Miranda Orange gegen Beverly Orange Mums. Warum blühen sie anders?

Could it be the soil?

Could be a cat like the one user suggested, maybe also the way they watered when growing?
The nursery i work at grows a ton of mums every year from wee baby and as they grow if you water them directly in the middle from above too often it’ll kinda slowly displace the leaves, though its not usually so drastic so maybe the something laid down on it theory is more accurate
