Is this a mustard green?

[Salaam]

Hello all,

I grew Lacinato kale, Russian red kale, Scotch dwarf kale, and collard greens from seed in the same tray. I planted them all outside and it seems that two of the seeds were not what they said they were! I didn't notice when I was planting them but my wife noticed when picking them.

I have attached photos. They have little white hairs on them. So I am guessing they're some kind of mustard green but I'm not sure. Any help would be appreciated.

Looks like a kale to me. Maybe a crossed seed? They should be good to eat anyway, if you like the flavor.

My guess is Brassica napus (rapeseed/rutabaga green). From your list of kales, Russian red kale is Brassica napus (leaf form), the rest are true kales (Brassica oleracea). All are delicious greens to eat.

The leaf stems of the napus kales snaps/breaks exactly like in your picture, the texture is somehow different from other kales. Grows faster than other kales too. There are many leaf forms and colors of napus kales sold, and it is not uncommon to get few off-types. I have seen similar green individuals growing out from some red napus seeds.

My vote goes for cross-pollinated collard greens or kale. It looks a little too rubbery for mustard to me. But, I don't know how to explain the hair.

I often get surprises when planting when planting seeds that I purchased in bulk... but your pictures are typical of kale as stated above... The little hairs? I get those in kale...

Michihili cabbage has lots of 'hairs', more like spines or bristles, on the outer leaves. I noticed them on napa cabbage too.
I suspect slug defenses.

Thanks for your replies. I've added two photos of the two plants and one photo of the collard greens.

My vote changes to kale (in light of stone's assessment, and the new pictures).

Now that I see the new photos, with it getting more frilly, my vote is also for kale. The earlier photos looked somewhat like the senposai I grow (cabbage x komatsuna), but when I looked at mine closely yesterday, there were no hairs.

Seems on the money for a Scotch kale to me.

Well has it been tasted yet?

[Salaam]

Yes, and we're all still alive! It tasted like kale. But it wasn't any of the varieties I planted.
