Dutch landscape and garden architect Mien Ruys (1904–1999) was born into a horticultural family in Overijssel, where her father owned an internationally renowned plant nursery. Her immersion in planting and gardens from a young age contributed to a lifelong passion. Ruys received formal education as a garden designer and became actively involved in the modernist movement, in particular its unifying philosophy of good design for all. Along with names such as Piet Oudolf, she is considered a pioneer in the New Perennial Movement. This issue of Pleasant Place is dedicated to her legacy, with extensive biographical information, garden designs, personal accounts, and more.
