Look for Parsley Hawthorns along suburban streets as well as in the woods. Being hawthorns, they like moisture and somewhat acidic soil. Most of the landscaping trees will be relatively small (under 15' tall) but in the wild under good conditions they will grow to 20' tall.

The unique beauty of Parsley Hawthorn trees have lead to it being taken out of the wild and added to many landscapes. The mottled, flakey gray-brown bark makes it an interesting specimen during its leafless winter months. Come early spring it covers itself in a thick blanket of white flowers...which have a rather unpleasant smell to many people. At the same time the tree's parsley-shaped leaves appear. Soon after the flowers disappear numerous small, green fruit show up. By November these fruit will have turned bright red and most of the leaves will be dropping. Still small, these fruit a rarely bigger than peas but have a wonderful, sweet flavor.

The ripe fruit can be eaten raw, dried, or made into jelly. The raw and dried fruit can be made into a very beneficial tea. The flowers and leaves can also be used to make tea.

Western science has found a number of medicinal properties with Parsley Hawthorn (and also many of the other hawthorns). Extracts of the flower, leaves, and fruit have found to help strengthen the heart and lower high blood pressure. The blood pressure reduction comes from some beta-blocking effects of compounds in this plant. That being said, I recommend following your M.D.'s orders and prescriptions in reducing blood pressure. The concentration of active beta-blocking agents in Parsley Hawthorn can vary quite a bit from plant to plant so getting the correct dosage is very difficult. Also, beta-blockers are known to trigger asthma attacks in those who suffer from asthma.

One of the potential good side effects of beta-blockers is they can reduce the "fight-or-flight" reactions in humans. Many concert musicians and actors/actresses who suffer from stage fright (a common fight/fight situation) request beta-blockers from their M.D.s to help counter the physiological effects of stage fright. Hawthorn tea should have a similar effect but note that hawthorn tea is diuretic (makes you have to pee), so plan accordingly if you are going to drink some before heading up onto stage!
