Hi Paul,
Just to add a bit to your comments; it is true that adding Aluminum =
Sulphate to soil will increase soil acidity (decrease soil pH) and =
induce blue coloration in Hydrangia flowers.
But as I am sure would have been documented by Evelyn Hutchinson =
(The Biogeochemistry of Aluminum, Biological Reviews ~1950) elevated =
Al+++ ion activity causes the blue coloration, not elevated H+ activity. =
Drawing on memory nearly 30 years faint; H+ and Al+++ ions have a =
yin/yang relationship in natural soils. Increasing soil acidity by e.g. =
adding elemental Sulphur (on a weight basis 6 times as effective as =
Aluminum Sulphate) also leads to an increase in Al+++ activity because =
H+ ions displace adsorbed Al+++ from soil colloids. Conversely, adding =
Al+++ ions (e.g. as Aluminum Sulphate) increases soil acidity by =
displacing adsorbed H+.

Hi All
The change from blue to white flowers is often as a result of the ph =
of the soil. A low ph produces blue flowers - a high ph white flowers. =
Hydrangea are especially sensitive in this way so perhaps Blue Flags =
also. Local garden centers sell aluminum sulphate for to keep hydrangea =
blue - it might work with Flags.
May your flags always be blue=20
