I obtained seed from the SRGC exchange and have raised a couple of nice seedlings but can find no information about this species other than it is an accepted name. Does it need similar treatment to I. delavayi etc or is it one of the more unusual species like arguta and olgae ? I am still hunting for seed of I. emodi - does anyone grow it ? We had it at Kerrachar (Archibald seed) but did not maintain succession.
