Should Buddhists only cultivate native plants?

Reading various threads here, I know that plants are not considered to be sentient beings in Buddhism. But I still can't help wondering whether Buddhists create bad karma if they cultivate non-native plants. By 'cultivate' I mean for example *planting* a palm tree in a temperate climate (with large temperature changes over a year) or a giant sequoia anywhere but in the Sierra Nevada mountains in California. (I do *not* mean caring for plants that have been planted by others before me.)
