Of course the so-called Obedient Plant never will be as obedient as a dog — it’s not going to roll over or fetch — but there’s a reason for its name. Bent, twisted, or arranged around the stalk, individual flowers tend to stay put; arranged in parallel rows, the effect can be charming.
These Spring Obedient Plants (Physostegia intermedia) found near the San Bernard Wildlife Refuge will bloom until late June or July; the so-called Fall Obedient Plant (Physostegia virginiana) appears here from August to October. While the doubled stem shown above is unusual, the curves of the developing flowers always are attractive.
The flowers open from bottom to top along the stem, and visiting bees seem to move in the same direction. Tubular, two-lipped blooms offer a handy ‘landing pad’ for the bees; entering one flower after another to gather nectar, the bees then back out, carrying pollen with them as they go.
The plants are less obedient in the garden. A member of the mint family, Physotegia spreads easily; like mint, it can fill flower beds if not contained. Still, that same tendency to naturalize allows it to provide great sweeps of color across the landscape. Whether straight and tall as the snapdragons it resembles, or delicate and curved in development, it’s a welcome sign of spring’s continued unfolding.
