Hmm. Well I have grown it on several occasions and will do again once
I can clear away some shade-causing plants which have dramatically
reduced sunny spots in the garden :| It is not a true bulbous plant
nor are the roots tuberous. When it enters drought induced dormancy,
the terminal growths can become somewhat thickened, but to classify
them as bulbs is stretching terminology somewhat. As a garden (or
greenhouse) plant, this Bulbine usually remains evergreen and is a

adventitiously rooting rhizomes at or just below the soil surface.
