How much do Peonies resemble Gardenias and are they any way related to each other?

Question

What are the different bloom times and conditions needed as well?

Thanks for your answers!

Answer 1

Peonies and Gardenias resemble each other because they have many  petals layered over each other.

I do not think they are related.

Peonies  can stay in the ground overwinter - very harsh winters like Canada  IF they are cut down in the fall and are well covered with mulch, they will bloom again in the spring - flowering in May and June.

Gardenias need a warm to moderate temperature to grow in.
