Lilacs and soil PH

[Donola]

I remember reading once that The colour of Lilac flowers , were directly asscoiated with the PH value of the soil they were growing in .... since reading this article , I have not come across any similar mention of this relationship.
can anyone verify this or Nonense this , which ever is appropiate

I heard something similar about Hydrangeas and aluminium content of the soil. Blue = aluminium.

I've been in horticulture, one way or another, nearly all my working life, but I have never heard, or have any reason to believe this.

The colour of a Lilac flower is determined by its variety or species, not be the soil it grows in, however, that is not to say that a low Ph for example, would not deepen the colour of a particular variety.

In order to see if this were to happen, you would have to either grow two 'cloned' plants side-by-side in different soils; or cut flowers from one plant and take to plants in other soils, again of exactly the same variety.

The most obvious plant that does change with a differing Ph value is of course Hydrangea. Perhaps you were confusing Lilac with that?

Thanks .... Yeh, probably me getting confused, which would explain Why I havn't seen any reference to lilacs since.
