ok thanks =) but what are the conditions that i should have for
the hydrangeas?
uhh.. not much.. the folks just chuck in the garden and it
grew.. they took a cutting and it grew.. and they took a cutting
from the cutting and it grew.. and on and on 
i read somewhere that the acidity of the soil causes the
different colours.. so i think the soil has different acidity where
the roots are, causing the strange multi-hue blooms
