Flowers ???

[Mongrels]

Tried this myself a couple of weeks ago and it worked - just farm a lot of seeds and try using them on grassy plot during daytime. I needed like 64 seeds to get a 4-5 red flowers (of course I got some yellow ones and pumpkins as well. So, yeah it works, but it takes some effort.

I have also heard rumors that they grow further away from spawn, like at 2000 mark, but I havent investigated that.
