Simply set a global in your (:plant ...:) markup and then check the value
of that global before you include the garden map.  If you are using
(:include ...:) to include your map then the global you will set will be in
$FmtPV so that you have access to a page variable.  Don't forget your
"global" declaration of the variable at the top of the function and see
http://www.pmwiki.org/wiki/PmWiki/OtherVariables to see some special notes
on quoting for $FmtPV.

(You may have to change the 2nd argument to the Markup() function of your
(:plant ... :) markup in order to get it early enough in the process to
work.  Setting $EnableDiag=1 in config.php and then using ?action=ruleset
will enable you to see exactly what order the rules will fire.)
