I have Iris siberica flowering now in SW London in normal ( in fact

I have had mine growing as a marginal plant in my pond for decades,
roots just above water level. I split one clump up and planted some on
our S. facing front garden where the soil is well drained due to
builders sand being incorporated (by the builder!), they died out over a
couple of years. If your garden is heavy loam then that may explain why
they have done OK but I have always found they liked a damp spot.




Thanks, Bob, that's great! It does sound as if I've been lucky with
mine so far. I'll risk it no further, but get them into a boggy pot for
now, pending the building of my new bog garden. Too late to do it
tonight, but rain is forecast and I've already seen a flash of
lightening, so they should be happy tonight! :~).
