cover a good deal of space and send up a crowd of 
yellow, feathery flower heads. S. Virgaurea nana,

any odd corner, the Solidago will be looked upon as 
a plant of unbounded possibilities.

weeds in the spongy, moisture-laden soil, yet so 
elegant, so airy and dainty that they never appear

varieties is wide. We may have truly herbaceous 
sorts or shrubby kinds, and of the latter there are
