Landscape architects and horticultu

Landscape architects and horticulturists usually extend the
colonial period 64 years to 1840. By including the years from
1620 to 1840 we can tell a more complete story even though
the period isn’t historically correct.
There are several reasons for this. Garden design changed
little until about mid-point in the Greek Revival (12) period.
Then there was great change with the advent of Victorian
architecture and styles.
