[NAFEX] elderberries under black-walnuts

If someone was thinking of allelopathy here, the juglone exuded by the black
walnut may persist in the soil long enough to have an effect.  However,
elderberries are not affected by it.  Shade would have been the problem.  

I'll let someone else answer about how long they take to flower from seed,
but it seems to me it's less than 3 years.


111 degrees today.

I should have included this in my earlier observations:  A few yards off a
local
road, there was a big black-walnut removed 3 or 4 years ago.  This year a
Sambucus
canadensisr, growing w/in a few feet of the old stump, sent up a flower
cluster. 
The removed tree was stump-treated w/ herbicide, so there was no life in the
tree's
root system.  But, I got thinking, how long does it take an elderberry to
grow from
seed to flowering?  Did it start when the black-walnut was still there?
