Broccoli that feels heavy to the touch is good, but if the bulb is too hard and the stalks are unusually wide and firm, the plant is too old. If the broccoli is leafy, then leaves that are tender, green and moist are fresher. Another thing to look for is whether the cut of the broccoli stalk is moist, if it is too dry then it has been harvested for a long time and is not fresh enough.
