Discovering new or unusual plants is one of the great joys of gardening, and master gardener Paul James is always on the lookout for anything new. Here are some of his plant finds:

  • Roger's flower (Rodgersia). These plants are grown for their attractive foliage (figure A) and stately flower spikes (figure B). They will grow to five feet and are hardy in Zones 5 and 6. They prefer rich, humusy soil and a shady site. They also need a steady supply of moisture. They make a great bog plant, because they actually enjoy wet feet.

  • The native Jack-in-the-pulpit (Arisaema triphyllum) has several Asian cousins that add sparkle to any landscape: The showy cobra lily (Arisaema speciosa) (figure C) and the tortuous cobra lily (Arisaema tortuosa) (figure D).

    All arisaemas--which some people refer to as hardy tropicals--are hardy to Zone 5 with winter protection. They're true woodland plants (figure E), and they must be grown in a well-drained, moist soil that's high in organic matter. They also need shade most of the day, although a little morning sun or dappled light is okay. When placed in the right spot in the shade garden, they are quite showy.
