News & Events


The Castle Rock Farmers Market
Will run on Saturday Mornings from July 11th through
Oct 3rd
from 8:00 am to 12:00 (noon)
The Castle Rock Farmers Market is located in the parking lot on the corner of 3rd and Elbert St.
The Castle Rock FarmersMarket provides Douglas County residents with a local market where they can purchase fresh fruits, vegetables and other horticultural products. The Castle Rock Farmers Market is unique in that it was started by a Master Gardener as a community service project and the board continues to embrace that idealogy by requiring that 80% of vendor produce be Colorado grown and specialty vendors should be connected to the Horticulture/Agriculture Industry.

Would you like to learn more about the beautiful plants that grow in nature? Take a Native Plant Master course and get to know the plants of Colorado...

Douglas County, Colorado has a wealth of native plants, colorful wildflowers, grasses, shrubs and trees, which are well adapted to our variable climate, soils, temperatures and elevations. Native plants are great for landscaping because of their adaptability.

What is the Native Plant Master (NPM) Program? The NPM program, started in Jefferson County, has grown statewide to help foster an appreciation of native Colorado plants. Participants learn to identify native plants through participation in a NPM course.

Why take a Native Plant Master offering?

  • Learn plant identification skills by using a botanical key and become comfortable with plant families and scientific names
  • Find out which native plants can save water in your landscape and which are invasive aliens.
  • Apply what you learn in a course in the optional NPM volunteer track option, which will enable you to teach others about native plants. 

Can anyone take a NPM course or class? NPM offerings are open to anyone 16 years or older on a space available, fee paid basis. Course fee is $90.

In Douglas County, we are offering TWO NPM courses at two distinctly varied state parks:
Castlewood Canyon State Park : May 27, 29, June 1
Roxborough State Park: June 2, 6, 9

After registering for a Douglas County NPM course, you will be able to enroll in a special basic botany class, where you will be introduced to botanical terminology and nomenclature, preparing you for your course. This class is provided free of charge to course enrollees.

Where can you enroll?
Applications (due May 15) and course details can be found on this website. To get all the information click HERE
