The City Park Greenhouse serves as Denver Parks and Recreation's horticultural core by growing and distributing landscape bedding plants, shrubs and other ornamental plants for Denver park districts and other city agencies and facilities. We propagate approximately 250,000 annuals, perennials, shrubs and stock plants. The greenhouse produces flowers for 539-550 individual beds comprising 4.7 to 5.1 total acres of park land.

When are elaborate flower beds planted in Denver Parks?
Depending on weather, flower beds are planted in mid-May, once the threat of frost has passed. Elaborate flower displays are removed in early October.

Which parks include elaborate flowerbed displays?
Flower displays are planted throughout the city in different parks and parkways. Some of the largest and most popular flower displays include:

  • Alamo Placita Park
  • Cheesman Park
  • Civic Center Park
  • Cranmer Park
  • Garland Park
  • Inspiration Point Park
  • Washington Park

Can people pick flowers from the displays?
No- it is actually against city ordinance. It also ruins the display design that DPR Horticulturalists plan and cultivate a year advance and spend all summer taking care of. Please help us protect park resources so that everyone can enjoy this public amenity. If you witness someone removing flowers from a park, you can report it to 311 (720.913.1311) to dispatch a park ranger.
