Two years ago I purchased a bag of Oxblood Lily bulbs also call School House Lily since they were often plants in school years. The bulbs I purchased came from the Southern Bulb Company is Texas. The story is that the Oxblood Lily is native to Argentina and was brought to Texas by German settlers many years ago.
The pink Oxblood Lily bulbs are hard to find, red flowering bulbs are more available than the pink. In September they will bloom and then the green foliage appears and stays green all winter. The flower stalks are around 12 to 15 inches tall. They will come back every year. Last year I had flowers but they are taller and more beautiful this year than last year.
