Dear All, May 24, 2010
The Bugle (Ajuga reptans) on the lawn this year ranges in color from
deep blue (usual) to pink (unique to this year & localized).
The large Bumble Bees who work this plant seem to be color-blind but the
pink blossoms (if I remember correctly that the pink area had wood ash
applied this year) suggest that Bugle blossom color is dependent on
available Al; deep blue if high, pink if low.
Does anyone recall the term for plants with Al-conditional flower color
?
Yt, Dave Webster, Kentville
