Golden Alexander (Zizia aurea) is an easy-to-grow perennial that belongs in just about every garden. It’s a host plant for Eastern Black Swallowtail caterpillars and its flat-topped clusters of tiny yellow flowers serve as a great nectar source for a range of native bees, pollinating flies, butterflies, and beetles. Growing 1-3 feet tall, this beauty blooms April through June. It tolerates a range of sun and soil moisture conditions and readily self-seeds. Pair it with Butterfly weed (Asclepias tuberosa), bahama cassia (Senna mexicana var. chapmanii) and dill (Anethum graveolens L.) for an airy garden feel that’s bursting with pops of yellow and orange.
