This is my second year with Golden Alexanders growing in clay soil, partly shaded. They've done well. Nice flowers, nice foliage (tall). Flowered in the spring, but now (July) I have new flowers on new growth. Seedheads are attractive.

Posted in August 2008: I really wanted to grow this, but rabbits and groundhogs have eaten it over and over. I planted bulk seed in a flower bed in sun, and many plants are still alive after all the abuse from the small mammals, but they've never gotten big enough to flower or thrive before being eaten off again.

Updated May 2014: What seemed like one small plant survived and began to prosper. Now an entire corner of the bed is covered in Golden Alexander. Not necessarily invasive, but maybe a bit aggressive? Still I'm glad that it survived and has prospered.

Likes boggy areas and wet areas - will grow in partial shade - can only be found in specialize wildflower nurseries. The reason for this is that it have less (by the avearge person) beauty - it have flowers that look like a yellow Queen Anne Laces but smaller in size. Otherwise this native will add diversity to a open wooded wetland (it doesn't compete well with cattails and other aggressive water plants.)
