Gladiolus
The gladiolus is the line flower of late summer — reaching 150 cm on strong stems with 8–15 florets that open bottom-up over ten days. Snap off the top 2–3 unopened buds at purchase; they'll never open properly and steal energy from lower florets. A funeral and sympathy staple in North America, an everyday flower elsewhere.
