There are many varieties of ti, for example, that are colorful - even solid colored ti (green, black, maroon) can set off the flowering plants nicely - and they are totally trouble-free. You can easily maintain them at any height you like. Ferns are low-growing and make good trouble-free ground covers even in full sun (bird's net fern (ekaha) can be very dramatic, laua'e will naturalize and fill in nicely, and its solid fronds can contrast in an interesting way with a more frilly fern such as palai or palapalai (maidenhair types).
