The brassica family, also known as the mustard or cruciferous family, is an economically important group of dicotyledonous plants that probably makes up a part of your everyday diet.
Family members are generally small herbaceous plants but there are some shrubby varieties and even a few vines as well.
Bisexual, radially symmetrical flowers are often bright yellow, though they’re sometimes light yellow, purple, or white. They’re usually arranged in a racemous inflorescence, with a few species that have individual separate flowers.
Pollinated flowers become seed pods that vary greatly in size and shape between species.
Stalks with flowers and seed pods have a distinctive look that, along with the flower anatomy, can make many family members relatively easy to spot.
Flowers, Fruits & Leaves
Sepals: 4 sepals.
Petals: 4 petals.
Male: 4 tall stamens, 2 short.
Female: 1 pistil
Fruit: Seed pods (called siliques) are situated around the stem radially. Though they come in all shapes and sizes, they generally all split to drop the seeds.
Seeds: Usually tiny and round.
Leaves: Simple alternate leaves with or without a petiole.
Wild mustard Brassica oleracea is a single species that is responsible for a range of cultivars including kale, broccoli, cauliflower, brussel sprouts, cabbage and many others. Roman broccoli is such a cultivar that has tightly bundled inflorescences that make a very interesting fractal spiral effect.
The Brassica genus is home to other culinary favourites such as various forms of mustard, turnips and canola.
There are countless species of colonising weeds in the family that can collectively be called “mustard weeds”. These are edible and tend to have a spicy wasabi-like spicy kick that lingers for minutes, especially older leaves.
Members of this family are safe to eat and generally have a distinctive broccoli taste, sometimes with a side of mustard heat which can be almost unbearable in some species.
