Re: Iris savannarum

 

Patrick, I collected an iris from Dixie County, Florida that had no sign of flower stalks the first week of April, clearly blooming much later than savannarum in its native habitat. Here in Michigan it bloomed the first week of July, two or three weeks later than other Hexagonae (except possibly brevicaulis).

I donated some seed to SIGNA (14LA050 hexagona var. hexagona), basing my ID on the description of hexagona in Flora of North America (which seperates savannarum as a species, rather than a variety). I'm curious to know if anyone successfully grew any. My parent plant was eaten by rodents during the polar vortex, but I have one seedling.

Mark,

 

Thanks for that information.  I should have also asked….what county are these irises in?

 

I am involved in the Society for Louisiana Irises Species Preservation Project, and we have an irises obtained from Brevard County that is about to bloom.  It is growing in a large pot and the pot is sitting in pool with 3-4 inches of water.  There is only one bloom stalk, but it is five feet tall.  The donor gave it as I. savannarum, but some people consider all the East Coast irises in the Series Hexagonae to be I. hexagona.  I feel that I. savannarum in fact is closely related to what we call I. giganticaerulea, and that there are other Florida natives that in fact are I. hexagona.  They do not grow five feet tall and do not bloom as early.  I. giganticaerulea will often reach five feet in its native habitat, and it is an early  bloomer.

Patrick,

     They are over four feet tall, not far from five.  But, they are growing right at the edge of an Alligator pond...   I had not been monitoring the clump, but I would estimate it has been blooming a good ten days.

Mark,

 

Two questions.  How tall would you say these irises are?  And, on approximately what date would you say the first bloom occurred?
