drilled holes. Nine and blood meal mixed with gravel, Placed where water flows ..... fingers crossed

Finally, progress. Now question: Can watercress handle Seattle winter? it does go below freezing, but only for a few days.
