We purchased this lovely form of Agave americana in 2005 from a grower in Thailand. Unfortunately, it came without a valid cultivar name, so we’ve named it Agave americana ‘Marshmallow Cream’. Agave ‘Marshmallow Cream’ has a much wider and shorter leaf than the typical Agave americana ‘Marginata’, which is more common in the trade. Agave americana ‘Marshmallow Cream’ also makes a much more elegant plant in the ground as well as in a container. Since it isn’t winter hardy for us, we can only guess about a mature size, but we would expect 5′ tall x 8′ wide. Quantities are very limited.
