Brassicaceae also known as cruciferae are more commonly known as mustards, rockets, cabbage. The name crucieferae derives from the four petals of the rocket flower.
They include brassica oleracea (broccoli, cabbage, cauliflower, etc.), brassica rapa (turnip, Chinese cabbage, etc.), brassica rapus (rapeseed, etc.), raphanus sativus (common radish), armoracia rusticana (horseradish) as well as a host of less common species.
Honey bees and solitary bees pollinate most brassicaceae. Tasty to folk, as any gardener is aware, they are also popular with many insects (including some pesky pests). However, if you allow some of the plants to go to flower and self-seed, they are also popular with butterflies.
