In the Netherlands, the first horticultural college was founded in 1896 in Naaldwijk; the second horticultural college was founded in 1897 in Aalsmeer. In 1926, the first national professional qualification examinations in floristry were held in the Netherlands. The horticultural college in Aalsmeer celebrated its 75th anniversary in 1972 and in 1997 its 100th anniversary. Since 1926 is the horticultural college in Aalsmeer was called the ‘Rijks Middelbare Tuinbouw School’ (RTMS). The first professional floristry education started at the RMTS in 1968. The first professor in floristry at the horticultural college in Aalsmeer was Mr. Theo Boerma. In 1972 Theo Boerma started teaching professional evening courses for the floristry diploma: vakdiploma Bloemist-Winkelier. In 1980 Theo Boerma and his wife José Boerma founded the first privately owned floristry school; Boerma Instituut International Floral Design School in Aalsmeer. The floristry diploma was recognized by the Dutch government until 1996. When the borders of Europe opened, the diploma was no longer needed but professional training for Dutch and international students is still organised by the Boerma Instituut.
