Planting advice for bearded Iris, please.
I recently treated myself to a couple of bearded irises. I've grown dutch irises before but not these. I remember from an old GW programme that Monty said that the corms should be exposed to the sun.
I researched planting and care for them over the last week and it appears there are two types, with a corm, and rhizomatous. Some websites suggest that corms and rhizomes are the same while others state a difference though it seems that to me that there is a clear difference.
I've also read that in more northern climates (I live in Sheffield) those with corms shouldn't be exposed, although the last time it went below -5C here was in 2010.
So, I'm hoping someone with experience and knowledge of these plants will help me before I put them in the ground. They're going to be in an east-facing garden. The two varieties I bought are Germanica 'Black Dragon' and Germanica senlac.
I haven't opened the packaging yet but I'm eager to get them in the ground.
