Celebrate the changing seasons with Dahlia Days! Thousands of dahlias are planted in the Ashton Gardens every year, ranging in size, color, and texture. Some formal and some flashy, these vibrant flowers come in every color imaginable and are some of our horticulturists’ favorites. Find the lively exhibit at the Dahlia Display Garden, take a class taught by dahlia experts, or see if you can find them placed randomly throughout the Ashton Gardens. No matter what, you’ll enjoy a pleasant visit to Ashton Gardens during one of the most beautiful times of the year.
Special thanks to the Utah Dahlia Society for helping present a display of cut dahlias. Join us in the Visitor Center on September 19 and 20 to see this display, which will showcase many popular and unusual varieties of dahlias.
New this year – do not miss the Cut Dahlia Sale on September 22 where you can take home beautiful cut flowers from the gardens.
