Pandorea jasminoides, or Bower plant as most gardeners call it, is a vining evergreen woody plant with thin twining stems. The plant produces white, pink or red tubular flowers in summer, fall and winter. The flowers are fragrant and will grow on very young, soft wood. Bower plant is a moderate to fast grower that will cover an arbor within its first two years of growth. The flowers attract butterflies and hummingbirds, and the plant is hardy in USDA planting zones 9 through 11. Bower plant needs little care once it is established.
Water the plant thoroughly in the spring when first planted. To establish the root system, water the plant every day for two weeks, then cut back to twice a week. During the rainy summer season, water only when there has been a week of dry weather. In the fall, continue to water twice a week when there is no rain. Irrigation will be needed at least once a week throughout southern, warm winters.
Spread a 3-inch layer of mulch in a 3-foot diameter around the plant in the spring. Pull the mulch back from the main stem 3 inches. Reapply the mulch in the late fall as it decomposes, in case of frost over the winter. The mulch will keep the roots warm during that time.
Apply 15-0-15 fertilizer in the early spring and again in early fall during the plant's first growing season. Follow manufacturer’s directions for the amount to use per size and age of the plant. Once the plant is established and is growing well with lush green leaves, discontinue fertilizing.
Put a 2-inch layer of compost over the root area of the plant in late spring and early winter. Water the compost to leach it through the mulch and into the soil to provide the micronutrients the plant needs.
Prune the vines to shape the plant to your desired size just after the blooms die off. In the southern parts of the zones, the plant may bloom through the winter and pruning may have to be done to each branch as the flowers fade; however, pruning is not necessary to the plant's health.
