Swan Island Dahlias
Swan Island Dahlias

Swan Island Dahlias produces the largest full-color dahlia catalog in the industry. They hybridize their own new varieties, planting over 15,000 seedlings each year. From those original seedlings, it takes about 4 to 5 years to introduce a new seedling for sale. Each season they introduce anywhere from 5 to 15 new varieties which are featured in our catalog and at our farm. They grow over 370 varieties on almost 40 acres that are open to the public during the blooming season and host the largest dahlia festival in the United States featuring over 400 dahlia arrangements during the six-day festival. They are very proud of the farming tradition their family brings to the business they’ve owned and operated for three generations. They are dedicated to bringing the best and highest quality dahlias the world has to offer now and in future generations to come.

Crazy 4 Dahlias is owned and operated by John Spangenberg. I am located in Damascus, Maryland and I have been growing and exhibiting dahlias for 18 years. I am a member of the National Capital Dahlia Society. I am a senior judge and am on the Classification Committee in the American Dahlia Society. I am also the director for the Mid Atlantic Trial Garden.

We grow about 800 dahlias each year. we grow 95% show dahlias. Our location in Maryland is not the most hospitable place to grow dahlias. There are many varieties that do not preform in out hot and humid summer. Our focus is to develop and grow dahlias that will preform at show in a hotter climate. We feel that if they do well here they should excel almost every where else. Every year we try out many new introduction to see how well they do. If they don’t make the cut they are thrown out to make room for ones that do.
