The Book of Little Hostas by Kathy and Michael Shadrack
(2010) says: "This early emerger will require care. Morning sun is
best and plenty of water desirable. So small, this little plant is only really
suitable for the ceramic container or bowl."
The New Encyclopedia of Hostas by
Grenfell (2009) states in its Miniature Hostas chapter: "Watch
carefully for possible slug and snail damage. Grow in raised
borders dedicated to the tiniest hostas...not allowing it to be
swamped by other plants. Do not divide until the clump is about
five years old and has at least six crowns...A typical form of
H. venusta but scaled down in
size; it is about the same size, or slightly larger, than H. 'Uzo
No Mai', which has no petioles and is virtually impossible
to keep alive for more than a year or two."
