We sell only top quality 1st grade A single division tubers (price is per tuber), fully guaranteed to grow, be true to name, and free from disease. We replant our fields each spring from the same stock we are selling. Guarantee covers the current season's orders, and we are not responsible for customer negligence, weather conditions, rodent damage, winter storage, or performance of plants in following seasons. Each tuber will produce a full size plant with beautiful flowers late summer through frost. All dahlias should emerge from the soil within 3-5 weeks after planting. For any dahlia that fails to emerge after 5 weeks, please dig it up and contact us immediately for further instructions, no later than August 1st of the same growing season. Do not dispose of any tubers or plants until you have contacted us. Any other concerns regarding your growing dahlias must be reported by October 1st of the same growing season. If you start your dahlias early or grow in containers, we do not recommend using any type of soil with pre-added fertilizers or compost which most bagged soils contain. Our customers are reporting fatal results when these enriched products are used to start their dahlias and doing so may void our guarantee. We reserve the right to request the return of any failed dahlia(s), or photos of them, before replacements will be made. Replacements of the same variety will be sent the following spring at no charge, US orders only.

MAY I BRING MY DOG TO YOUR FARM? We receive many calls from our puppy parents wondering if it is ok to bring their dogs to our farm. Our farm is dog friendly - except during our festival. We do not allow dogs into the indoor display rooms (of course with the exception of "Service Animals") and would prefer you do not bring your dogs/animals during the six days of our festival. This is for the safety of all attending. We want everyone to enjoy the celebration. Thank you for your understanding & cooperation!

We offer fresh cut flowers approx. mid-July through frost (usually the first week in October) each year, for local pick up, and mid-July through September for shipping. To order cut flowers please call us at (503) 266-7711 (We do not offer U-picks) If you are not specific on colors we have a great selection at our fresh cut self-serve stand for you to just drop by and purchase. We are closed Wednesdays during August & September. 

Please call for details or see cutflower page for more information.
BLOOM TIMES: In general the larger the bloom the longer the time for them to get blooming. 8-12" blooms will take approximately 120 days from planting to bloom time. Low growing and dwarf dahlias will take approximately 75 days from planting to bloom time. All others will be blooming approximately 90 days after planting. Once they begin to bloom they will continue to bloom through frost. However, this time frame will vary, depending on weather, water, and fertilizer given. 

SUBSTITUTES: If something should be unavailable we will do our absolute best at making sure you are notified ahead of time. Please let us know when placing your order if something is unavailable would you prefer a refund or substitution? Make sure this is noted on your order at the time it is placed as we are unable to call or contact you later. We only substitute with a similar variety of dahlia, same or greater value. Thank you!
