I love this! Another interesting plant from Beth Chattos garden!
We are all grappling with how to garden best in this long, hot dry heat, and the big question I keep hearing is- what to plant. As this year, sadly, many if or usual reliable plants are dying, yet others that are well adapted to these conditions, are thriving. Are you thinking about changing your borders to include more drought tolerant plants?
Or are you waiting to see what kind of weather autumn brings?
Our Plant of the Week πͺ΄
This striking selection was chosen by Marshall Olbrich, whose nursery near San Francisco was visited by Beth Chatto. It was selected for its distinctive silvery-grey foliage, which becomes almost white during prolonged dry spells, providing a beautiful contrast to its vivid scarlet, trumpet-shaped flowers in late summer and autumn. Like many of the former zauschneria species, it thrives in full sun and well-drained soil. It is also known by the synonym Zauschneria californica 'Olbrich Silver'.
The taxonomy of this group has changed considerably over the years, with several species being reclassified. Epilobium is a diverse genus of mostly herbaceous perennials, although some species can be rather weedy. They typically bear four-petalled flowers, either on slender stalks (pedicels) or forming elongated tubular blooms.
Flowers provide an important source of nectar and pollen for bees and hoverflies, while the foliage serves as a larval food plant for a range of moths, including the spectacular elephant hawk-moth.
Native to the arid regions of western North America, these produce brilliant orange to scarlet tubular flowers adapted for pollination by hummingbirds. Although hummingbirds are absent in Britain, hummingbird hawk-moths are capable of accessing the nectar in the intended way. More commonly, however, bees simply bite through the base of the flower tube to reach the nectar, bypassing the flower's pollination mechanism, a behaviour known as nectar robbing.
Taxonomic revisions continue within the family, and some species that were once included in epilobium have now been transferred to the genus chamaenerion.
