Star magnolia hybrid ‘Betty’, in the Display Garden has tepals reddish-purple on the outside and white within. Larger magnolia hybrids involving our native cucumbertree (Magnolia acuminata) also bloom in April and early May. In the Display Garden these include Magnolia ‘Yellow Bird’ on the northeast side, pink and white ‘Daybreak’ in the Arthur S.
