- Description
-
St. Andrew's cross is a native semi-evergreen shrub in the St. John's wort (Hypericaceae) family. It is native to the Eastern USA, Mexico and Central America. In NC it can be found growing in the coastal plain in light sandy soils of prairies, open pine-hardwood and hardwood forests, thickets, grasslands, and bogs. This small shrub will grow 2-4 feet tall and 1-3 feet wide. It is a wildlife-friendly plant.
St. Andrew's cross prefers average moist to dry sandy or loamy soils in full sun to partial shade. It is very adaptive to various conditions and is fairly drought-tolerant but not salt-tolerant. The small yellow flowers have 4 sepals that form an "x" and attract various pollinators. It has a fairly long bloom season during the summer. In warmer climates, it will bloom nearly all year.
Use this plant in the native/pollinator garden or any naturalized area. It can also be planted at pond or stream margins in well-drained soils. Propagation is by seed or stem cuttings.
Insects, Diseases, and Other Plant Problems: No significant problems. Fairly short-lived.
