50 Flowers that Start with "M"

Below is our expansive gallery and directory featuring flowers that start with “M”. For example, an interesting plant in this list is the Monkshood, also known by other common names such as Wolfsbane, Friar’s Cap and Blue Rocket. Don’t let its beauty fool you.

Monkshood is one of the deadliest plants in existence. Every part of this beautiful flower — especially its roots and seeds) is poisonous. It’s also called Wolfsbane because the juice from its roots were used as arrow poison during wars or as poison bait for hunting wolves.

Monkshood is so deadly that it’s even illegal in some countries to grow this plant without a permit. Take extra precaution to avoid skin or oral contact with its juice. Best to wear gloves if you have to work with it and make sure you cover up any open wounds or skin grazes.

Avoid contact with pets and small children. Below is our entire gallery showcasing these flowers.
