Tiny bulbs

There are several small, blue-flowered Griffinias and even Griffiniopsis
blumenavia (Hippeatrum/Amaryllis blumenavium). Both these are tender and
need at least 75% shade.

Also, I have Cyrtanthus hybrids (ex Greg Petit) that flower all winter long
and is under 12 inches tall which would do well in a trough.
