In cooler climates, Bouvardia ternifolia (Scarlet Bourvardia) should be grown in pots and brought indoors before the cold weather arrives. Plant in well-draining, lightly acidic soil and place it in an area that gets a minimum of 4-6 hours of direct sunlight a day. Water regularly while the plant is actively growing and reduce watering in the winter or when the plant is dormant. When growing in a pot, it is best to repot every 2 to 3 years, as the growth rate of this small shrub is quite fast. In USDA Zones 9-11, the mature plant can manage temperatures as low as 30°F for a short time, but it is advised to give it extra protection with mulch or frost blankets if the cold weather will last longer than usual.
Whether you are looking to add some color to an outdoor patio, a terrace, or a balcony, Bouvardia ternifolia
will be an excellent choice. The bright, red, crimson and vinous flowers of this small shrub are extremely fragrant and will attract butterflies and hummingbirds during the day. Keep in mind that it will need regular water, plenty of sunlight and some protection from the frost during the cold season, and you will be able to enjoy its beauty for many years to come.
