The Growth Cycle of the Bluestar Flower

Amsonia flowers are perennial, meaning that the plant lives for more than two years. Bluestar is a spring ephemeral. The leaves will appear when they feel like it. Once they have grown to be large and green, flower buds will appear at the tips of the stems. Then, at last, beautiful blue star-shaped flowers will emerge from the buds and bloom for about three weeks in late spring or early summer. WiThelant goes through its final growth stage bewith flowering complete fore beginning a dormancy period in late autumn (fall). Plant parts above ground die back after temperatures drop below freezing in colder climates; however, roots grow underground until soil temperatures drop too low.

How to Grow Amsonia Flowers

The Amsonia are incredibly hardy plants that can be grown in almost any soil type, although they do best in soil that drains well. You can grow them from seed or purchase young plants from nurseries and garden centers. If you want to increase the plant in your garden, there are two ways:

  • In the springtime, start by digging a hole about an inch deep and filling it with water. Make sure the dirt is loose so that they aren’t suffocated by mud when you plant the seeds. If necessary, loosen up some of the surrounding soil before planting.
  • Once planted, place a few inches of mulch around each seedling to retain moisture while preventing weed growth until they have started growing on their own. Dig up an area around each seedling’s root ball so that there is space for new roots to form without being crowded by neighboring plants. Plant two or three seeds in a row about eight inches apart along your path to always be something growing at all stages throughout the season!

  • You can also plant seeds indoors if you’re worried about frost damage outdoors (which will kill most varieties). Fill small pots full of potting mix or peat moss – make sure these containers have drainage holes! – then, put one Amsonia seed into each vessel. Place these containers under fluorescent lights for 12 hours every day until germination occurs (about three weeks). Keep watering them regularly and transplant them outdoors when they reach maturity (usually after four months).

Pruning and Maintenance of Amsonia Flowers

Those looking for a low-maintenance plant will be pleased to see that maintenance of this flower is straightforward. After the flower heads have dried, remove them, then prune the entire plant back to the ground. When pruning Amsonia, cut the enwholelant back to about two inches tall. Each year after flowering, prune your blue star flowers down to keep them looking neat and compact. This can be done in early spring or late fall.

You can propagate Amsonia flowers by seeds or division of the root ball, which should be done every few years. It is usually best to divide them as soon as new growth appears so that you can separate the plant into several smaller bunches at planting time.

Pruning is not required for these plants, but you may wish to cut them back after flowering has finished for the season if you have space issues with nearby perennials that need room to grow or spread out naturally during the growing process season.
