Veratrum planting depth

[gote]

Gote, I bought Veratrum maackii locally some years ago and I have to say your mention of it here and now, is the only reference I've ever seen (not that I've looked). Mine is brown even in the foliage and honestly, is one of my less exciting plants.

I found it a quite nice meadow plant in Utsukushi no Hara near Matsumoto. Unfortunately I have no scans. It is not an exciting plant.  I later bought one and it turned out green and does not do very well. It seems that it is variable in colour and stature.

Mark I am sure it will find it's optimum depth by itself.  A friend down the road is growing Veratrum nigrum and has a nice clump, this year she was going to split it up but gave up trying as the bulbs had gone much deeper than she had originally planted them.

Once well established, the larger veratrums such as niger and album need three strong men with large spades, and probably a small bulldozer with digger attachment, to lift them.

That gives me three men's strength Lesley 
(But I have light soil - and use a fork not spade)
But I do agree.  They are awkward to move even if not as awkward as Gentiana lutea
