If you appreciate vivid violet colour, colour, colour, then you will want blue false indigo (Baptisia australis) in your garden. Simple, sweet pea-like blooms stack into spikes of blue-purple. The soft, lush leaves grow in triples (trifoliate), creating an all season bushy backdrop, also with a tint of blue. This member of the pea family likes full sun with soil on the sandy side, and is drought tolerant once established. The flowers dry to brown-black seed pods that make a creative addition to dried arrangements, or second as noise maker rattles! This taller perennial is at home towards the back of the bed, and makes a striking colour combo with scarlet oriental poppies (you can see bits of this colour combo by clicking here).
Technical stuff – Blue false indigo/Baptisia australis, hardy perennial to zone 3, height and spread of about 3’, prefers full sun and well-drained soil, blooms May into June.
