Position: Sun or light shade in any soil. Ours are in a sunny, dry spot under a tree so they don't get much moisture, but seem to thrive.
Flowers: June through July - really pretty flowers as you can see which are the colour of sunshine.
Dimensions: 90-120cm high and approximately 12cm wide - tall and skinny!
Habit: Biennial wild flower that looks great in amongst the smaller shrubs in the border.
Care: Leave it to do it's thing as it will self seed quite happily. Deadheading recommended - the old flowers are droopy and scruffy looking.
Pruning: not required - just reposition if they spring up where they're not wanted.
Propagation: By seed in spring.
Distribution: Eastern North America and naturalised in Europe. Wild flower so hedgerows, cracks in the pavement, the driveway down the road etc.
