Yes, it is easy to grow, and it prospers in dry soil. Very attractive yellow flowers attract bees and butterflies.

I'm growing Carolina Lupine in part-sun on a hillside with sea oats on the coast of Maine, looks lovely. I'll be trying to grow more from seed. Might combine well with switchgrass also.

Carolina Bushpea is a Southest U.S. native, found growing wild in forest clearings. It will grow well in most areas, although it is a slow starter from seed.

For best results, give the plant plenty of room to grow. It can dominate the border in early spring with its size and striking flowers.

Can tolerate some dryness, although it will do best with moist soil. Has a long taproot, and does not transplant well.
