How to grow golden Alexander – for a native North American wildflower with electric acid-yellow blooms that pollinators adore

Native to eastern North America, golden Alexander, or Zizia aurea, is an impressive wildflower that is prized for producing acid-yellow umbels during spring, usually around May and June. And, not only do they look good, but pollinators love this spring-flowering wildflower, including bees and butterflies.

In its native range, golden Alexander grows in wild meadows and wetlands, although it can thrive in backyard planting schemes that veer towards the wild side. If you enjoy loose, freer prairie-style planting, this wildflower is surely one to add to your plot.

So, if you are wondering how to plant a wildflower meadow in your backyard, golden Alexander is a good species to start with. This easy-to-grow plant will fill your space with color and wildlife – what's not to love?

How to grow golden Alexander

Yellow flowers, like golden Alexander, can inject life into planting schemes, particularly during springtime, when daffodils and dandelions are a common sight. Here's how to grow golden Alexander, including expert tips from a pro gardener.

Growing habits for golden Alexander

'Golden Alexanders are tough, US-native perennials that brighten up garden borders,' says Reese Robbins, garden expert and creator of Just Pure Gardening.

'They’re perfect if you are looking for wildflower garden ideas,' Reese continues.

'Hardy down to zone 4, they require little maintenance once established, and, what's more, they are self-seeding flowers, so with any luck, they will spread across the wild pockets of your yard.'

'Sow seeds in fall or stratify indoors (cold/moist for 60 days) before spring sowing.

'Once sprouted, they prefer full sun to light shade and tolerate a range of soils, ideally moist, loamy, and well-draining,' Reese says.

Golden Alexander seeds are now available from Amazon.

Care guide for golden Alexander

Soil: Golden Alexanders do best in a neutral to fertile soil, so it is a good idea to spend a little time mulching to enhance the richness of your borders. Try this organic mulch from Back to the Roots, available now via Walmart. However, if you have clay soil or even poor soil, do not fret, this wildflower can grow in most situations.

Light: In general, this short-lived perennial thrives in full sun, but will tolerate part-shade. However, to enjoy the best floral show, I would recommend planting in borders or meadows with at least four hours of sunshine.

Watering: Deep watering is recommended during the first few weeks to help your new plants settle. In their native range, they enjoy consistently moist soil (typically thriving in boggy and even waterlogged soil), so a little water will go a long way in helping your golden Alexander plants to thrive.

Fertilizing: There is no need to fertilize golden Alexander flowers. As with other wildflowers, they can usually access what they need from the soil. Do not be tempted to apply excess feed, which can do more harm than good.

Pruning: Golden Alexander does not require much management or pruning. All you need to do is cut your perennial down to the base after it has flowered, sometime in summer, once the foliage and flowers have faded. However, the seedheads can be left if you are keen to encourage self-seeding in your yard.

Toxicity: Golden Alexander is considered non-toxic, although the roots, if ingested, can cause sickness, so keep an eye on pets who might be tempted to dig around your plants.

FAQs

Can I grow golden Alexander flowers in pots?

'I would suggest planting Zizia aurea alongside other plants that attract pollinators,' says Reese. 'Pair it with milkweed, purple coneflower, or liatris to support wildlife garden ideas with a layered native border.'
