How about some fun wordplay in honor of this spectacular perennial?

Have you seen the 'Holy Grail' of cup plants?

On very tall stems their daisy-like yellow flowers gently wave, while

Leaves of chartreuse or even 

Yellow-gold clasp the stem,

Giving rainwater and dew a little cup to 

Rest in

And be visited by thirsty creatures. 

In July or August they bloom, 

Lending a picturesque quality to their patch of soil and sky.

Note: 'The Holy Grail' Cup Plant boast large rosettes of foliage that emerges chartreuse and then fades to green as the plant climbs to 6 feet tall.  

Conditions: Full sun; average, moist and well-drained soils
Size: 4'-8' tall, 2'-3' wide
Zone: 4 - 9
Wildlife Value: Birds eat the seeds, and birds and insects are attracted to the water held by the cupped leaves; flowers support bees and butterflies
