Surely you have something better to do with your time? In the border enjoying the sun to the south of the Herbarium is a large group of Kniphofia caulescens. Not the brightest flowers in the genus but with the glaucous grey foliage and masses of muted orange flower spikes another welcome introduction from South Africa.
As the elongated buds pop open the lemon filaments extrude terminating with a yellow anther. As these fade they congeal around the stalk in a brown mass. If time allows pull these off to keep the clump looking fresh. I have to admit there are better jobs and do beware of wasps.
