Hebes offer impact and structure in the garden for minimum effort. We've selected this slow-growing, compact variety for its stand out summer flower spikes, which transform from electric blue to pure white. Hebe 'High Voltage' performs perfectly in large pots or out in the garden, proving bone hardy to whatever the British winter throws at it. In fact you'll be hoping for freezing winter temperatures, which will encourage the foliage of 'High Voltage' to take on a delectable bronze hue!
