Although Ozark Sundrops has absolutely no claim to be native to the Ottawa Valley, this startlingly large flowered species from central US is such a garden-worthy beauty, from time to time we include it in our offerings at Beaux Arbres. The flowers can be 8 cm across on a plant only about 20 cm tall

Ozark Sundrops’s lax stems sprawl just a bit, forming a low cushion, growing from a single tap-rooted crown, so it is never overwhelming. It wants well-drained, lean, neutral soil, and full sun. It does not compete against taller aggressive neighbours. A large sunny rock garden is ideal.

Ozark Sundrops is pollinated by large sphinx moths. Night-flying sphinx moths are not colourful but they are large and attractively patterned in white and cream and grey and brown. They are not attracted to lights, so spending a warm summer evening monitoring a stand of pale-flowered wildflowers, such as Ozark Sundrops, is the best way to monitor which sphinx moths are visiting your garden.
