Haha yeah, it seems to be easier to gather all the black tulips that the orange ones spawn and have them breed.
Also purple pansies seem to be really hard to breed. I have three and they refuse to breed. Meanwhile I have 20 blue roses and 5 purple tulips
That doesn't surprise me. I saw a duper selling them at 250k for a blue rose, 350k for purple tulip and 500k for a purple pansy. Sounds about right.
