I went out to do some Fall clean up today and noticed one of my seed grown I. suaveolens var. rubromarginata had send up multiple flowers though with some freeze damage.  So now I am wondering if this is unusual for this species to rebloom in the Fall.  A couple of its sibs did rebloom this past Spring and this one may have as well.  This one though is a decent (for the species) dusky purple with red-purple tinged foliage that persists into the Summer more so than the others did.  The sibs also had dull yellow flowers.  They do need to be separated as they have intermingled some in their mat-forming habit so my recollection of which one did what is cloudy.  But this is the only that rebloomed now.  I don't generally water or fertilize much especially since this one is in a raised bed with he Arils and Arilbreds and it has been rather dry here lately.  Taking those factors into consideration and the mutiple inflorescences it must be the real thing and not a fluke.

Any thoughts from the Rebloom Gurus on this ocurrance or from others who have grown this species?  I know that the regular I. suaveolens (and decendants) can give reblooming seedlings, but haven't heard of many of the pure species doing so let alone here in Zone 5 and in the Fall no less.
