Nursery contributed plant descriptions

Cute little fall blooming bulb with dense spikes of star-shaped flowers. Somewhat variable; we ended up with some blooming pink with yellow anthers and some lavender-pink with purple anthers. Easy in most decently drained soils.

Prospero autumnale Used to be Scilla autumnale, but now is prospering in the garden under this fancy new name. Whatever you call it, great loose spikes of handsome blue flowers in late summer (July/August for us) followed by unobtrusive foliage. A perfect pick-me up for a tired late summer garden. Zone 5, at least? Joseph
