I think you have misinterpreted the information on Schreiner's website. EML doesn't mean a plant is a rebloomer. It just means the plant blooms over a relatively long period in the spring. For example, an EML tall bearded iris in my garden would start blooming around the first week of May and still be in bloom towards the end of the month. To do that, a TB would need a high bud count, a slow sequence of bloom (very few flowers open at any given time), or a combination of the two.
