Kiwifruit and Hardy Kiwi, HYG-1426-93 here is a good site on kiwi, and the cordyline, not sure what you have, there are at least 15 types, but with all seedlings it is best to give them filtered light and slowly acclimate them to full sun over a period of time 2 weeks to 2 months, your plants will tell you if its to much?
