Why a single pot of Canary rose blooms two kinds of flowers: an analysis

Do you know why a single pot of rose can bloom 2 different kinds of flowers?
Today I saw someone in the forum saying, why does the same potted Canary rose bloom 2 different kinds of flowers? Let's analyze it together.
A normally blooming Canary: the Canary rose variety is a blooming machine, and every bud point can become a supporting point for flowering. A Canary in full flush is very spectacular.
Question: So why do some Canary roses bloom so unattractively?
This is because of high temperatures, which cause deformed flowers. These are flowers opened under poor conditions, so naturally they do not look as good. Especially for roses opening their first flowers, they are usually pruned; if not pruned, the flowers they open are also unattractive. In high temperatures Canary basically rarely blooms, but the ones that barely bloom are still acceptable.
After autumn arrives, roses need a lot of fertilizing. We can choose a good nutrient solution to promote root development, then apply granular fertilizer to add nutrients. This lets Canary produce more shoots, and only then is a full flush possible.
Remember water control and sunlight; basically, making a potted Canary rose bloom a second time is also impossible!
