Petrea arborea, commonly known as Blue Jasmine, is a large shrub that can grow to a height of between five and ten feet. It is native to tropical America and is grown in USDA zones 9 to 11. Blue Jasmine is a delightful and attractive flowering shrub that will brighten up any outdoor space.
This shrub requires little maintenance but will require moderate watering during dry periods. It loves full sun and should have consistent access to plenty of bright, direct sunlight. If planted in an area with too little sun, Blue Jasmine may become less vigorous and the flowers may not be as plentiful and vivid.
When given the right care, Blue Jasmine will put on a spectacular show of bluish-plum flowers in the late winter. These blooms also come in lavender and purple shades that will attract butterflies and hummingbirds.
When growing Blue Jasmine in areas where it is not hardy or in a contained environment, such as a pot, it is important to provide extra protections during the winter. This shrub can thrive in colder regions but will require extra perseverance. Maintaining the right soil type is essential. It needs a well-draining, slightly acidic soil and will also require additional protection in the winter and supplemental watering. Mulching is highly recommended, as this will help insulate the root system and will also help the soil stay moist.
Overall, Petrea arborea is a beautiful and hardy shrub that will bring a burst of life to any outdoor space. With the right care and attention, it will reward you with stunning blooms every year.
