There are few shrubs that fit into narrow spaces better than 'Dee Runk' boxwood (picture on the right). It is a better choice than currently popular cultivar 'Graham Blandy', which is seriously troubled by soil root rot diseases.
'Sky Pencil' Japanese holly (pictured above) exhibits a similar upright (fastigiate) form. Japanese holly demands a well-drained soil, and is very susceptible to several soil root rot diseases.
Both 'Dee Runk' boxwood and 'Sky Pencil' holly grow well in large landscape containers on home patios and along downtown urban streets in USDA zone 7-9. Expected height of 8-10 feet at maturity.
