Codiaeum variegatum, Croton, differences in cold hardiness of cultivars
Posted 20 March 2012 - 05:59 AM
In the Tropical Stream Garden here at Leu Gardens we have planted out several dozen cultivars of Croton, Codiaeum variegatum. Until the past 2 winters I had never really noticed much difference in cold hardiness between cultivars. But this became evident following the 2 long winters.
The crotons grow in mostly bright shade so they do not get frost. Also, the area they grow in is warmer so probably didn't see much below 30-31F. Here are some general observations on how some of the cultvars tolerated the cold.
Anyone else have observations on cold hardiness differences in croton cultivars ??
TENDER- these were killed
SEMI TENDER- these suffered moderate to severe damage
'AFD #5' ('Fantasy')
HARDIER- little or no damage
'Appendiculatum' ('Mother and Daughter')
'Aureo-maculata' ('Gold Dust')

I would agree with most of your findings but there are a few inconsistencies. I had 26F in the open garden in January 2010 with 28-30F likely under canopy. Nestor and Piecrust survived here with Nestor not even completely defoliating. These are very old cultivars and typically have better genetics than more recently introduced clones.
By the way, Appendiculatum and Mother and Daughter are not the same plant. Appendiculatum has samller leaves that are completely green including the undersides. M & D has larger leaves and some dark red/maroon color on the undersides.

And with 'Sloppy Painter', that makes sense, I always thought they looked the same.
