Plant Overview

A rarely offered, tall prairie plant from North America. Features sunflower-like flowers (to 5" wide) with yellow rays and yellow center disks. Flowers bloom in loose spikes on the upper parts of the plant in summer. 

An interesting point to note is that the leaves of the young plants supposedly orientate themselves north and south. Hence the common name, Compass Plant.

Good height for the rear of the border. Also excellent for naturalizing in prairies, cottage gardens, wildflower gardens or native plant gardens.

Split or broken stems exude a gummy, fragrant-but-bitter resin which was used by Native Americans as a mouth-cleansing chewing gum. 

Please note: due to the nature of this plant (they have little foliage at the base but will grow tall stems when in the ground), these plants will probably not look very impressive when you receive them. Please only buy them if you understand this.

Height: 2m

Common name(s): Compass Plant, Pilot Weed, Polar Plant.

Genus name comes from the Greek name silphion used for a North African resin bearing plant.

Specific epithet means slashed or torn into narrow segments for the deeply cut leaves.

All our plants are supplied in 9cm pots unless otherwise specified. Plants in this size pot establish quickly in the garden and often outpace plants in bigger pots planted at the same time. Our potted plants can be planted immediately, unless otherwise noted, or you can leave them in their pots until you are ready to plant.
The majority of our plants are grown outdoors. This means that they follow their natural growth patterns and are ready to plant at any time of the year. If you order the plants in winter, they are likely to be dormant and died back to ground level, ready to shoot again in spring - just like the herbaceous perennials in your own garden. Very occasionally, in winter, we may indicate on the packing slip that a plant needs to be hardened off before planting out. This will be because it has just come out of a polytunnel. If you have any questions about our plants or growing methods, please feel free to drop us an email.
We grow most of what we sell ourselves, in our nursery in the Buckinghamshire countryside. Our prices include VAT at 20%.
