Eastern Blazing Star (Liatris scariosa)

Question

Q: Mine get really tall and lanky. 4-1/2'. We have to stake them. I think we may be overwatering them too. We have maybe lost two out of seven. . That said, the monarchs love them late August and first part of September. Its September 17 now and they are still blooming a bit but the monarchs seem to be out of here. Or at least the first bunch of monarchs. Have you ever tried cutting them back in mid June? This works for many perennials. They then bloom at a shorter height? Sometimes this makes the cut-back perennial bloom later. Tht would not be good and keeps me from doing so. But sometimes after cutting back in mi-June, they bloom at the same time as always. Seems to depend on the species. Any ideas?

I remember we cut a blazing star species back to about 1 foot a few years ago and it did not bloom that year. I don't remember if it was eastern blazing star, but I don't think any of them will respond well to being cut back.

Cutting them back won't kill them, though, so you could experiment on one next year and see what happens.

The plants can be planted just about any time. During late fall and early spring when the plants are dormant, they will consist of a bulb-like corm with little to no root system. This will make them very easy to plant.

The seeds can be planted November through February. Some may germinate if you wait until March or later, but germination will be better if the seeds undergo a cold, moist stratification period.
