The Bismarck Palm: A Noble Spectacle
By Kayla Kling, Education Intern, Reiman Gardens, Iowa State University
Known for its large gorgeous leaves that can reach up to nine feet across, the Bismarck palm creates an amazing focal point within a southern landscape or within a large container or conservatory in the north. The Bismarck Palm received its name from the former chancellor of the German Empire, Otto Von Bismarck. Its scientific name is Bismarckia nobilis, “nobilis” being Latin for noble. It is typically grown in Florida, California, and Texas, where the warm and sunny climates help reach its full potential.
This spectacular tropical fan palm has a massive and corpulent trunk, which is necessary to hold up the bulky leaves. It is a single trunk with radiating large leaves on petioles (or “stems”). The leaves appear like silver-blue fireworks exploding from the stem and prove a remarkable site. The flower stalks are four feet long and produce 1.5 inch long fruit. Some have said that the nuts from this palm can create unique vases. The Bismarck palm is native to the drier parts of the African island of Madagascar and desires subtropical landscapes. Yet, after establishing itself for two to three years the palm can survive in climates of 26°F. It requires frequent watering (two to three times per week), but once established the Palm grows rapidly. In five years it can grow 15-18 feet high by 10-20 feet wide, with an average growth of one to three feet per year. Yet, if this palm is grown indoors it may not reach such heights, due to temperature and sun exposure.
The immense tropical fan commands attention wherever it is grown. But because of its large size and cultural needs, the Bismarck palm is not recommended as a permanent plant in Iowa and is best as a young plant in containers instead. Occasional pruning is beneficial for the development of strong structure. Be advised that the Bismarck palm does not like to be frequently moved from pot to pot. In southern states the palm is often used as a focal point in the landscape. The Bismarck palm is adaptable to many different types of soil and prefers full sun, but is tolerant of some shade. Once the palm has established it is also drought tolerant and not as subject to disease and nutritional deficiencies as many other landscape palm species. The Bismarck palm’s tropical flare is hardy in USDA zones 10 and 11 or may be successful in a container or featured in a tropical conservatory.
The Bismarck palm is clearly visible as a strong focal point when walking down the main hallway of Reiman Gardens’ Conservatory Complex. Stop by soon to see this fascinating attraction.
