Send a petunia to let someone know that you have anger and resentment. A marigold's size determines the message. A large flower indicates jealousy while a small flower means never despair. Watch out for sunflowers, they signify haughtiness and false appearances. Other symbolic plants include cactus that means warmth.
Some herbs send meanings as well.
A pasta dinner with pesto may be inviting to some but not on Valentines Day. Basil signifies hatred and is probably not what some would consider appropriate for the day. The American Heart Association wants you to think of your physical heart as well. Statistics tell us that more Americans die each year from heart disease than from cancer. Unlike cancer, you can take an active role in preventing this disease.
