Could plants spread their seed to other planets?

Assume a plant was engineered to cope with a wide range of different environments, and to have seeds that were capable of traveling through and surviving both the depths of space and re-entry into atmosphere. Given this assumption then you can see these plants would slowly (much slower than light speed of course) spread throughout the galaxy.

The problem though is gravity wells, how would the planets get their seeds into orbit with sufficient escape velocity to reach other planets or better yet other solar systems? Is it even possible for a purely biological process unguided by intelligence (other than that which designed the planets in the first place) to do this?
