Amsonia hubrichtii: The Blue Star with a 5 Star Rating

Enclosed with my Indian Pink seeds from Katherine Shepperly were some Amsonia hubrichtii seeds.  I have Amsonia tabernaemontana already and love it.  The A. taberaemontana is starting to fill in a lower border in mass and is a tough, hardy plant.  I was delighted to receive the A. hubrichtii seeds as they are very noteworthy and will be a great variety to introduce to my yard.  The plant received Special recognition by the Garden Club of America in 2016: 

Three feet wide and high, Amsonia hubrichtii is a clump forming, herbaceous perennial with multiple willow-like, leafy stems emerging from a semi-woody rootstock. This graceful, long-lived, shrub-like plant produces feathery, bright green foliage in the spring that remains neat and attractive throughout the growing season. Terminal clusters of steel blue flowers appear in May and June and pendant, chocolate hued seed heads present well into the fall. The mounding billows of this plant’s foliage turn a brilliant pumpkin orange color in October and November, particularly when grown in full sun. Snow and ice on the stems in the winter provide additional textural interest to the landscape. Suited for mass plantings in sun or partial shade throughout zones 4 to 9, Amsonia is extremely drought and wind tolerant once established and supports butterflies, bees and moths.

As you have probably gathered, two of my favorite reference sites are The Missouri Botanical Garden and the Lady Bird Johnson Wildflower Center .  Reference pages for A. hubrichtii are linked.  The common name is Bluestar and it grows in zones 5-9.  Bluestar will grow to become 2-3' tall and equally as wide.  The powdery bloom appears in May and is a butterfly attractor.  I am hoping the fall foliage will be the same lovely yellow as my other Amsonia.

It's a rainy, foggy day here, so a good day to get these seeds started.  I had an extra milk jug ready and waiting from the day I did the Indian Pink seeds, so it took just a few minutes to put in the seeds, tape the jug closed and set aside.  Our weather is expected to be 70 degrees today, but I know the cold will return soon for the necessary stratification.

Meanwhile I searched ahead for seed collecting and more information and found a nice, new site.  Rob's Plants shows the differences between several of the Amsonias and also shows the seed pod in detail.  The leaves are the main difference between A. taberaemontana and A. hubrichtii (threadlike leaves).  He also lists the 'baggie' method for stratification - it's the same method using coffee filters that we used in starting our milkweed seeds.

Here is a photo of the seeds from Katherine.  You can see them also on the Rob's Plants site above.

And here is a photo of my jug ready to go in the yard.

Two updates on the Amsonia which are doing very well! Photo on the left looks down through the top and shows seedlings emerging.  (April 13, 2017).  The photo on the right shows the top of the jug cut off and lots of growth.  Just one week later.  I will keep them in the jug in the same location for a while longer.  (April 21, 2017).


Healthy plants with lots of roots.
May 28, 2017 The Amsonia h. has prospered and it is time to move out of the milk jug.  I forgot to take a photo of the milk jug to show you, but it was completely full of plants and they were several inches above the top of the jug.  Today, I transplanted directly into the yard into two different spots.  Will let you know how they do.  One spot is in full sun on a south facing hillside but with some moisture from a natural spring in the yard.  The other is in partial sun, still on a south facing hillside but in a much drier spot.  Hopefully the shade at that site will not dry them out too much.

Indian Pink: A 'Top 10" Native Hummingbird Plant

This fall I obtained seeds through the GCA Seed Share site for Spigelia marilandica or Indian Pink. The plant is also called Pinkroot or Woodland Pinkroot.   I was really excited to find these seeds that were posted by Katherine Shepperly of GC of Morristown.

Missouri Botanical Garden Plant Finder, one of my go-to-sources provides a description:  Indian pink is a clump-forming, Missouri native perennial which occurs in moist woods and streambanks in the far southeastern part of the State. Features one-sided cymes of upward facing, trumpet-shaped, red flowers (to 2" long) atop stiff stems growing to 18" tall. Each flower is yellow inside and flares at the top to form five pointed lobes (a yellow star). Flowers bloom in June. Glossy green, ovate to lance-shaped leaves (to 4" long).

This plant is listed as one of the top 10 native hummingbird plants by Operation Ruby Throat.  Be sure and check out their site for other great plants for The Ruby Throated Hummingbird.  I will!

The only difficulty in my yard is moisture, but I hope to find a good site as this is a terrific plant.

I'm a little late getting started, but still plenty of time.  I am going to use the water jug method that our club's Hort Committee has tried in the past.  A full description is provided earlier in our blog in a post titled Winter Sowing Workshop or What To Do With Your Left Over Water Bottles.

It only takes 10-20 minutes to prepare the jug, plant the seeds and tape the jug back up.  On a chilly 35 degree day I set my jug full of seeds outside and will now wait to see what happens. 

Prepared jug is ready and set in a sheltered,
north facing spot in the garden.

Hopefully in May there will be sprouts to pot up, harden off and share with other club members! 

I forgot to show photos of the seeds, so I asked Katherine to take a few of what she had left and to please share her photo.  This is how the seed looks when collected.
Tiny, tiny seeds!  Read below for help the collection process.

I also was interested in how and when to collect the seeds.  Dave's Garden has some great information on this plant.  One of the comments posted on their site led me to Univ. of Kentucky College of Agriculture that has an excellent and very specific instruction sheet on seed collection and propagation.  Most collectors indicate that the best method is to place a small bag over the seed pod so that they will drop into when ready.  You can see from the above photo how small the seeds really are, so that suggestion is a great one.
