Echinocactus Giant Barrel Cactus Seeds

Echinocactus Giant Barrel Cactus is native to central Mexico and is the largest of the barrel cacti, with some of the very mature specimens (more than a hundred years old) reaching more than 150cm across. Fortunately, this is a relative slow growing species, which for the most part, will result in substantially smaller plants in the garden, typically reaching the size of a soccer ball in around 5 or so years, and requiring 20+ years to reach the size of a beachball. If you are after a larger plant, best not to wait and get the seeds in now! Or perhaps visit a local nursery. Echinocactus Giant Barrel Cactus does well in pots, rockeries and a wide range of gardens, and like all cacti is very drought tolerant, making it a favourite for pots or garden beds where established plants are expected to survive with very little water or attention. The bold and beautiful shape and texture make this variety a great addition to any garden, and can be used quite effectively in making a statement as a specimen plant. The Giant Barrel Cactus is a variety of Echinocactus platyacanthus.
