The first 2024 plant knowledge base post.
Blossfeldia liliputiana
(bloss-FEL-dee-uh) Named for Robert Blossfeld, a 20th century German hybridizer
liliputiana - a reference to the fictional island of Liliput (Gulliver's Travels) whose inhabitants were said to be rather small
Common Name: Miniature Button Cactus
Origin: Southern Bolivia to north western Argentina
I love our cactus shows and sales because you never know what you will find; and I have wanted one of these for quite sometime, and its here. This is the Blossfeldia liliputiana - the worlds smallest cactus. This whole clump is ~ 1.5 inches across.
These guys come from Bolivia and Argentina where the grow mainly on rocky outcrops and cracks in rocks. This cactus is slow growing
needing 2 to 5 years to become fully grown. Often in collections, like this one, they are grafted to make it easier to take care of. This also speeds
the growing time but they do become more ball like instead of a flatter disk shape like in the wild.
This cactus is the only cactus that is poikilohydric. That means they are capable of complete drying out, and then re-hydrating their cells when watered.
Apparently it has been found that they can lose 80% of their moisture in a year, and go for another year of drought, then come back after the drought is done.
Also,Except for certain parasites and aquatics, this species possesses the lowest density of stomata of any terrestrial flowering plant. Stomata are the pores in which plants regulate water and gas exchange so having so few may have something to do with why this species loses and gains water to such a degree that would kill most other vascular plant species.
As a cactus this is a summer grower. It, hopefully, will flower with little white and yellow flowers.
Liliputianas do not have spines but little trichromes that a soft.
Hope you enjoyed that litte KB update. I will have more throughout the growing season.
