Apples and Oxalis

By Nan Sinton, Director of Programs

Is it apple cider or apple pie? The scent of sweet shrub (sometimes called strawberry bush), Calycanthus floridus, fills the air in spring with what reminds me of ripe apples. The dark red blooms are about the size of a large strawberry and a powerful presence at the edge of my spring woodland. (If you’d prefer a pale yellow blossom then look for the selection ‘Athens’.) Clean glossy deep apple green foliage, adaptable to part shade to sun, this native of deciduous woods from Maryland to Florida and Mississippi is perfectly comfortable in more northern gardens (Zone 5, maybe 4, to 9). Calycanthus has an Asian cousin, the beautiful, though unscented, Sinocalycanthus chinensis. Its’ flowers remind me of a tiny single peony –elegant and tough.  And, yes, I’m growing Sinocalycanthus too. My plant started as a tiny mail-order rooted cutting. Now, three years later, it is a sturdy 4’tall shrub and blooming profusely. The late Dr. J.C. Raulston made a number of crosses between Calycanthus and Sinocalycanthus, most notably ‘Hartlage Wine’ (Calycanthus raulstonii ‘Hartlage Wine) with large deep wine red blooms. Now there is another outstanding new hybrid, Calycanthus ‘Venus’ from the propagation work of Dr.Tom Ranney. It has blooms as large as those of Sinocalycanthus and a delicious fragrance. Just imagine collecting all of these--the possibilities for a garden display are amazing.

Less amazing, in fact daunting, is the world class crop of oxalis that has appeared in my beds and borders this spring. What should I do? I’m all for 4 leaved clovers and shamrocks but I have oxalis by the zillion. I know that hand weeding may cut down on the population but all those tiny thread like roots will quickly re-colonize the area. Should I smother it with newspapers and mulch? Try very careful weed wiping with glysophate? Suggestions welcomed before the oxalis starts having territorial ambitions and heading for the house!
