This week on Backyard Farmer focus on spring rose care and conifer cones This week on Backyard Farmer we’ll focus on spring rose care and interesting cone development on conifers.

Exploring patterns in the evolution of seed plant reproductive morphology within a functional context offers a framework in which to identify and evaluate factors that potentially drive reproductive ...

One of the simplest examples of how plants adapt to ensure that their species survives is found in pine cones. Evergreen trees that produce cones are called conifers. There are more than 600 species ...
