Jim: Great information. The variegated tetrapanax root suckers green, so it would be a nightmare unless it could be grafted.

They are both in the ground and both have bloomed last year. Both were planted as established plants grown in the cool gh for a year, then planted out in our clay soils on a south facing slope near the house and given a light airy mulch of dry leaves, or pine straw this 'winter'. I think this is their 3rd year, but 2nd winter to bloom in the ground. Last winter got to -6 F and extended number of days below both 0 and more below freezing. Really pretty harsh for us lately. We had quite a bit of damage on some marginal plants, but not on these two. Last year we added I cretensis which is also looking pretty good, but may be too small to flower. Thanks Jane. Buds have emerged from their sheaths on I unguiculares recently, but no progress yet on I lazica. We expect it will bloom fine, too. Both plants came from Wildwood Gardens of Will Plotner in OR. http://wildwoodgardens.net/other_species_%20&_spec… Will hand carried plants to us during the AIS convention in spring '09. We tried these in other spots before, but seem to have found the microclimate they tolerate. Fingers remain crossed, but shows the truth behind believing in hardiness until you have killed it 3 x -or more. These are both in front of a lovely and also "tender' bed of Tetrapanax papyriferus. Wonderful plant. Just want a variegated version. Best Jim W. -- Dr. James W. Waddick 8871 NW Brostrom Rd. Kansas City Missouri 64152-2711 USA Ph. 816-746-1949 Zone 5 Record low -23F Summer 100F +
