Gardeners' Notes:

Positive plant_it On May 27, 2011, plant_it from Valparaiso, IN wrote:

Native to the U.S. and Canada.

The pollen or nectar of the flowers attract many kinds of insects, including long-tongued bees, short-tongued bees, wasps, flies, butterflies, skippers, beetles, and plant bugs. Examples of more frequent visitors include Little Carpenter bees, Nomadine Cuckoo bees, Green Metallic bees and other Halictine bees, Eumenine wasps, Tachinid flies, and Thick-Head flies. The caterpillars of Schinia lynx (Lynx Flower Moth) eat the flowers and seed capsules, while Lygus lineolaris (Tarnished Plant Bug) sucks the plant juices. Among mammalian herbivores, deer and rabbits occasionally consume the leaves, stems, and flowers.

Preference is full or partial sun and moist conditions.

Identifying features of the species, is hairy leaves, pinkish tint to blooms, and flower buds hang low before flowering. Other species of Erigeron have these features too, but this species excels at each. In my area this species flowers in early spring. Other species of Erigeron flower later. (Erigeron pulchellas) supposedly has more hairy leaves/stem, but it spreads underground, whereas (E. philadelphicus) does not.

I've seen this species mentioned as a possible host plant for the Northern Metalmark (Calephelis borealis).

Fleabane Daisy, Erigeron philadelphicus is native to Texas and many other states. All wildflowers are a joy to find growing in their natural habitat and this one is very attractive to bees and butterflies.

A very common weed or wildflower whichever you'd like to say. About three feet tall, pretty but weedy - not necessarily suitable for a garden unless in a hybrid form. Good in wildflower gardens but can be invasive. You can tell the difference between this and Erigeron annus as Erigeron annus has toothed leaves and Erigeron philadelphicus does not (it has smooth leaves :)
