That's a beautiful combination Terri! That's exactly what I've done here (in May I'll have lived here 3 years), bulbs and annuals to provide color till the perennials fill in. Only problem is now I've grown so fond of many of these annuals, and still want to devote space to them (now that the perennials are taking off).
This pic was taken standing by the butterfly garden, I recall loving being able to see the Lilies in the background, middle, and foreground.
