Bidens. Whether you call them Bur Marigold or Beggarticks or one of a dozen different common names, they are all Bidens varieties. One year an explosion of many bright yellow flowers but another year, nary a one. That is a characteristic that Bidens cernua and Bidens aristosa have in common…along with making awns with multiple points all the better to grab anything hairy or clothed that walks by.

These are the two Bidens I see the most in Van Buren County. B. aristosa and B. cernua both have lovely bright yellow rays. However, they look different enough to tell them apart on the basis of the flowers alone, as shown in this side by side comparison. (Each is discussed separately below.)

The many soft blue flowers shining through the green on the forest floor in early spring just might be a lovely native spring blooming perennial you don’t want to miss: Spreading Jacob’s Ladder (Polemonium reptans).

In Iowa, its common name is just Jacob’s Ladder, as it is the only species of the Polemonium genus native to this state. It also has common names of Greek Valerian and Creeping Polemonium. The Polemonium genus is a member of the Phlox family. The Greek Valerian name is a transfer of a name used for a similar plant in the Polemonium genus in England by Europeans in the Americas.

The name Jacob’s Ladder refers to the leaves. Early Europeans believed they resembled Jacob’s Ladder in the biblical story of Jacob’s dream about a ladder leading to heaven. Though that may be a bit over the top, the little plant is “heavenly,” and the common name has stuck for this species and another two members of the Polemonium genus.

Coralberry (Symphoricarpos orbiculatus) is a deciduous shrub that is native to the Eastern U.S. and much of the Midwest, including Iowa. Its common name describes its fruit or drupe. Other names used for it include Buckbrush and Indian Currant. It is a member of the Honeysuckle plant family. It is more common in southern Iowa, as shown on this map from the Biota of North America Program (BONAP).

Allium canadense is known by many common names: wild garlic, meadow garlic, wild onion, Canadian onion.

Whatever name you use, this wild Allium is the one you are most likely to find in Iowa. It is not a ramp and not a nodding onion. Several other wild Alliums are native to Iowa (including Allium stellatum, which is also called wild onion), but those are not very common.

This map from the Biota of North America Program (BONAP) shows the native range of Allium canadense in Iowa.

Lora Conrad profiles a delicate native plant that is often overlooked.

Cystopteris protrusa (formerly C. fragilis var. protrusa) is variously called Southern Fragile Fern, Creeping Fragile Fern, Lowland Brittle Fern, and Southern Bladder Fern, as well as just Fragile Fern which we will use here. It is a relatively easy fern to identify as it grows in early spring and grows in soil, not on rock ledges.

Once you have seen the structure of the frond, you are likely to recognize it in the future. It is found in oak and hickory woodlands, both high quality natural habitat and significantly degraded woodlands. It is widely distributed in Iowa as documented by this BONAP (Biota of North America Program) map dated 2014.

Lora Conrad features a native perennial at different stages of development.

Great Waterleaf aka Appendaged Waterleaf (Hydrophyllum appendiculatum) is one of only two native Hydrophyllum species in Iowa. The other is Virginia Waterleaf (Hydrophyllum virginianum), which Bleeding Heartland featured here.

Great Waterleaf is a native perennial that thrives in partial shade in rich woodlands. Most photos enclosed below were made on a north facing slope of wooded land just above the Des Moines River in Van Buren County. Others were made in a similar site in Lee County. According to BONAP, it is found more in the eastern two-thirds of Iowa.
