It is mid September and the garden is looking more tattered and aged than usual. The above picture shows the dried and burned grass in the sunny portion of the garden. The foreground freedom grass still looks quite green but it is really best seen from a distance. September is the month of natural decline as plants complete their life cycles. Days are getting noticeably shorter but this September has been very hot. Not hot if you live in Austin, TX but hot for New England where air conditioning is still not in every home. Until today, we have had no significant rainfall since mid-August. This garden and the gardener are dependent on well water. A well ties one a bit more closely to nature. Choices must be made regarding water usage. Shower the body or the garden? Drink a cool glass of water or quench the thirst of a garden full of plants? With hundreds of feet of borders, a vegetable garden and a week of vacation, Mother Nature has chosen to remind me of the necessity of water. Those thin, large leaved plants with shallow roots are the first to show the signs of water stress. Hydrangeas and astilbe are limp and crispy. I cringe when I look at the withered foliage in the garden but here and there in the garden there are a few pristine perennials. One small and rather insignificant perennial herb shows no sign of stress. You might think it is the wooly leaved lamb's ear or the gray foliaged yarrows but even those plants have turned limp or browned. The Queen of the Garden this September is the herb rue, Ruta graveolens. I have only one plant and it has gotten no attention during the dry spell. Its foliage is blue and smooth and just looking at this plant brings down the heat. It is cool to the eye. It is an interesting herb which is native to the Balkans where the climate is hot and dry. Rue has been used medicinally for centuries and was said to have been ingested by Leonardo Da Vinci and Michelangelo to improve their eyesight. It can also cause violent vomiting and gastric distress and the oils from this plant can blister the skin. It is also quite bitter. I will stick to using it in the garden. I have read that soft tip cuttings taken in the fall and stuck in moist sand will root during the winter. I may just have to increase my stock of this plant and give this a try. It would make a lovely border plant as it grows in an upright, rounded form. Rue has long been a symbol of bitterness and regret but I have no regrets in planting this cool beauty in the garden. In fact, I know I need a few more of them.
