Botanical Name:Hibiscus moscheutos
Common Name:Hardy Hibiscus
Native Region:North America
Hardy hibiscus, Hibiscus moscheutos, is a deciduous shrub that grows from 4 to 7 feet in height. Related to hollyhocks and prairie winecups, the hardy hibiscus is native to the U.S. In the wild it is found along creeksides in the southeastern states. Late summer and early fall are peak bloom times for the plant. The flowers of the hardy hibiscus can be up to 8 inches across – salad plate size. Typically in shades of red, pink or white or in a combination of these colors, the flowers bring a tropical feel to any landscape. Unfortunately, the dramatic blossoms only last a day.
Garden Location:Perennial Walk, Lilac Garden
Botanical Name:Tabebuia heterophylla
Native Region:Puerto Rico and Cuba
Tabebuia heterophylla is a medium size, semi deciduous tree. In areas where it experiences a distinct dry season, there is an explosion of pink flowers in mid winter. In landscapes where it receives year round moisture (including in our conservatory) the bloom season is extended over a longer period with fewer flowers appearing at any one time. Tabebuia is gaining popularity as a source of wood for furniture and flooring.
