Franklinia
Franklinia alatamahaFranklinia, or the Franklin tree is a small deciduous tree in the camellia family. It was first discovered by the Philadelphia based botanists John and William Bartram on the banks of the Alatamaha River in Georgia in 1765. William Bartram collected seed in 1773, and successfully cultivated the plant at the Bartram gardens in Philadelphia. Bartram named the new plant Franklinia alatamaha in honor of his father’s friend Benjamin Franklin. It is a unique tree as it is the only species in its genus, and it is now extinct in the wild. The original stand of trees was restricted to a small area and the species went extinct soon after its discovery, with the last confirmed sighting recorded in 1803. The probable causes for its demise were increased activity associated with settlers; for example fires and land clearance. All known living specimens in cultivation today are descended from the seed collected by William Bartram. Interestingly, while the tree was discovered in Georgia, it performs well in more northern climates. It has therefore been hypothesized that the tree was pushed south during the last ice age, then stranded when the ice retreated. The trees that the Bartrams discovered might have been the last remnants of a once much larger population. The Franklin tree is available commercially and is prized in cultivation for both its story and its fragrant camellia-like flowers and red fall foliage.

Hybrid White Lotus
Nelumbo ′Perry’s Giant Sunburst′Known for their beauty, the highly ornamental flowers of lotus are extremely fragrant and symbolic in many cultures. Emerging from the murky waters into the bright clear day is how Nelumbo nucifera, also referred to as the sacred lotus, first became a symbol of enlightenment. The fact that the sacred lotus is able to emerge without any trace of the muddy depths from which it was born is how it became associated with purity. Further elevating its sacred status, it’s reputed that Buddha rose up from the heart of a lotus bud more than 2,500 years ago.
