Red Ace Hybrid Beet Seeds. The attractive red-veined leaves crowning this hybrid make tasty greens. Not to be outdone, the exceptionally sweet flesh of the round, deep red coloured root is delicious freshly cooked or pickled. Quick to mature, excellent heat and bolting resistance, a long harvest period and an ability to maintain their tender sweet tasting flesh when larger, all together make them Red Ace a prime candidate for the best all around beet.
