A beautiful perennial. Lovely blue-green foliage looks good till hard frost. The flowers resemble lupines but are looser and more relaxed.

My one wish is that the flowering season were longer.

Baptisias can take up to five years to reach their full size.

I have 5 different varieties in the yard. It does become a huge bush/shrub. I have successfully moved & or divided oldest the plant in the past. But know - if you try this more than likely half the plant will die. I took it apart in the spring after blooming. Mine naturally broke into several pieces. I gave them to others all have survived & did recover over time. I am going to try another this fall to see what happens. Let you know next spring.
Now about the seeds. I have NO trouble getting seedlings from this same mentioned plant my drive-way has dozens every year. I do dead head in the spring, but I can miss a pod(s). I think for best results the seed should be on top of the soil. Do not cover them. Or broadcast them in the fall & let Mother Nature take its cour... read more

A must have in the garden. Indestructable and growing as a backdrop to our birdbath for over 10 years.

Beautiful native plant of eastern North America. It is one of the perennials in a standard garden that is best to leave undisturbed, to not dig up and divide, as it is difficult due to big taproots and it does not have the middle die out. It is also wonderful for native meadow and prairie restorations. It stays as a 3 to 4 ft high herbaceous bush that might need some staking when it is at its tallest. As a legume it fixes nitrogen to the soil. The pods can be used for dried arrangements. Plants from seed take 2 to 3 years to bloom. My specimen in my backyard prairie garden has not ever made seedlings here in se PA.

I planted this about six years ago. It now grows from the ground into a "semi-shrub" about 4' tall and wide each year. I'm impressed with its frost hardiness - it can take up to -10C and still be green and leafy well into November. I haven't had a huge number of blooms, maybe 10-15 sprigs on the whole plant each spring, but they are pretty (as are the seed pods) and the foliage itself is quite attractive.

I am growing this plant in zone 6a, it has not flowered yet but I only planted it last year. Reassuring to see from others' comments that it will likely bloom next year.
If you see caterpillars on your plant, please tolerate them and let them live! This plant is known to be host to some beautiful butterflies, among them the Eastern Tailed Blue, Orange Sulphur and Clouded Sulphur butterflies. Not everyone realizes that caterpillars turn into butterflies, or perhaps they don't think of it when they see damage to their plants. Even some who planted "butterfly gardens"!
As formerly wild spaces and meadows are developed, more habitat is lost. We can try to create more in our gardens so these beautiful species can hopefully survive.

My rating is neutral only because I screwed up and planted this too close to a black walnut tree. I did not know at the time that I had black walnut trees or that they emit a substance toxic to certain plants. So in my experience, baptisia is NOT juglone tolerant. This poor thing struggled valiently for a year and then died -- but it whetted my appetite for baptisia in general and now I have some lovely ones in other areas of my yard.


On Jun 22, 2013, plant_it from Valparaiso, IN wrote:

Native to the middle U.S., Blue Wild Indigo is at home in both formal and naturalized gardens, providing early season nectar to a variety of butterflies and pollinators.

Although it is a perennial plant that dies back to soil level in the fall, blue wild indigo grows to look like a small multi-stemmed shrub once established. Consider placing it in your garden plan as you would a small shrub, giving it room to spread into its rounded form. The plant produces a long tap root (which gives it some drought tolerance once established) making it difficult to transplant after a year or two.

I have had my Baptisia plant for 7 years now. All I can say is BEAUTIFUL!!!! I have outside the front of my house, and it is monstrous! All day Full Sun, it thrives there! I live in Iowa, harsh cold winters..... extreme heat, it gets bigger and bigger! Mine produces blue purplish flowers.... Gorgeous! I decided to pour miracle grow on it this year, HOLY MOLY, I have surpassed the 5ft mark!!!!! Im guessing 6 ft tall, 6 ft wide. I did once, open the pods in the fall, froze them, and tried to plant in spring. No luck. Also tried to split the root ball, NOT HAPPENING, too big! So now just living with the one monstererous beauty I have. :)

I picked up my plant for $3.00 at Canadian Tire in Edmonton, Ab, Canada (Zone 3-?) 3 yrs ago. I liked the foliage of the little plant and while I didn't remember the name of it, instructions said to lift it in the fall. I forgot and was very surprised it grew the following spring. We have severe temperatures here in winter 25 to 30 below a few times during winter. I took no special care with covering it during winter and it came up the second year. The third year it grew again beautifully, it is now 18 inches high - and in May it was covered with beautiful blue blossoms, about 15 in all. Needless to say, I'll be more careful readying it for winter this fall. This has been our "Mystery Plant" and we're happy it now has a name.

