This species-clustering was corroborated by a perMANOVA that detected a significant difference between the two Aconitum species (F 1,16 = 6.107, p <0.001). The separation between the two Aconitum species was further investigated by partial least squares discriminant analysis (PLS-DA) (Fig. 3 B), a supervised method that explains maximum separation among defined classes of samples. The 5 most influential candidates for each species were tentatively identified as known alkaloids by matching the obtained molecular formulae with the DNP database (Table 3). All of them but one have been reported in the Aconitum and / or Delphinium genera (Ranunculaceae family). It is native to Afghanistan, Alabama, Alaska, Albania, Alberta and other regions. In the garden it prefers partial shade and clay and loam soil. In UK gardens it is fully hardy throughout the UK (RHS H7). Suggested uses include cottage and informal garden, wildlife gardens and architectural. It tolerates soil of any pH, moist but well-drained, well-drained conditions and north-facing, west-facing and east-facing aspects.
