The odd name really means something - Known and Recorded Origin (Karo) found near the River Esk in New Zealand. "Golden" speaks for itself.
Hebes come in a wide variety of colors and leaf types, but Hebe 'Karo Golden Esk' is perhaps the most unique of them all. Its vibrant green leaves are so small and grow so tightly together, this small shrub resembles a conifer. Like most other hebes, 'Karo Golden Esk' has summer blooms, but the white flowers are borne on old wood, and often aren't visible. Grown primarily for its bright green to golden foliage, this variety is a stand out in container planters and hanging baskets, as well as in sunny borders and mass plantings.
Hebe ‘Karo Golden Esk’ is a rounded, robust whipcord shrub with spreading crowded of whipcord like branches reaching about 30cm high and up to 80cm wide. The plants has a texture that could be taken for a conifer Its very small anvil shaped closely appressed leaves are almost overlapping, green in summer, yellowish in winter.
Unlike other whipcords hybrids 'Karo Golden Esk' will flower. In spring and summer white flowers (up to 8) are packed densely on terminal inflorescences.
It is a natural hybrid between Hebe odora and Hebe armstrongii, found in 1988 by Dr Brian Molloy near the Esk River on river terraces and bogs in East Canterbury, South Island, New Zealand. Karo is an acronym for ‘known and recorded origin’.
It was given a Royal Horticulture Society Award of garden merit in 1993.
