It's nearly September and there seems to be a new urgency in the air. Now we have taken our honey the honeybees, battling wasps at the hive entrance, are building up stores ready for winter. The butterflies now look very ragged and faded, as do this year's Bumblebees - although the new queens look pristine, and are feeding frantically to build up fat for their hibernation. I'm acutely aware of the need for nectar flow before the ivy flowers, and for us although Verbena and some Asters seem to do well for insects at this time of year the plant that ticks all the boxes is Sedum, or Stonecrop (spectabile) and Orpine (telephium). The large flowerheads with their scores of florets are perfect for most pollinators. We've devoted a nice big section of a sunny southwest facing border to it, where I grow three different varieties in order to ensure seamless foraging from late August to October. As ever, the fancier the cultivar the less helpful it is - I've had several failed experiments.
