This unusual but easy annual has so many names, I hardly know which one to pick. I started it from a very old pack of Thompson & Morgan seed labeled “Viscaria oculata cardinalis Ruby Flax,” but it has undergone several taxonomic changes since that packet was printed. It seems to be currently known as Eudianthe coeli-rosa ‘Ruby Flax’, so that’s what I am going with here. Whatever you call it, it’s a beauty, producing a bounty of brilliant red to pink blooms atop clumps of slender stems carrying narrow, bright green leaves. The height is usually around 1 foot but can be taller in rich, evenly moist soil. It starts flowering in late spring to early summer and continues through at least part of the summer, tending to fizzle out if high temperatures really set in. (Here in my southeastern PA garden, it flowered well into August, even during prolonged hot weather.) ‘Ruby Flax’ rose of heaven is eye-popping in a bed or border and can perform well in a container too. I suggest growing it in a pot by itself, so you can display it when it’s at its best and swap it out for something else once it is past its peak. If you allow the seedpods to mature on the plants, you’ll probably find self-sown seedlings the next season. Full sun for best flowering. Annual.
