One reason I like arboreta and conservatories is the signs. My memory for plant names is sieve-like, so it’s good to be able to look down and find out the name. The age of digital cameras has made it even easier to take notes based on the signs.

For instance, I know this is a W.B. Clarke Anise Magnolia (Magnolia salicifolia). It grows at the Klehm Arboretum & Botanic Garden in Rockford, a fact I documented on Saturday.

It isn’t a Southern magnolia (Magnolia grandifora). Good thing, since Rockford isn’t remotely in the South. I’d never seen magnolias quite like this, but then I’ve read there are many kinds.

Apparently W.B. Clark was an early 20th-century hybridist working in San Jose, California, traces of whom are accessible to casual Googlers. He seems to have developed some plant varieties that are still with us, such as the Anise Magnolia, whose ancestors are from Japan.

The arboretum sported a few other attractions, such as a pleasant water feature —

–and a maze of bushes. Not a very large one, and easily navigable to a child of 11 and middle-aged householders. The most interesting part wasn’t the maze itself, but the analemmatic sundial within the maze, such as we once ran across at Fermilab.

I stood on the May stone and my shadow told the time more-or-less accurately, accounting for Daylight Savings Time.
