Yucca gigantea

Yucca gigantea or giant Yucca is a succulent from the Agavaceae family and the largest Yucca.

It looks like a tree with a thickened trunk.

Giant Yucca can be grown both in the garden and in pot as a houseplant. It tolerates only mild frost for a brief period of time.

It is a very easy drought tolerant plant.


Yucca gigantea can grow to 3-10 m tall, with a spread of up to 4.5 m.

The trunk is thick and swollen at the base, narrower higher up, with few ramifications. With age, the trunk looks like an elephant’s foot.

The leaves are elongated, flat, dark green, 50-100 cm long and 5-7 cm wide, pointed at the top, with finely toothed margins.

The white flowers appear in spring and summer in an upright spike.

The fruits are brown, fleshy, oval and be up to 2.5 cm.

Seed, suckers, stem cuttings

Sowing instructions:

  • the seeds germinate better after 2 months of stratification: place them in a refrigerator (do not forget to note the date)
  • soak the seeds 24h in lukewarm water
  • sow in a moist and sandy substrate
  • if you can maintain the temperature between 28-32 °C, the seeds can germinate in 4 days. At lower temperatures (20-25 °C), germination will take longer: 1 month to 1 year.

Stem Cutting:

  • if your houseplant gets too big, simply cut the stem at the desired heigth
  • remove all the leaves and plant the stem cutting in a pot with soil mixed with sand
  • place in a shady spot
  • root formation occurs in 2-3 weeks
  • the lower part of the plant will form new leaves
