Palm Plants, Cycad Plants; Identification and Use

Palms are a very important group of plants, primarily throughout the tropics, but also extending into cooler areas. There are some palms which will even grow very well in temperate climates. There are palms growing successfully in cooler places throughout the world, including Tasmania, England, Canada and Cape Cod in the USA. Many palms however are not particularly hardy to the cold, and will be injured by temperatures approaching freezing point. In temperate climates, palms are also often grown as indoor plants.

  8. Special Assignment

Each lesson culminates in an assignment which is submitted to the school, marked by the school's tutors and returned to you with any relevant suggestions, comments, and if necessary, extra reading.

Aims

  • Distinguish between the characteristics of different types of palms and cycads.
  • Determine general cultural practices, including propagation, for growing palms and cycads.
  • Choose palms and cycads to suit different climatic situations.
  • Determine treatments for palms and cycads suffering various health problems.
  • Specify appropriate landscape applications for palms and cycads.
  • Explain different commercial applications for palms and cycads.

When deciding what palm or cycad to use in a particular situation, you should consider:

  • what the environmental conditions will be where you wish to grow the palm
  • what level of care it is likely to get
  • what soil (or potting media) conditions it is likely to contend with
  • size and shape of the species
  • growth habit
  • leaf type

Growth Habit
There are five types of growth habit, as follows:

  1. Solitary - these produce one single trunk with only one growth tip at the top. If that growth tip dies, the palm dies (which doesn’t happen as much with other types). This type looks clean, growth does not get out of hand, and it includes a large range of species; all of which go to make solitary palms common choices for use in landscaping or for other decorative purposes.
  2. Clumping - these produce multiple stems or trunks from the one root system (Suckers grow at or below ground level). Some produce lots of suckers, others only a few. Many can be propagated by division.
  3. Aerial Branching - normally this only occurs naturally in the genera Hyphaene, Dypsis, Korthalsia and Laccosperm. It can occasionally and abnormally be induced though in some solitary palms by tissue being damaged.
  4. Subterranean (under ground) Branching -this is known to occur in Nypa fruticans and Salacca zalacca. These can be propagated by separation.
  5. Climbing - around 15 palm genera contain species that climb, however few are of great significance with the notable exception of Calamus. This genus is in fact the largest palm genus (with well over 300 species), and the commercial source for rattan which is used to make “cane” furniture.
