Avoid palms that produces alot of seeds and germnates quickly. Any clumpy palm that spreads to rapidly. Other thoose tips good luck!

There are several species that are escaping home gardens and wreaking havoc with the natural ecosystems-give these baddies a wide berth.

The link below is not a comprehensive list, doesn't include banana poka (passifolia tarminiana)for example. You can also go to www.hear.org for information about invasives.

OK, now on to the fun stuff!

I wish i had never planted...psittacorum in my garden. Looks terrible most of the time and is really hard to contain or eradicate.

Congratulations on your new project! Sounds like you will be having fun.

Don't plant wedelia !

Thanks for the responses and resources! While I was aware of some of the plants named as invasive, there were also some surprises, such as Clusia rosea and mauirose's mention of psittacorum -- never would have known it was so maddeningly prolific. I thought they were planted in masses for effect. : D

Please continue!

Not Hawaii, but similar climate. Busy Lizzy: Impatiens walleriana. The New Guinea type is OK. Very pretty but self seeds like mad. Black-eyed Susan - likewise. GRASS! Keep your grass areas down to a minimum or you will spend all your time with a lawn-mower! And be prepared to use a herbicide. Whatever you do it will come up everywhere! Big bushy plants that shade it out are best. Good luck!

Golden pothos. Once they escape cultivation, they start to blanket and crawl on trees and the forest floors.

Impatiens walleriana never have reseeded for me, and I tried to germinate them once from buying seeds I got not even one sprout.

Areca palms, what a pain to maintain!

Blue Agave! Its comming up everywhere

Cashew tree; while it grew fast and produced nuts in about 3 years, it was impossible to harvest and prepare---it produces a harsh acid-like substance that will take your skin off until it is 'prepped' which means exceptionally high heat and other "not goin' to happen outside of big industry" requirements.

Heliconia. They take over and just keep going. I've been trying to dig them out ever since. Most of the gingers would probably be the same way, too.

Running bamboo is bad but the clumping varieties are good.

We have a passion fruit vine which is all over the place but it at least produces lots of fruit. If you want a vigorous climbing vine, then that's a good choice.
