i try mass cross breed rose and dandelion.
most of the time you got one of the original plants my estimation is 70-80%.
second option is another flower like tulip, cyazint or blackthorn - my estimation is 15-20%
and thirs is something absolutely different and random like reed, wheat or stick-reed - that is 1-5%
now i am trying crossbreed same plats to make them more elite. and first test are encouraging as I got 5-4-2 blackthorn from 3-3-1 will report when i got more data.
EDIT: ok from another test with 1-3-1 i got 0-0-0 so it can go down. but i hope it can be breed to ultimate 31-31-31 plants.
