Odd statements in that Walmart description, such as "..that is the only known triploid daylily." (No it's not the only one) and: "Often referred to as a diploid, Kwanso actually produces triple the usual number of petals and as such, is a triploid daylily with its stamen modified into additional petals.". I think someone doesn't know what diploid and triploid mean. They got "aggressive" right though, it's pretty but it will take over the garden if you let it.
