In our Zone 7a garden: Patience is a virtue with this plant as it does take the two to three years to establish itself before flowering. But oh, is it ever so worth the wait! As for its purported dislike for being moved once planted…we have not experienced any horrific upset in the Baptisia australis plants we have moved around in our landscape design for one reason or another. Perhaps because we always amend the planting hole with compost or aged manure and add in a very generous helping of our homemade complete fertiliser before planting or transplanting any of our plants.
