Will Dracaena Marginata take a frost?

How cold will this plant take it? At what degree will it cause damage?

They are quite tropical. I would not expose mine to temps below 35.0 F.

If the conditions are right and the temperature falls fast enough, chill injury, which is different than freeze injury, can occur at temps as high as 45-50*. Many tropical and subtropical plants will tolerate temperatures below 55*, but they won't like it. Generally, plants that grow in areas where the temperatures naturally don't drop below 55-60* grow there for a reason. These plants' metabolisms and their ability to carry on photosynthesis efficiently are often considerably impaired by temperatures below 55-60*.

How cold a plant will 'take it' before it incurs damage is sort of a subjective question. Technically, any time a plant is using more energy than it is producing, it is in decline, and will die unless the trend is reversed, so almost all houseplants subjected to temperatures below 55-60* are in decline.
