Historic Greenwich and the Royal Park (Part 1)Historic Greenwich and the Royal Park (Part 1)
June 19, 2010

Greenwich has more history than most people could research in their lifetime. From stone age tools found in Greenwich, the Romans in AD43, the Saxons settlement in the 10th century, to the Danes who in 1011 kidnapped Archbishop Alfege for a ransom, it is an amazing place. When the ransom was not paid, he was murdered and St. Alfege's Church stands in Greenwich to this day! Many of the things in Greenwich the tourists don't see, as they simply don't know about them.

This Southern Catalpa comes from southern Georgia, Alabama, Mississippi, northwest Florida, and a little of Louisiana. Its opposite, heart-shaped leaves are 4 to 10 inches long by 3 to 8 inches wide. Its flowers are in denser clusters and with more yellow and purple in the mostly white flowers, and it blooms about 2 weeks later than the Northern Catalpa. Its pods are 6 to 15 inches long and are thinner-walled than the Northern's. The Southern species is a smaller tree growing usually 30 to 40 feet, though 60 feet is possible. I've only seen one specimen at an arboretum in southeast PA, so she is not nearly as common as her big sister, the Northern Catapa.
