SPEC:CULT: Iris reichenbachii

<< Does anyone know what the growing requirements for I. reichenbachii are?  

According to the scant cultural information in the current species 
uber-resource, Species Irises, their Identification and Cultivation (Cambridge
, 1997), the species is native to Serbia to Macedonia to North-East Greece. 
This is considerably warmer than your zone. 

It further says "Should be grown in light, rich, well drained soil. This is 
another species that a seems to require quite frequent tranplantation. 
Reputed to be rather suscepticble to fungal and bacterial infection." p. 49. 
Apparently there is a known natural tetraploid clone. p. 50.    

Dykes (Handbook of Garden Irises, p.198) notes the need for frequent 
transplantation and notes the need for "plenty of lime rubble." In Dykes on 
Iriseses p. 28 he notes the need for "stong loam and plenty of lime."

Koehlein, (Iris, p.194) whom one must take with a large grain of salt on all 
things but who sometimes clarifies the words of others, says of the yellow 
form, "blooms freely is a stong grower, and is not tender." He was writing of 
hardiness in Germany. And "Its tremendous increase, with rhizome growing over 
rhizome makes it necessary to divide and transplant clumps every 3 years. Its 
robustness makes it a good companion to cushion plants." He notes that it is 
not, however, much to look at. 

I could move on through the rest of the bookshelf, but this should give you 
enough to mull initially.
