Arisaema missing from the garden? Go and dig!

[Véronique Macrelle]

 It's a lovely story:
A few years ago I decided to plant my tuber of Arisaema lichiangense (or candissimum, finally maybe, I don't really know). It was a beautiful plant that for 2 or 3 years really appreciated being in the ground, grew, flowered (at last!).
Then a sudden frost, damp, slugs or rodents got the better of it: it hasn't come back, and it's been
It hasn't come back for 2 years (or more?). :'(


I learnt from Pascal Bruggeman's comments (lots to learn!) that the sessile bulbils that detached from the mature tuber were often buried too deep to emerge and that it was better to repot them less deeply.


So I decided to dig and stir up the soil where this beautiful Ariaema used to be - in any case, I'd have to reclaim the space to put something else in...
 And victory! I found 2 small tubers 1.5 cm in diameter that had been waiting for better conditions for over 2 years!


So if, like me, you've lost some sessile bulbous Arisaema in your garden, go and have a look in depth, you never know.


My question now: what is the optimum depth for a 1 cm Arisaema tuber?

I have a similar story.

I had a patch of bamboo that was spreading too far, so I hired someone to dig it out with a backhoe.  I was surprised when an arisaema came up and bloomed where the bamboo had been.  When I checked my records, I found it had last grown twelve years previously, before it was overgrown by the bamboo.

12 years is a long time!
