Dear All,        May 26, 2007
Further to my post of May 2, 2006 (below), I checked today and there are 
now 21 leaves.

    On a related note, several weeks ago I noticed an interesting 
association between Yellow Birch and Trout Lily. Perhaps by chance, 
perhaps by strong root competition, there were no trees of any size 
within ~25' of the Birch and there was a dense carpet of Trout Lily over 
this circular area of ~50' diameter with the Birch in the center; no 
Trout Lily in sight beyond this disk.

    On July 16, 2003 I dug up a few Erythronium americanum bulbs for a 
friend, planted 3 (4?) of the smaller ones in our garden and marked the 
location with a stake, so they wouldn't get dug up by accident. None 
have flowered so far.

    In the wild, the bulbs are quite deep (10-15 cm) and I wondered how 
a seed that germinated near the surface would manage to generate a bulb 
that deep in the ground.

    This year there are six isolated leaves (& a possible 7th) and they 
appear to have wandered several dm from the initial planting site. An 
obscure phrase in Fernald explains all; "Bulb deep-seated, sending out 
elongate propagating shoots;".

Yours truly, Dave Webster, Kentville
