Colchicine is also used as a mutagen in horticulture, often of cannabis but also orchids, tulips and other flowering plants.

Applied in 0.25% solution as a soak for seeds or directly to the primary meristem (growing tip), it inhibits chromosome segregation to daughter cells and cell wall formation, resulting in larger-than-average daughter cells with multiple chromosome sets: (polyploidy). This results in taller, bushier plants, more leaf mass, and bigger flowers.

Perhaps future genetic microbotanists will find a way to lock that condition and give us strawberries like grapefruit, but for now polyploidy, even when induced in seeds, does not "take" permanently, so after a very few generations the plants revert to a normal diploid state.

As noted above, Colchicine is very toxic so no part of a plant to which it has been applied should ever be consumed; either soak the seeds or use second-generation offspring of the treated plants.
