Answer: Summer blooming lilies can be interplanted with annuals or perennials, but not planted over. The lilies sprout in early spring and send up a stalk which stays in place even after the flowers fade. The foliage on the stem should stay green until frost. The bulb will also increase over time and send up multiple stems, so you need to allow it room to develop just as you would any other plant. For planting in between the lilies you might consider some lower growing and trailing plants such as nepeta or perhaps some very early blooming plants such as violas. You might also consider annuals in a complementary color such as snapdragons or salvia "Victoria Blue".
