Taxonomy & Evolution
A new study shows how differences in flower traits, pollinators preferences and other reproductive barriers help keep two closely related plant species separate, even though they can still produce healthy hybrid offspring.
Cells, Genes & Molecules
The common weed *Sonchus asper* may actually contain several distinct evolutionary groups that can be revealed by studying both its traits and DNA.
Taxonomy & Evolution
Seeds kept in storage for years turned out different from fresh ones taken from the same wild populations, showing why seed backups are so useful.

Ecosystems
A garden plant called Kalanchoe × houghtonii is spreading along Mediterranean coasts and may be pushing out native plants that normally grow there.
Meeting Plant Scientists
Botany One interviews Christopher Levine, a researcher working on the effects of light on plant production in controlled environments.
Close Encounters
Sorghum plants can sense nearby plants through chemicals in the soil water, and this makes them slow their growth, which helps explain why planting crops close together doesn’t always increase yields.

Cells, Genes & Molecules
Scientists discovered that modern roses’ ability to flower repeatedly comes from a single genetic mutation in Chinese wild roses, and by tracing their family tree, they showed how hybridization with a few wild species created the roses we know today.
