The blooms are large, airy and slightly fragrant with panicles about four inches wide. This plant is native to North America and grows most commonly in the central and northeastern United States and the southeastern parts of Canada.

How To Plant Queen Of The Prairie
Queen of the prairie is not native to the area where we live, in Nova Scotia Canada. It does grow well in this location.
Queen of the prairie can be dug and divided in late summer or fall.
If transplanting from division in cooler zones, it is important to make sure that the plant has some growing time before the first frost, so that it will have time to get established and set roots before the ground freezes.
Here in zone 5b we have best success with plants planted before August, as sometimes the frosts will heave plants through the winter if they have not established good root systems before the freeze.
Soak Roots Prior To Planting
We received our Queen of the prairie plant via mail order. The plant was just starting to sprout, as was evidenced by the small green growing tip.
We soaked the roots for 30 minutes prior to planting, as per the packet instructions. It’s something that I usually do anyway with most plants that come by mail order.
The brief soaking helps to rehydrate the plant and stimulates growth.
The Queen of the prairie was planted at a depth where the crown was just below the soil surface.
Within a week the small first leaf was visible above the soil.
We only planted one Queen of the prairie plant into our garden. Queen of the prairie is fairly fast growing, and it will fill out and provide a nice clump within a few years.
Some gardeners plant Queen of the prairie in small groupings. The plant when mature can be up to four feet wide, so space accordingly.
Each plant will spread underground via the root system, and will form a mounded clump.
When To Plant Queen Of The Prairie
Plant in the spring if received via mail order or purchased at a local nursery.
If planting from a division, it is best to divide the plants later in the summer, and then plant at that time. Make sure that there is some growing time before the frost sets in the ground.

Sun Or Shade?

Queen of the prairie prefers moist soil.
It is important to consider the potential height of this wonderful plant when deciding where to plant it. If you are planting in a sunny location with moist well drained soil, the potential for an eight foot plant is pretty good.
To be safe, the best location would be at the back of the border, or in the centre of a garden bed.
The other issue is staking in high wind locations. The stems are very strong and rarely need staking, however in high wind locations this may be necessary.
