Tolerant of the toughest conditions, 'Blue Sea Holly' may require staking or support in rich soils. This spiky, architectural character adds interest to our sunny border with its colourful stems and spiny-toothed leaves surrounding the domed blue cones. It looks wonderful planted amongst agastache and coneflowers. Also a superb cut flower, beloved of florists.

Jacob ★★★★★ Oct 22, 2026

Even in my heavy clay soil this plant has thrived, and those unique colorful stems add a great structural element to the garden. The only thing I need to remember is to give it a little stake support when it gets tall.

Carter W. ★★★★★ Oct 20, 2026

Planted these in a sunny spot with poor soil and they’ve thrived without any staking at all. The spiky blue flowers have kept their color through two weeks of heatwave.

I was worried the stems would flop over in my garden, but they stayed perfectly upright even after a heavy rain. The spiky blue flowers are such a unique shape and add a cool architectural look to the border.
