I had to start from scratch to get a Animal Crossing Bells green mum. First place yellow and red mums together. Then some yellows will predominate. Set the new and only the new yellows together. Those will produce purples.

I have some spare hybrid reds (the type guaranteed when bred together make blue roses) if you would like them.

Thanks so much for the deal, but I'd like to try and get them on my own. I know that it's kinda silly, but I feel like the accomplishment of getting all the flowers will feel greater if it's self-sustained.

Learn from my mistakes! Not many purple mums are created equal. Each flower has a'DNA' of sorts with its breeding history. Shade alone will not be enough.

To be able to breed green mums, first you need to breed red seed mums with yellow seed mums. As a result you'll acquire fresh yellow mums with red DNA.

Separate the new hybrid yellow mums and strain them together to create the exceptional purple mums. These mums are going to have the red and yellowish DNA.

Independent the new hybrid mums and strain them together to produce green.

Be sure that the purple mums are out of literary (Hybrid) rather than from White mums... I made the mistake of mixing my Purple mums from the resources and had to redesign, but after you got the appropriate purple you can get Green quite quickly (also feasible to breed straight from Hybrid yellow).

For Blue Rose I followed the simple 4-step method (not the 9-step which seemed way too complicated) and it took approximately 6 weeks to the first one which I then cloned.... Haven't gotten any more out of my initial 4-step flower beds however, the buy Animal Crossing New Horizons Item cloned ones are replicating fairly fast. (I had to redo the rose method like I previously followed some incorrect breeding graph )
