Is it a weed or a wonderful plant??
Hampshire, United Kingdom
Can anyone help for a couple of years in my front garden I have a bed of my Dad's old roses (30 years old now and been moved about 7 times!) but of course with old roses they are getting a bit knarly at the bottom. One year this plant seeded itself and its been great - it covers the bottom of the roses in loads of purple flowers on quite tall spikes with the roses sticking out at the top - but everyone is asking what it is and I dont have a clue any ideas??
