New England Aster Facts and General Description
Is New England Aster Edible?
Apparently there is a long history of Native American tribes using tea made from the leaves or root to treat a wide variety of ailments. Anything from fever, gas or stomach problems. They would use the flowers in pipes and use the smoke for religious purposes, and to treat headaches and a wide variety of other ailments. [1] I don’t consume any part of this plant, and recommend that you don’t either. If it was that good of a medicine, it would be prescribed by a doctor or sold over the counter.General Requirements for How to Grow New England Aster
It prefers full sun, but can take some shade. During droughts you should water this plant, as like other aster family flowers it can start to have lower leaves die out if there isn’t enough moisture retained by the soil. Otherwise, it typically doesn’t need extra watering. Heavy storms can knock it over, especially if it has grown to a large height and is isolated. I will be adding some little blue stem grasses in between my plants to help give it some support, which is what it typically has in the prairies and meadows where it is native. But give this plant some room, and lots of sun and you can expect to have a large, beautiful, stunning late blooming flower that is a pollinator magnet!
Do I need to deadhead New England Aster?
Although deadheading might encourage some more blooming, the most common reason to deadhead is to prevent self seeding.How and When to Divide New England Aster
Late in the fall after the plant has gone dormant, you can divide New England Aster. Every 3-5 years depending on how large it becomes. If you see new shoots forming in the Spring, but none in the center of the plant then that should be an indication that you should consider dividing the plant. So, replant what you’ve cut off somewhere else or give it to a friend!Also…

How to Grow New England Aster from Seed
New England Aster is EASY to grow from seed. Just sprinkle/press some seed into the dirt (pot or ground) and keep moist. So, I just surface sow the seed. Officially I have found that you are supposed to plant it about 1/8″ (3 mm) deep up to 5/8″ (15 mm) deep – which is way too much variation for my liking. I have always found I have the best germination rates when it is on the surface of the soil, or barely covered and kept moist. I just make sure it is misted thoroughly before I leave for work in the morning, and check it again right when I get home. It will generally germinate in a couple of weeks. Just make sure you don’t over-water the seedlings, as they can flop over and die if the stalks are constantly moist.How much water in the pots?
I just pick up the pots in the morning to see if they feel like they have enough water. If they do, then I do nothing. But if they are very light, then I water. If doing this in the Spring or early Summer, while the high temperatures are lower, you don’t need to be as concerned for them drying out if they are in large enough pots. For germination, I use the larger six-packs (never use the 2.5″ deep ones). As soon as I feel I can move them into larger pots as individual seedlings, I do it (note picture below).
If the pots you use are larger, you can expect to have a decent sized plant in 4-6 weeks for planting out in the garden. No stratification required! I sow mine in the spring, and transplant out about 6 weeks later. Direct sowing very early in spring could work fine too – as long as the seed doesn’t get washed out by an early storm. I’ve found that New England Aster can bloom the first year if started/transplanted early enough.
How long does it take New England Aster to bloom if I grow from seed?
If you are early enough, and transplant seedlings by June or even early July, you might get some blooms. But the plant will not be full sized yet, just a couple of feet tall. But in general, with any perennial you grow from seed you can expect full blooms the second year.Purchase Seed

Some Ideas for Growing New England Aster in your garden
New England Aster is from the prairie, or in a woodland clearing. It is a great addition for any kind of meadow garden. But, a mass planting can be nice, but know that it may require some staking if there are large storms/high winds. Alternatively you could plant some Little Bluestem or Big Bluestem grass in between individual plants, to simulate the native habitat. New England Aster is a larger plant that does need water during drought. So, if you plan on having New England Aster grow in a prominent place, where the entire plant is exposed, you should make sure you monitor it during drought, and water accordingly. I generally place my New England Aster flowers in the back of a flower bed, where the lower leaves are hidden.Some nice companion plants for New England Aster
If you are interested in growing New England Aster, maybe consider its smaller cousin, Aromatic Aster. A more compact Aster, it will bloom later than New England Aster giving you more of those beautiful purple blooms, longer into Autumn! Tall New England Asters also work nicely with Echinacea and Rudbeckia/Black-eyed Susans to make a jaw-dropping late summer/early Autumn color display! Thank you for reading this.
