The Most Productive Dahlias (and Best Tuber Makers)

Two kinds of productivity matter. Bloom productivity fills a market table; tuber productivity fills next year's bed and your trade pile. The varieties here are documented for one or both. Sellers rarely tell you a flower is a weak tuber maker, so where a grower has said it plainly, we pass it along.

If you are trying to multiply stock of an expensive variety, lean toward the ones noted for generous, easy-to-divide clumps.
