Natives of Mexico and the American Southwest, both Yucca and Agave plants belong to the family of Agavaceae.
In both cases their leaves grow in a spiral pattern out from the centre forming a ‘rosette’ structure.
Yuccas are less fleshy than Agaves and generally less spiny.
Yuccas survive in colder wetter climates than the Agaves.
Yuccas typically bloom every year with bell-shaped blossoms while many Agaves bloom only once and then die, and the flower has a very different shape.

Another difference between the two is that over time Yuccas will grow taller whereas the Agave only gets bigger.
This Yucca was growing in the hot dry climate of the Saguaro National Park in Arizona – that’s a Saguaro cactus peeking out of the bottom left.These Yucca trees with exposed trunks are in the Hortus Garden in Amsterdam. The best known of tree-like Yuccas are ‘Joshua Trees’ which have an entire American National Park named after them.This ancient Agave has grown huge in amongst the ruins of a church in Zacatecas, Mexico.
The Yucca ‘group’ features about 40 species, whereas the Agaves number around 300 species.
I’ve been exploring the interesting qualities of Yuccas and Agaves for awhile now. This Agave azul (blue Agave) in Zihuatanejo is one of the few without any thorns and perhaps, because of this, my little camera had trouble focusing. So it managed to turn a fleshy Agave into something that was delicate and ethereal. Watercolour painting in my sketchbook of a yucca in bloom that has grown tall enough to turn itself into a tree. This was inspired by a yucca ‘tree’ growing besides Las Margaritas in Vancouver.
- Agaves azules are of course the source of nectar to make tequila, and the best place to find that is to travel to the town of Tequila in Jalisco, Mexico.

With her photo challenge: Structure in Nature, Nancy started me writing a post on the rosette structure in plants. While putting together the post I realized that I had mislabelled many of my photos and ended up googling a lot of different plants to determine the differences. I didn’t manage to finish all of them but this is one of many!
