Secret Garden Growers Caryopteris incana

You should prune Sunshine Blue hard in the spring. Because this variety blooms on new wood, cutting it back before the growing season begins encourages vigorous new growth and a more abundant floral display later in the year.

This shrub is hardy down to USDA Zone 5a. As a deciduous plant, it will lose its leaves in the winter and go dormant, returning with fresh growth once temperatures warm up in the spring.

This plant thrives in full sun, meaning it needs at least six to eight hours of direct sunlight daily. Planting it in a spot with adequate sun is essential for maintaining that signature vivid gold foliage and ensuring a strong bloom cycle.

Yes, Caryopteris incana is generally avoided by deer and other common garden pests. While no plant is 100% deer-proof if food sources are extremely scarce, this shrub is a reliable choice for gardens where wildlife pressure is a concern.

The most important requirement is well-drained soil. It does not tolerate 'wet feet' or heavy, soggy clay, so ensure your planting site drains well to prevent root rot.
