For the Blue Daze I Googled and found the following:

Culture
Evolvulus grows well in full sun in poor sandy soils that are well drained.

Light: Evolvulus does best in full sun, but can tolerate a little shade, especially at midday.
Moisture: Evolvulus needs a well drained soil, but also frequent watering. It cannot tolerate wet soils at all, and very rainy periods or overwatering will cause fungus problems and lead to premature death. Evolvulus needs very little water in winter, and the humidity should be low when the temperature is low.

Hardiness: USDA Zones 8 - 11. This is one plant that likes it hot! In areas that get frost, grow blue daze as an annual or in a container that can be brought inside. Some specimens of blue daze may survive light frosts, especially if they have been mulched.

And here's a link.

Not sure about the Palms but Google tells all. Try a search and see what you can learn that way.

Good luck and HTH
