I have a similar one---it's actually larger and more impressive than biennis. I believe it's either hookeri or erytherosepala. I've counted upwards of 75 blooms on one plant! It IS a biennial, and I have plants that should flower this summer. I'm really interested in both your Heucheras and your potentilla.

I'm sure that most of the plants on your lists are great and have some wildlife value, Anna, but the ones that jump out at me are - Castillega indivisa/Indian paintbrush - I can only drool at pictures of this beautiful host for buckeyes and fulvia checkerspots since it doesn't occur here, but it's also a good nectar plant for butterflies, and, judging by the looks of the flowers, for hummingbirds, also. It's supposed to be impossible to transplant, but it can be propagated from seeds. If I lived in Oklahoma, I'd order seeds and sow them in a meadow with native grasses - most members of the snapdragon family are parasitic or partially so on grass roots. Centaurea americana - you already have plenty of this - I'd make sure it stays! Antennaria and Artemesia - Both these are host for American ladies, and, if they're as tough as the cudweed in my area, they should be easy to grow. Asclepias, spp. - All of these are desirable, both as hosts for monarchs and the nectar in their flowers, which are real popular with all butterflies. Asters - These give beautiful flowers in the fall that butterflies nectar on, and they're supposed to host pearl crescents. I've planted some rice button asters to add to the naturally occurring asters in hopes of getting PC cats someday. Desmodium - This is the principal host plant for long-tailed skippers in my area - it's VERY easy to grow! Liatris pycnostachya - I just love this beautiful plant, and butterflies love to nectar on the flowers. Tephrosia virginiana/Goat's rue - As far as I know, this plant doesn't host any butterfly, and I've never seen any butterflies or hummers nectaring on the flowers, but it thrives on the poorest, driest, most eroded, pure red/orange clay parts of my property. The rainbow of pastel colors of the flowers is charming, and it might be useful as a host or nectar plant to something - I don't get to the parts of my property where it grows too often. Sherry

Bishops weed and Virginia creeper can be thugs that have adapted to a wide variety of growing conditions and most all questions here about them relate to "how do I get rid of these"? Not something I'd grow even though there is some reported medicinal purpose for them. Evening Primrose self seeds fairly readily in environments it likes, so some do find it a bit of a problem while others do not. Evening Primrose also is reported to be a medicinal plant. Horsetail is an ancient plant also reported to have certain medicinal properties and, again, some find it to be an unwanted plant while others do grow it. I have had it grow in places not much else would. White Avens, "geum canadense", is a member of the rose family and can be an aggressive, and potentially, invasive plant. If any of these get out of your garden and invade a neighbors you may not be a very popular person. kimmq is kimmsr
