were there olive trees in the garden of gethsemane
Gethsemane A study conducted by the National Research Council of Italy in 2012 found that several olive trees in the garden are amongst the oldest known to science.[11] Dates of 1092, 1166 and 1198 AD were obtained by carbon dating from older parts of the trunks of three trees.[11] DNA tests show that the trees were originally planted from the same parent plant.[11] This could indicate attempt to keep the lineage of an older species intact.[12][13] Then again the three trees tested could have been sprouts reviving from the older roots. "The results of tests on trees in the Garden of Gethsemane have not settled the question of whether the gnarled trees are the very same which sheltered Jesus because olive trees can grow back from roots after being cut down", researchers said.[13]
Ailanthus altissima In China, the tree of heaven has a long and rich history. It was mentioned in the oldest extant Chinese dictionary and listed in countless Chinese medical texts for its purported ability to cure ailments ranging from mental illness to baldness. The roots, leaves and bark are still used today in traditional Chinese medicine, primarily as an astringent. The tree has been grown extensively both in China and abroad as a host plant for the ailanthus silkmoth, a moth involved in silk production. Ailanthus has become a part of western culture as well, with the tree serving as the central metaphor and subject matter of the best-selling American novel A Tree Grows in Brooklyn by Betty Smith.
