garlic

Is there a type of garlic that actually flowers? I've been reading 'Dracula' (in between reading the Master and Commander books) and Van Helsing brings garlic flowers to put around Lucy's window. Was Stoker just not thinking about that? The garlic we have grows scapes, which are like flower buds, but they never open. They develop tiny kernels, very tiny garlic cloves, which, if you plant then, will take two years to grow into actual garlic. It's in effect like corn (maize); which is also a grass, so I guess that makes sense.
