Grown from seeds produced by a variegated version of this cultivar, these plants aren't producing variegation themselves but appear to be fairly sturdy growers with deep green foliage (and thorns, like most citrus), and once they start maturing in a couple of years should be capable of producing tangy, mildly sweet yellow lemons with bright pink interiors; you can make pink lemonade without adding food coloring!
Available plants are between 5-7 inches tall.
