Hesperis, otherwise known as sweet rocket, is a beautiful, almost phlox like plant, with a soft, delicate purple/mauve colour flower and as the name suggests, a lovely light and sweet scent, which gets stronger as the evening draws in, which incidentally is a clue as to what it wants to attract – moths. Another good feature about this plant is that it becomes almost iridescent at night, perhaps in a further effort to attract night time visitors. Plant this near a seating area, maybe a place you use to wind down in the evening as that way you’ll enjoy its scent to the full. Hesperis is a bi annual, so will grow roots and leaves the first year, before flowering the second and dying, although if it’s happy it won’t disappear as it makes plenty of seedlings. That said, as an insurance policy I would plant two years running as you’ll get flowering each year after.
