Unusual Caudiciform Plants – Fat Plants

Caudiciform plants is a large group of plants that form caudex – a fat stem or root. The caudex in most Caudiciform plants is prominent and gives these plants a uniquely unusual shape and character.

Caudiciform plants make excellent specimen plants. Take the example of Adenium obesum, Beaucarnea gracilis, Cycas revoluta, most Cyphostemmas, and Dioscorea elephantipes. Like other Caudiciform plants, these attractive plants form caudex to store water and food so that they can survive long spells of drought therefore these are generally low-maintenance plants.

How to take care of Caudiciform Plants / Fat Plants

Caudiciform plants do not require much maintenance. Because they are able to store water for dry periods, you do not need to water them regularly. During the months of active growth, water sufficiently only when the soil is completely dry. Avoid watering when the plant is hibernating.

Grow your plants is a well-drained soil and feed them when they show active sign of growth. With a little experience with caudex forming plants, you will understand that most of these plants quick adopt to the surrounding climate. You can grow them outdoors as specimen plants, indoor on a window sill, or in a greenhouse (if you live in a colder region). Generally, they prefer dry conditions and good exposure to the sunlight.

Types of Caudiciform Plants / Fat Plants

Caudiciform plants come in all sizes. Some grow into tall trees, some have shrubby growth, some of them are vines and some of them are small succulents. The size, location, and shape of caudex in most plants vary greatly. Therefore, these caudex forming plants are further grouped in four categories.

  • Phanerophytes: These Caudiciform plants form succulent base which appears prominently above the soil level. Most Adenias, Beaucarneas, and some Pachypodiums are good examples of Phanerophytes.
  • Chamaephytes are Caudiciform plants that form caudex at their base. The caudex in these plants may or may not be prominently visible. Dioscoreas belong to this group of caudex forming plants.
  • The caudex in Hemicryptophytes is usually formed below the ground but the growth is usually above the soil level.
  • Geophytes are caudex forming plants that form both their caudex and the growing point underground. Ibervillea is a good representative of this group.
