In a July, 1950 column for the Observer, Vita Sackville-West writes that the two most popular varieties of Alstromeria do not mix well together thanks to a striking color clash. It leads her to note that:
" . . . whoever it was who said Nature made no mistakes in colour-harmony was either colour-blind or a sentimentalist. Nature sometimes makes the most hideous mistakes; and it is up to us gardeners to control and correct them."
All gardening takes hubris, of course. But perhaps not always quite this much.
