Gladiolus 'Carolina Primrose' was discovered at an old abandoned NC residence, a tribute to its amazing durability. For us, this extremely hardy form (or hybrid) of Gladiolus dalenii var. primulinus makes a fast-multiplying clump that produces 3' tall flower spikes from mid-June through mid-July in NC...attractive to hummingbirds. The floral spikes are laden with soft butter yellow flowers darkening toward the throat, where you will also find small reddish-brown stripes...that's stripe throat, not strep.
