Description

Skyblue Lupine is a beautiful blooming perennial but a very finicky plant to grow. It requires two things to grow: full sun and well-drained sandy soil. Native habitats include scrub, coastal strands, sandhills and pine flat woods. Its seeds can lie dormant for years, waiting for just the right conditions to germinate. Here in NC it only grows in the southern coastal and coastal plains areas.

It has lovely pea-like blue flowers in early spring with hairy velvety leaves. However, It is very difficult to transplant due to a deep taproot and it doesn't like being moved at all. This makes it very difficult for commercial growers as the seeds do not like being started in pots. So it is best to just enjoy it in its native habitat and help preserve that habitat.
