Days to Germination:10-14 days
Baptisia australis. Start transplants indoors 2 weeks before the last frost date. Prior to planting, carefully nick the hard seed coat with a file and/or soak the seeds overnight in lukewarm water to assist germination. Pamper with 65°-75°F temperatures, good air circulation and even moisture. Avoid overwatering. Once seedlings are large enough to handle, transplant them into larger, deeper pots for full root system development. After all danger of frost has passed and seedlings are 4" tall, harden them off by gradually acclimating them to the outdoors over 7 to 10 days. Transplant out 18" apart in rich, well-draining soil and full to partial sunlight. Water regularly. Mulch to deter weeds and retain ground moisture. It will probably not bloom until the second spring. Established, it grows into thick clusters. Early summer flowering. Height: 36" to 48".
