Lavender today. It grows really well in urban locations, such as here in a busy shopping precinct. I’ve been looking at ways to grow new Lavender plants from old leggy ones.
Mounding is a suitable method for Lavender. Simply make a mound of easy-to-root-in soil, with the existing lavender plant shoots, just peeking through. In time the old branches will send down roots, into the mound and you’ll be able to cut off a while bunch of new small plants.
