No, it’s not a sea creature out of water. It’s a super freak, super freak, super freaky (Rick James approved) mutated succulent!
Fasciation, cristate, cresting, or bundling: all are words for an interesting genetic mutation that causes a plant to grow gnarled and twisted, thick in some parts and thin in others. Sometimes the plants appear super-pumped, almost as if it were doubling and even tripling back onto itself. These mutations, often occurring at the tips in new growth and sometimes even in the flowers, are triggered by a range of traumas ranging from environmental issues such as chemical exposure and frost, to insect attack, over-crowding, and disease.
And then plant breeders take these random mutations and use them to their advantage to produce far-out, freaky, alien varieties, such as this Echeveria runyonii ‘Topsy Turvy Cristata’.
