Beautiful Baptisia

by Judy DeFiglio

If you are looking for a spectacular plant for your spring garden consider the Baptisia australis (Blue False Indigo). Big, bold, blue and beautiful, this plant has it all. The intense violet-blue pealike flowers on four foot tall stems really command attention. The leaves are an interesting blue-green color with an oblong shape. The flowers are long lasting and followed by two inch long black seed pods that add an additional season of interest to your landscape. The plant emerges in spring with flower stalks that look almost like asparagus, then grows several feet to bloom in mid May.

Baptisia prefer full sun but can grow in part shade. They have a deep taproot and do not like to be divided or moved, so plant them where you want them to grow. I recommend you plant them in the back of the border or center of an island bed. Though this is a perennial, it is shrub-like in appearance and gets three to four feet wide, so give it room to grow. Even after the flowers fade this is a plant that will look good in your garden. It may be large but it is not sprawling and retains a nice vase-like shape.

This native plant grows well in our sandy soil, but enjoys a bit of compost mixed in, especially if you are growing it at the beach. It even has a good degree of salt tolerance. Since it is in the legume family it has nitrogen-fixing ability so no fertizer is needed, great news for our environment.

While the blue is my favorite, there are also white and yellow flowered varieties of Baptisia. All of them put on an impressive display.

I am very excited about all the enthusiastic gardeners I am meeting as I continue to spread the word on using native plants to beautify their landscape and help the environment. I will be posting updates on workshops and lectures and hope to meet lots more of you in the future.
