Spanish Flag

Ipomoea lobata
Native to Mexico, this showy vine was introduced in 1841. This member of the morning glory family has arching sprays of tubular flowers that change from crimson to butter-yellow, giving a delightful multi-colored effect. Grow in a large pot with a trellis for the twining stems to catch hold, and fertilize only with low nitrogen flower fertilizer as the first buds start to form. Best in a warm, sheltered spot, where it will twine upwards and start to flower late summer to frost.
