Description

Blue Wild Indigo Seeds 6875 (Baptisia australis). A bold and very ornamental eastern North American native that produces beautiful clusters of lupine-like blue flowers from May through June. A bumblebee favourite! This drought tolerant plant was once used to make blue dye. After the flowers die off, visually interesting swollen charcoal black seed pods about 5 cm (2″) long form on stems that are in demand for dried flower arrangements. Mature seeds in the pods rattle when shaken. Grows in full sun or partial shade in a rich, well-drained soil. Height 60-90 cm (2-3′) or more with an equal width. Absolutely underused in gardens and landscapes. Once established this plant is very drought tolerant. Requires at least three years in the garden to truly establish and show its full potential. Once it does, a very interesting looking, long lived perennial will reward you for your patience. If your intention is to commercially produce transplants, experiment for a few years to determine the best technique for your growing conditions. Perennial hardy to Zone 3.

How to Grow

48 seed/gram. When direct sowing seed outdoors, due to possible dormancy caused by a hard seed coat, seed is best sown in late fall. This allows the seed to naturally stratify over the winter. Indoors, sow seed March 1st in a soil-less mix using plantable fibre pots but first gently nick or file the hard seed coat to improve germination. As an option to this, soaking the seed in warm water for a day has also been shown to improve germination. Maintain the growing medium at a temperature of 20 C (70 F) for the 10-15 day germination period. After germination, grow on under lights at a slightly cooler temperature then harden off and transplant outside to a sunny to partially shaded site with rich well drained soil. Due to the formation off an extensive taproot, this plant does not transplant well so care should be taken during the initial site selection.
