Common Gardenia, Cape Jasmine
|Unmatched for the sweet, intoxicating fragrance of their creamy white flowers, these are favorite evergreen shrubs in mild regions and a popular houseplant elsewhere. Many varieties are available, including 'Radicans Variegata', with white-variegated leaves, and 'Mystery', an extra-large, double-flowered selection. Excellent as container plants, shrub borders, foundation planting, informal hedges and espaliers. Houseplants often bloom in winter if grown in a warm, sunny spot. Good companions for Azaleas and Rhododendrons, they flower best where summers are warm with partial shade from hot afternoon sun. Need ample water and well-drained, humus-rich soil. Feed regularly with acid fertilizer. If the glossy green leaves become yellow, treat with iron sulfate or iron chelate. Watch for aphids and scale. Mulch around shallow roots. Prune only weak or unattractive branches.
The large, double flowers reach 4 to 5 inches across on some varieties. Plant near entrances or windows where their fragrance can be enjoyed. Avoid wetting flowers when watering.
