Grown in a USDA Zone of 9-11, Scutellaria costaricana (Skullcap), a native of Costa Rica, is a great choice for almost any garden. This small shrub usually grows up to 2 to 5 feet in height, with elliptic and oval-shaped leaves that are deeply veined and up to 3 to 6 inches long. It is a highly attractive and low-maintenance plant that thrives best in either partial shade or semi-shade environments. It prefers regular watering, though it does not tolerate too much moisture in the soil.
These beautiful plants produce showy racemes of orange-scarlet tubular flowers with contrasting purple-brown calyx. Blooming year-round with bright light and warm temperatures, Scutellaria costaricana is also a great addition to attract hummingbirds and butterflies and other pollinators. It can be grown as an annual in colder climates, as it prefers a warmer, tropical-like environment.
When planting Scutellaria costaricana outdoors in cold climates or areas, select a sunny spot for the best growth. Be sure to choose a soil that drains well, as this plant does not tolerate water-logging. Compost the soil with phosphorus-based fertilizer and ensure adequate drainage at the roots.
In colder regions where temperatures dip below freezing, Scutellaria costaricana can be grown in pots. Choose a container with plenty of room for root growth and using a light, well-draining potting mix. Place the pot where it can get some sun, at least 6 hours per day. Though it will not be as cold-hardy in a pot, with the right amount of protection and regular care, it has the potential to be a long-term addition to your landscape.
