Not having a garden, I have a sort of gazebo on my parking lot in
front of
the office (my husband and I are self-employed) and I have loads of
pots
with all kinds of stuff growing.

I put a hydrangea in a large round terracotta pot and later on,
planted two small
lettuce heads next to it. The other lettuce heads I had planted in two
other
pots and in four window-boxes on my mini-balcony at home.

The lettuce heads in the hydrangea pot are growing like crazy, much
more
than the others which were planted a fortnight before, but I'm scared
to
eat them because hydrangeas are poisonous and I'm worried the lettuce
might have sucked up thy cyanide through the roots...

Any experiences in this respect?

Thanks!

Melanie