I got a start of this plant last April at a historic home garden attraction my garden club went to. There had been a sale the previous weekend and we were allowed to browse the left-overs. They made a fortune off of us, lol. I was thrilled to see the baptisia because I had been looking for some that wasn't expensive like the mail orders. I planted it in a front bed with full sun. It did well last summer and is coming back up. I don't know if if will bloom this year, but I am glad it survived the icy winter.

It did take this plant 3 years to bloom for me in my garden.
I would like to try the real indigo so that I might learn how to make the dye that will not fade. Does anyone have any idea where it is available for purchase at and where it will grow?

I have had these plants for years and most of them are in part shade.
They bloom every year without fail. However, I have one that only has one shoot coming up. This plant was one of my best bloomers but I don't understand why I only have one shoot. I have coneflowers coming up close to it. Could they have wrapped their roots around the shoots before they had a chance to pop through? I've carefully dug out the coneflowers and hopefully the Baptisia will still have a chance.

Baptisa grows well in our part of NZ, but although the plants have been in for almost 3 years there is no sign of flowers, which is disappointing. It certainly tollerates drought and clay soil, which is good.

I first saw this plant in blue/purple at the Botanical Gardens in Chapel Hill, NC. It was about 4 ft tall and in full bloom. It was so close to being blue that I just had to have one. That was about 4-5 years ago and the seedling I started out with was VERY small. Now, it reaches a smidge over 4 ft, and is covered with blooms each year. My plant is on the end of my house which faces west, so it gets full sun from mid-day until about an hour before sundown. It is very hot in that location, but it seems to handle it just fine. I have had seedlings pop up around it, but have not attempted a transplant yet. In the same bed I also have a white version and an electric yellow version which both have the same cultural requirements, but don't get as large as the blue/purple. The yellow see... read more

I grew this from seed. It was slow to establish in the garden (of course I moved it the second year, which many have something to do with it). It is now about 24" tall and has lovely shape and foliage. It is not yet bloomed, however, but I am hoping it will next spring. This is the first year since I started this from seed three years ago that it has become a reasonable size, so perhaps it is simply slow to mature from seed.

I love this plant. It's in full sun here in hot and humid Texas and it bloomed beautifully this year which was it's second year. The first year it was puny and dissapointing.Then the leaves turned black and shrivelled and I found loads of tiny caterpillars all over it so I cut it back about 3 weeks ago. Then it started sprouting again and is about a foot tall but again the caterpillars are back and are stripping the plant and turning the leaves black. Does anyone have any experience of these wretched things. They are nearly an inch long, greeney yellow with black markings. I'd rather not use inecticides and I guess the best way will be to try and pick them off. Any advice will be appreciated.

I've had Baptisia growing in my Zone 7a yard (Petersburg, VA) for ten years or so, and it has been moved around and survived. It does take it time to adjust, but it has not died. I have also started new plants from seed. I have not scarified them but leave them outside in pots over the winter. I have been pinching the seedlings back, hoping to promote thicker growth. I enjoy its lupine-like leaves and blossoms, as lupines do not thrive in our summer humidity.


On Jan 20, 2010, JonthanJ from Logansport, IN wrote:

We planted several of these in late 2003. They have developed handsomely. They come up so quickly that people should think of it as a late spring flower with handsome growing foliage through the summer and into the fall. The mature clumps are so big that they hold up against our big clumps of ornamental grasses. Seedlings have come up under several of ours. We even appear to have a shoot coming up from a root that had grown out through the bottom of a pot.

The available plants are surprisingly variable seedlings. Different plants will give flowers at different places on the scale from sky blue to nearly purple. They will also bloom at slightly different times and display slightly different growth habits. One of the big garden differences is the degree to which individ... read more

This plant did not bloom for me until the 2nd year. At that time, I did get several flowers in the spring, however it grew much taller (5 ft.) than I had expected. I am in Zone 4. We have had an exceptionally cool summer & I believe that it may have had a different growing pattern if our weather had been normal for this area. The flowers were beautiful.

