The flowering period of the magnolias begins in March and is not done before mid-July. Perfumed flowers.
I know of ten species here.
An eleventh magnolia species – Magnolia acuminata – grows at Winterthur. However, I cannot tell it apart from Magnolia tripetala.
Star Magnolia (Stellata), non-native (Japan), flowers in March/April.
Magnolia Kobus (Japan), flowers in April.
The Kobus in early March, 2022
Merril magnolia x Loebneri – also grows at Winterthur.
It is cross between Magnolia stellata (star magnolia) and Kobus magnolia and was grown from open pollinated seed in 1939 at the Arnold Arboretum of Harvard University.
It has the sturdy frame of Kobus and the flower shape of the star magnolia.
Yuan Magnolia (heptapeta, China) blooms in April
