Cultivars/Varieties
'Dissecta' - This is a cut-leaf form with more deeply divided leaflets than 'Laciniata'. It is a female form with red fruit and brilliant red fall color. It is difficult to distinguish from 'Laciniata' unless both are present together, plus the two forms are confused in the trade.
'Laciniata' - This is a fine-textured form cultivated in large-scale naturalistic gardens. The leaflets are divided to create this airy feel, though the dissection is supposedly less extreme than 'Dissecta'. They are confused in the trade, though fairly common at specialty nurseries.
