The white one with green edges has been out in full hawaiian sun for a week and is really starting to die. the grasslike plant is also browning but not to the same level. If I know their names I can hopefully save them.
The first one is definitely a Deiffenbachia; can't speak to the second one. Dieffs in their natural habitat (here in Ecuador) grow in at least partial if not full shade - if yours has been in full tropical sun, it's going to lose the leaves that got burnt. Keep it in the shade and water it well, and it will recover. Lovely variegation on yours - normally Dieffs have more green to them. The abundance of white tissue on the leaves of your plant makes it more susceptible to sunburn than most other Dieffenbachia cultivars. You can cut off the crispy-fried leaves if you wish; it won't hurt the plant - only be careful of the sap, which can be a contact irritant for some people.
i agree with dieffenbachia. there are many varieties and i'm not too familiar with the different types to give anything more than a general genus id... the other one is more likely chamaedorea and specifically the 'elegans' species. aka parlor palm. it's more common as a houseplant...although, being in hawaii, it may just be the dypsis (previously chrysalidocarpus) aka areca palm.
#2 does looks like an Areca palm with it's thick stems. It's a great palm, looks good and is easy to care for.
Well I thank you both for your replies, I have since moved my dieffenbachia out of the direct light. Attached is 2 more plants that I have on my lanai but they currently do not get direct sun all day. They seem to be doing better. Can you ID them?
I think the first plant in the first picture may be D.picta 'Camilla', not sure, but someone else is bound to correct me if I'm wrong! They have these in the U.K. I nearly bought one the other day but I like the variety you have better than the more green D.amoena (at least I assume thats the other type they had) but they didn't have any little ones in that variety.
Sansevieria trifasciata will send out white flowers (if it's happy) on long stems and they have a fantastic scent!
Wow I am really impressed with the replies and so quick! Both of my questions were answered within hours! Thank you so much to everyone who helped me.
Yup! That's right! Sanseveria can bear spikes of subtle flowers. You can propagate them easily through division or leaf cuttings. Be careful to not to overwater. My sanseveria before turns mushy and died due to overwatering.
