It ought to be more widely available because any Zantedeschia aethiopica is easily propagated by dividing the corms into pieces, every bit will form a new plant as anyone trying to remove mature clumps will discover. I don’t know why Plant Delights stopped offering it, but it may be due to the hotter conditions there in North Carolina the variegation wasn’t as prominent, and purchasers might have complained that it wasn’t “prime”. In my cool summer conditions it shows excellent variegation throughout the year and is clumping up nicely.
