22 flowering houseplants
The catalogue marks each species as flowering or not; these are the marked ones that cannot take frost, so they are grown indoors here. A winter rest is not a fault to fix: for many of them the short days are part of how the next flowers form.
In the table, watering runs from 2 to 35 days at medium light; 13 of the 22 want humid air.
