Could any plants grow anywhere on Mars?

Seeing as Mars has a wide variation in temperature and ground water could any plants from Earth grow anywhere on the planet for even a short time? If not, how close are any plants to being able to grow there?

It would be difficult for plants that reproduce sexually to spread, but simple plants like algae, and even some colony organisms like lichens might find suitable conditions in isolated locations.

As for flowers and trees,  the conditions on Mars are extremely dehydrating. They would quickly freeze and lose their water, so even if something like an alpine flower or a pine tree were prepared by wintering it beforehand, exposure to the Martian surface conditions would do it in.

As for compatibility with the soil, there are no bacteria or fungi to cycle carbon or nitrogen, and peroxides/perchlorates in the soil would make it deadly for plant tissues.

It's not a garden, nor will it be one soon.
