The Story

Plant Bio

Gardenia jasminoides is a classic evergreen shrub known for its intoxicatingly fragrant white flowers and lustrous, deep green foliage. It is a staple of southern gardens, requiring acidic soil and consistent care.

'Prince Charles', also sold as Steady as She Goes®, is a modern cultivar selected for its exceptional reblooming ability, producing fragrant double flowers from late spring until the first frost on a sturdy, well-branched plant.

Uses & Benefits:

This gardenia is a showstopper, offering a nearly continuous display of classic, fragrant white blossoms against a backdrop of handsome, glossy evergreen leaves. It brings a sense of timeless romance and sensory delight to the garden from spring through fall.

Its medium size and dense, rounded habit make it an excellent choice for a fragrant informal hedge, a foundation plant, or a standout specimen in a mixed border. The flowers are superb for cutting and bringing their perfume indoors.

The sweet, strong fragrance of gardenia flowers is particularly attractive to nocturnal pollinators like moths. During the day, they are also visited by bees and other insects.
