The American Association of Botanical Gardens and Arboreta Web site has a listing of the major botanical gardens in the whole country, sorted by state or region, including Canada and other places outside the US. You can choose categories: arboreta or botanical gardens, historical sites, or nature centers, and also check on facilities such as food, a library, a retail shop. The list also gives many different horticultural features, such as ferns, wetlands, a conservatory for rainy or cold days, and various programs available. You can click on most sites for the Web site of that garden. There is also information for those who work or would like to work in a public garden, and a list of over 700 internships available.

Trumpet trees (Tabebuias), blooming now or soon to begin, are one of the most spectacular of all our flowering trees. There are over 100 species, at least 15 of which are grown commercially in Florida and vary in height from 15 to 40 feet. Most are deciduous, a few are evergreen. Some have yellow flowers, some have pink or white. The large clusters of trumpet-shaped flowers shout "Spring!" Certain species bloom a bit later than others. Stuart, Florida, has these planted all along the streets, and they are a sight to see when in bloom, which was as late as April 18 the last time I saw them. Unfortunately, the blooms come and go quickly. They need sun, have high drought tolerance and medium salt tolerance. They do not survive heavy frosts, but mine has not been even nipped yet in the Tampa area and has quickly grown from a seedling to a 15-foot tree.
