2017 Dahlia Show
Some gorgeous dahlias from the 2018 BSDS Show

If you are a beginning dahlia grower and want to enter your dahlias in our Novice division, arrive Saturday between 8:30 and 10:00 a.m. and a club member will help you to “stage” your blooms. Just bring one or more dahlia blooms in a bucket. Each stem should have a single bloom (remove any others) and at least the top pair of leaves; you can remove lower leaves. We have the vases and everything else you’ll need on-site at no cost. There is also no charge to enter.

If you just want to be a spectator, come during any of our opening hours to enjoy hundreds of amazing dahlias of all sizes, colors and forms. Don’t forget your camera! On Sunday, bring your own container and take home some of the hundreds of beautiful blooms we will give away at 2:00 p.m. on Sunday. Show participation and admission are FREE! A club meeting takes place at the end of the show on Sunday. All welcome.
