Dark Blue, also known as Cape Leadwort, Cape Plumbago, and Plumbago auriculata, is a tender perennial flowering shrub native to South Africa. This plant offers an upright, mounding, or climbing habit that reaches 18-48" tall and 20-56" wide. Perennial and semi-evergreen in zone 9-12, Plumbago will die back to the ground at around 20 degrees, returning from the roots in the spring. In warmer regions, foliage is evergreen, and this shrubbing, climbing plant reaches the taller end of its growth potential. In cold areas, grow this plant as an annual or in a container that overwinters indoors. Dark Blue is drought tolerant and attracts butterflies with clusters of blue flowers from spring through fall. It will create an arching shrub or climb a trellis and flourishes in mass plantings or containers in full or partial sun.
Dark Blue Selling Tips
Sell Dark Blue to customers looking for a low-maintenance shrub for a border or an attractive flowering plant for a large container. Plumbago excels in full or partial sun with moderate water, offers clusters of blue flowers with dark blue stripes and semi-evergreen foliage, and attracts pollinators. Green foliage arches gracefully left untended or will climb a trellis or wall. Flowers bloom from spring through fall. This drought-tolerant plant requires little more than regular water. Create a tropical garden by pairing this plant with Allamanda, Bulbine, Cape Honeysuckle, and Firebush, or create a Mediterranean landscape by growing this shrub alongside Bougainvillea, Pelargonium, and Rosemary.
Coach Your Customer
1. Space plants three feet apart in well-drained soil in full or partial sun.
2. Water once a week or more often in drought.
3. In zone 9-12, prune back in late winter or early spring to encourage new growth. This plant will die back to the ground when temperatures dip to 20 degrees but will return from the roots in spring. For customers in zone 2-8, grow this plant annually or in a container to overwinter in a cool, dry place after cutting it back or in a sunny indoor room without cutting it back.

Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
