What is the Pinwheel Jasmine Tree?
The Pinwheel Jasmine Tree, scientifically known as Tabernaemontana divaricata, is a tropical shrub often cultivated for its star-like white flowers and glossy green foliage. It’s also commonly called Crape Jasmine, reflecting its delicate, crinkled petals that resemble crape fabric.
Remarkably cold-hardy, ‘Pinwheel’ (Cape Jasmine) is a medium-sized evergreen shrub prized for its thick, glossy, lance-shaped dark green foliage and highly fragrant single white flowers with narrow petals. It blooms profusely from late spring to early summer, with occasional blossoms appearing through early fall. This rounded shrub, reaching up to 3-6 feet tall and wide (120 cm), is an excellent choice for small gardens or containers. Plant it in a spot where its captivating fragrance can be fully appreciated!
Key Features
-
Height: Typically grows 3-6 feet in containers but can reach up to 10 feet in gardens.
-
Flowers: Produces fragrant, white, pinwheel-shaped flowers throughout the year.
-
Climate: Thrives in USDA zones 9-11, making it ideal for warmer regions.
-
Toxicity: Non-toxic to humans but mildly toxic to pets if ingested.
-
Other Uses: Often grown for its ornamental beauty and ability to attract pollinators like butterflies and bees.
If you love low-maintenance plants with striking foliage, go for Variegated Crepe Jasmine. Its beautiful, variegated leaves offer a stunning contrast to the white flowers, making it another excellent choice for your garden.
According to one legend, the jasmine was considered a divine flower, dropped from the heavens to enchant humans with its beauty and scent. Its pure white flowers are thought to represent spiritual enlightenment.
Planting the Pinwheel Jasmine Tree
The best time to plant Pinwheel Jasmine tree is during the spring or fall, when temperatures are mild. Here’s why:
-
Spring planting: This gives the shrub time to establish its roots before the heat of summer. It’s ideal if you live in a region with hot summers, as the plant will have time to adapt.
-
Fall planting: In areas with milder winters, planting in early fall allows the roots to grow and strengthen during the cooler months without the stress of heat or drought.
If you’re in an area with exceptionally cold winters, spring is the safer option to avoid frost damage to a young plant.
Choosing the Right Location
-
Look for a spot with partial to full sunlight; aim for at least 4-6 hours of sunlight daily. While it tolerates some shade, more light will ensure better flowering.
-
Ensure the area has good air circulation to prevent fungal diseases. Choose a location protected from harsh winds and frost pockets, especially in colder regions.
-
Plant it near walkways, patios, or windows to enjoy its delightful scent.
Soil Preparation
-
Pinwheel Jasmine thrives in well-draining, slightly acidic soil (pH 5.5–7.0).
-
Enrich the soil with organic compost or well-rotted manure for better growth.
Planting in the Ground
-
Digging the Hole: Dig a hole twice as wide and as deep as the root ball.
-
Positioning: Set the plant at the same depth it was in its container, ensuring the root crown (where the stem meets the roots) is level with the soil.
-
Backfill and Water: Fill the hole with amended soil, pressing gently to remove air pockets. Water thoroughly to settle the soil.
-
Mulching: Apply a 2–3 inch layer of mulch around the base, keeping it away from the stem to prevent rot.
Container Planting Tips
-
Choose a pot with adequate drainage holes, at least 2 inches wider than the root ball.
-
Use a lightweight potting mix blended with perlite or sand for better aeration.
-
Keep the tree in a location where it can receive 4-6 hours of sunlight daily.
-
Watering: Container plants dry out faster, so check moisture levels often. Water when the top inch of soil feels dry.
-
Fertilizing: Feed every 4-6 weeks during the growing season with a balanced, acid-formulated fertilizer.
Growing Pinwheel Jasmine Tree
Consistency is key to growing a thriving Pinwheel Jasmine tree. Here’s how to care for it:
Watering
-
During hot summer months, water 2-3 times per week; reduce watering in winter.
-
Keep the soil consistently moist but not soggy. Crape jasmine are sensitive to drought and overwatering, so check soil moisture regularly.
Fertilizing
-
Use a slow-release or water-soluble fertilizer specifically formulated for acid-loving plants like gardenias, azaleas, or camellias.
-
Look for one with balanced nutrients (e.g., 10-10-10) or slightly higher nitrogen (e.g., 12-4-8) to support foliage and blooms. And feed your tree every 6-8 weeks during the growing season.
-
Organic fertilizers like compost or fish emulsion also work well.
Pruning
-
Trim dead or damaged branches to encourage healthy growth.
-
Prune lightly after the flowering season to maintain the tree’s shape.
-
Prune after the main flowering period in summer to shape the plant and encourage healthy growth.
-
Remove spent blooms (deadheading) to promote more flowers.
-
Trim any dead or crossing branches to improve airflow and reduce disease risk.
Winter Care
-
If you’re in a cooler region (below USDA zone 9), bring potted trees indoors.
-
Place them near a sunny window and reduce watering during winter dormancy.
Potting and Repotting
-
Repot the tree every 2-3 years or when roots outgrow the container.
-
Choose a slightly larger pot and refresh the soil during repotting.
How to Propagate the Pinwheel Jasmine Tree
The easiest way to propagate Pinwheel Jasmine is through stem cuttings:
-
Take a 6-8 inch cutting from a healthy branch.
-
Remove leaves from the bottom half and dip the cut end in rooting hormone.
-
Plant the cutting in a small pot filled with a moist potting mix.
-
Keep it in a warm, humid environment, and roots should develop within 4-6 weeks.
