Enjoyed a huge carpet of nasturtiums at my allotment last summer, nestled at the base of my sweetcorn plants (I even tried eating some nasturtium leaves & flowers). These are a darker red colour than the variety I am used to seeing & they were admired by many. I will sow them again during 2022.
Not as dRk as I presumed them to be ok though to brighten a dull corner..beware slugs and earwigs love them.. as fast as they flower the leaves are devoured
