I passed a house recently that had a pebbled front area and the only plants were these. They make a really bold statement planted on their own like this (but as they only flower for one week or so once a year I'd be inclined to put something other than just these and pebbles in your front area as most of the year it'll look kind of dull)
Here's a GLAMOROUS gold mannequin in the background, I think I'm going to call her Aaliyah after the Alium.
And here's Aaliyah. I think the song title is relevant for most gardeners trying to grow their crops :)
