As part of the RHS Level 3 course we have to learn about different garden design eras, one of which is medieval. Lambeth Palace, the London residence of the Archbishop of Canterbury, has an 11 acre site that has been cultivated since the 15th Century in medieval times. Unfortunately, though understandably, none of those elements remain. In place is an extravagant site with interesting plays on plantings. The gravel garden felt Mediterranean and has given me ideas for our own garden (I’ll always associate gravel like that with my first visit to East Ruston Old Vicarage). In particular, to my eye, the stand out features right now are some simple but beautiful experiments with grass.
