Caucasian spinach (Hablitzia tamnoides) grows tall. Multiple harvests help control its growth vigor, and the installation of supports (trellises, stakes) allows you to exploit the vertical axes. Without support, it will fall back with just as much enthusiasm. From sun to shade, creeping or climbing, Caucasian spinach is a versatile perennial. Its mild flavor will please everyone; raw or cooked, it takes on an appetizing green.
