About Grandiflora Star Gardenia
Gardenia jasminoides 'Grandiflora Star' is a moderate-growing shrub in the Rubiaceae family. It reaches around 1.2 m tall and 1 m wide at maturity, with evergreen foliage. White flowers appear for much of the year.
Where to grow Grandiflora Star Gardenia
Grandiflora Star Gardenia suits subtropical and warm-temperate climates and grows best in full sun and part shade or morning sun. It is frost tender, so protect it from hard frosts or grow it in a sheltered spot or pot.
Soil & planting
Grandiflora Star Gardenia does best in free-draining and acidic soil. Plant into well-prepared ground, firm the soil around the roots and water deeply to settle it in. For a screen, space plants about 60 cm apart.
Watering & feeding
Grandiflora Star Gardenia does best with regular, moderate watering. Feed as new growth begins, following the rate on a balanced garden fertiliser. For the first year, favour occasional deep watering over frequent shallow drinks so roots move into the surrounding soil.
Pruning & care
Prune Grandiflora Star Gardenia after flowering to keep it compact and encourage the next flush of blooms. It clips well, so trim two or three times a year for a formal finish. For most gardens, it is moderate maintenance.
Using Grandiflora Star Gardenia in the garden
Grandiflora Star Gardenia earns its place for its fragrance, pots and courtyard containers, a feature or specimen planting and a fast screen or informal hedge. It is equally at home in the ground or a large pot on a balcony or courtyard.
Companion planting & design
Grandiflora Star Gardenia sits most comfortably beside plants adapted to regular, moderate watering and subtropical climate. A small cluster gives stronger visual impact than isolated plants scattered through the garden.
Good to know
It is regarded as non-toxic and pet-safe.
