Know before you buy
Yes, it works beautifully in containers. Because of its versatile growth habit, you can let it trail over the edges as a 'spiller' or provide a trellis if you prefer a more upright, climbing look.
Royal Cape Plumbago is evergreen in its preferred hardiness zones of 9 and 10. If you live in a region that experiences frost, the plant may lose its foliage or suffer damage, as it is not cold-hardy.
For the most abundant cobalt blue flowers, plant it in a location that receives full sun. While it is heat-tolerant, it requires consistent sunlight to maintain its bloom cycle from spring through fall.
Yes, it is considered deer-resistant. While no plant is completely deer-proof if food sources are scarce, the Royal Cape Plumbago is generally ignored by deer in most garden settings.
Once established, this shrub is quite drought-tolerant and prefers low water. You should allow the soil to dry out slightly between waterings, ensuring it is planted in well-drained soil to prevent root rot.
With a mature width of 8 feet and height of 5 feet, it has a spreading habit. You can prune it back after the main flowering season to control its shape or encourage denser growth, but it is generally low-maintenance.