Love this plant! The color of the leaves are grey/green and the flowers are a beautiful purple for the Spring. It remains very attractive once the flowers are gone so it makes a great backdrop plant for later blooming plants. It's also great for hot/humid areas and can go awhile between waterings/rain. If you have the space, it's a care-free must have.

Although I too had heard that it was not advisable to move this plant due to its tap root I was able to successfully move it after it had been growing at least 4-5 years. Actually I hired two young men to dig very deeply and take a very large root ball with it. We replanted it immediately and it has done very well. That was about 8 years ago and it continues to do well with minimum or no care. I do cut it back to the ground in early spring.

We moved into a rental and this large shrub like plant was growing there. Very unusual, but beautiful! Nobody knew what it was. We moved two years later and took a cutting with us. That was two years ago, and it it thriving. We have clay soil and the plant is in a morning sun only location. It didn't bloom last year, but is doing so this year. It has about 12 stalks and is about three feet high now. The original plant that we took a clipping from was about five feet high. Just wanted to let everyone know that you can grow this plant from cuttings.

Beautiful flowers when in bloom and hardy filler plant the rest of the time. Adds winter interest, but also self seeds. Resents transplanting. Blooms in May in my garden.

Definitely need more light - I have two - one is too new to judge yet, and the other one is in more shade - partial from the look of the things. It makes healthy foliages and develops into a large clump but the flowers are fewer, shorter and more "shy" - almost hidden in the foliages. Very touchy about transportation so it's better to get new plants than to transport old speciments. I just enjoy the foliages since that speciment is over 6 years old now while the trees to the south of it have grown taller, blocking the sun and good sunny locations in my yard is hard to come by.

I, too, made the mistake of planting Baptisia in a shady area, and in my zone 5 garden, it's just now starting to sprout again. Do I take the chance and try transplanting it now before it shoots up any further? Last year, it grew quite tall and spindly with just a few blooms. This will be the third year.

I have two plants growing next to my driveway. I noticed the one at the bottom, nearest the street had been stripped of the seed pods while still green. We have deer across the street in a wooded area. I believe they ate the seed pods leaving just the naked stem which carried them.
Another plant to protect from deer if that is possible.

I made a mistake and planted this potentially beautiful plant in a mostly shady spot, and while the foliage looks great, healthy and tall it has yet to produce more than one bloom. Last month I observed a single lovely blue bloom and no more- it was a tease. This is the second year it has been in my garden, so perhaps it's not blooming because it's getting more established. I have a feeling it's the shade though, and I hear this plant doesn't transplant well. It has doubled in size since I first planted it in my garden.

From what I've seen in pictures, Baptisia is absolutely lovely with blooms that look like sweet pea or lupine blossoms, and I love both sweet peas and lupines but neither grow well for me here in NC so I thought I'd give Baptisia a try. I'm going to atte... read more

I adore this plant. It's so easy! I started it from seed 3-4 years ago and this year I have my first flowers.

False indigo loves the sun and the heat and tolerates drought without batting an eye. I fed it with bloom fertilizer and I don't know if that made a difference or not.

Even when it wasn't flowering, the foliage was a beautiful blue-green and had that interesting leaf shape charactoristic of other plants that share it's genus.

My plants are growing very close together at the base and arch out, creating a beautiful fan of flowers.

I don't know if any one else has noticed but the flowers are fragrant, especially at night. Their delicious scent reminds me of the pineapple mandarin cake my mom makes.

A native flowering perennial of the eastern U. S. with an appetite for long term growth and expansion. Quite nice in any perennial garden, but give it lots of space since it can easily cover a square yard in 3-4 years. And it can grow to 4-5' in height. Late spring blooms add a verticle dimension to borders. Very hardy, drought tolerant plants have attractive foliage and flowers. There is also a natural hybrid of the species in white, and another in purple. I have it planted in three spots with one in light shade.

In SE Michigan- this is a wonderful plant!! Although it took one entire season to establish itself. The root needs an entire season to tap itself (I read this). The second season it was absolutely gorgeous.. likes full sun and needs no care - in the fall - all vegetation dies off and blows away like a tumbleweed.
When blooming is over (summertime) it appears to be a shrub - people are always asking about this plant - very impressive.
