A native perennial I’ve loved since the moment I heard about it is the Compass Plant – Silphium laciniatum. I think my attraction was originally to the common name and then its striking height. It grows to about eight feet high in my garden some years, and its large basal leaves are said to point mainly north and south, to catch as much direct sunlight as possible. The leaves take up a lot of space! Although it’s said to have a long taproot, and is hard to transplant (I started mine from seed), I’ve found it to be not extremely drought tolerant. This is a great plant if you’re looking for a striking, architectural perennial, and have at least a square metre (about 10 – 12 square feet) to spare, in full sun, in soil that remains moderately moist to dry – just not too dry!

Did you feature this earlier? This is not the first time I saw it.

This is wonderful. I often see Silphium radula but this one’s less common, even though it is native to the eastern part of Texas.

I’ve never seen S. radula – not surprising I guess. My S. perfoliatum is just starting to bloom – it’s having a good year too!
