Plant Story--Distinctive Apache Plume, Fallugia paradoxa

Apache plume (Fallugia paradoxa, rose family, Rosaceae) is a native shrub of the southwest, found from Colorado and Texas west to California and Arizona and in neighboring areas of Mexico. It is a pretty shrub with white flowers and distinctive clusters of long-lasting cream or pinkish fruit resembling plumes.

Plant Story--Cinquefoils, Potentilla

"If any man will ask any thing of a king or prince, [cinquefoil] giveth abundance of eloquence, if he have it with him, and he shall obtain that which he desires," wrote Albertus Magnus in the 13th century. Well, not really. Albertus Magnus (d. 1280, biography) was a real person, a famous medieval German scholar, but The Book of Secrets of Albertus Magnus was an anonymous work of folklore and superstition that appeared in the 16th century. But, clearly, cinquefoil was considered a powerful plant.


Cinquefoils were medicinal and magical plants in Europe. They are a group of plants in the rose family (Rosaceae) with pretty five-petal flowers, usually yellow, and distinctive leaves with five lobes like a hand. The common name, cinquefoil, means five-leaf in French. Old English names included five-finger grass (grass meaning "plant" in this context), but some species had distinctive names, for example silverweed and tormentil.

Plant Story--Shrubby Cinquefoil

shrubby cinquefoil, Dasiphora fruiticosa

Cinquefoils are cute little flowers, usually yellow, in the rose family, Rosaceae. Traditionally they were in the genus Potentilla. Shrubby cinquefoil of the northern and western North America (see USDA map link) was for many years called Potentilla fruticosa. It is easily distinguished from the 68 native and 8 introduced species of Potentilla in North America because it is the only woody shrub, not a non-woody herb. Then, some years ago, DNA and other evidence indicated that shrubby cinquefoil and the other cinquefoils that are shrubs (11, all from Eurasia) were pretty different from other cinquefoils, so they were reclassified into another genus.

Plant Story--Flowering Shrub of Spring, Amelanchier, Serviceberry, Saskatoon

A shimmer of white in my front yard: the serviceberry is flowering!

serviceberry, Amelanchier alnifolia


You might call it shadbush like my parents did, or saskatoon, as they do in Canada, or juneberry--the name you might see in the supermarket--or more regionally shadblow, sarvis or sarvisberry, sugarplum, wild-plum or chuckley pear.

All of these are names for native Amelanchier species, mainly A. alnifolia, though there are approximately 10 species native to North America (link: USDA plants)

Botany Rules 3: Why do Botanists Always Tell You the Plant Family?

        People writing about plants are forever sticking the plant family into the discussion.

    That intended to be helpful. There are at least 300,000 species of land plants. Nobody knows all 300,000. They are organized into classes made of orders, made of families, made of genera and species. Most of the land plants, about 280,000 species, are flowering plants, angiosperms, and are in the same class. There are approximately 60 orders, 400 families and 12,000 genera of angiosperms. Orders are so big that they contain very diverse plants. For example the order Asparagales includes orchids, onions and century plants. Writers include the plant family in hopes that you’ll know one plant in the family mentioned and it’ll give you a decent guess what the plant described is like.

  
      Here, for example, are capsule descriptions of a few major plant families, not intended to describe their characteristics as much as to prod your memory of them. Plants differ and botanists group them based on those characteristics, so plants in the same family share important characteristics while those in different families seem, and are, different.

   For example, members of the Rose Family have a ring of five petals around a center and produce a usually fleshy fruit with a few hard seeds inside. Lots of them are shrubs or small trees. Members of the rose family, in addition to roses, are apples, plums, apricots and pears.
