Heights can vary from plant to plant and from supplier to supplier at different times of the year. We will list this where we can, but because we have over 10,000 products available online, this information rapidly goes out of date, so we don’t want to supply incorrect information. If you need the actual height of the current product it is best to contact the nursery and ask one of our friendly staff. Larger pot sizes are consistently more mature plants with more established root systems, so this is why we size and sell our plants this way.
