Hampshire, United Kingdom
I have a very tall mallow but don't know if it is annual, perennial, shrub or tree. It is as tall as me (over 5 ft) and has lots of long arching stems, the flowers are pale pink and bloom all along the stems.
Should I cut it back with other border plants as I don't want ti straggley next year.
How much do I prune off - cut it right down as I do with a lot of my perennials - or what?
