How are cool weather crops related?
Many cool weather crops belong to the genus brassica in the mustard family, brassicaceae. The members of this genus are collectively
known as cruciferous vegetables. They
get this name from the Latin word Cruciferae which means “cross-bearing”. This is because their flowers consist of four
petals and resemble a cross.
Almost all parts of some species or other have been
developed for food, including the root (rutabaga, turnips), stems (kohlrabi),
leaves (cabbage, kale), flowers (cauliflower, broccoli, Brussel sprouts), and
seeds (many, including mustard seed, and oil-producing canola). Some forms with
white or purple foliage or flower heads are also sometimes grown for decoration
(ornamental cabbage and kale).
Brassica vegetables are very healthy. They contain chemical compounds known to help
aid DNA repair in cells, help reduce cancer risks, and also boost you immune
system. However, many people find that
brassica vegetables are bitter. It turns
out that there is actually a genetic basis for kids not wanting to eat their
Brussel sprouts. A dislike for cruciferous
vegetables can be due to the Brassica species containing a chemical similar to
phenylthiocarbamide (PTC), a chemical which is either bitter or tasteless depending
on one's genetic makeup.
Cruciferous vegetables are all cool weather plants that do
well in the spring and fall. Some ornamental
cabbage and kale varieties actually become more vibrant as the temperatures
grow cooler. If you would like to plant
a fall garden or cold frame these are the perfect veggies to add.
