I posted about this last year, at the end of September, when it first flowered after planting that Spring. Mathilde, who gave me the bulbs, calls it Fleur de Lys and Titania in Australia supplied the botanical name - Sprekelia Formosissima. It's a glowing clear red and this photo doesn't do it justice.
I read that they're native plants of Mexico, love the full sun in well-drained soil and will flower twice a year. When the bulbs have multiplied I'm going to add more around the inner garden.
