![]() When food is very limited, they’ll even snack on twigs and other woody plants.Īs long as it’s not meat, deer will probably eat it. In the wild, they’ll eat weeds, grass, flowers, seeds, nuts, fruit, vegetables, and pretty much anything else they can get their mouths around. ![]() Naïve insects will visit the wrong flower before learning where the nectar and pollen can be found.That’s a common question among farmers and deer enthusiasts, and you might be wondering that same thing.ĭeer aren’t picky animals. 63 Furthermore, it has been shown that insects must learn the difference between colors. In the intervening 200 years, ecologists have confirmed these speculations. 63 At the same time, Müller postulated that the color change directed the pollinator away from the fertilized flower, which no longer needed its services, to unfertilized flowers with ample rewards of nectar and pollen. Nevertheless, a number of unrelated species have evolved a color change, leading a colleague of Charles Darwin, Fritz Müller, to speculate that retention of the petals enhances the color presence of the plant and hence the distance from which it can be recognized by a pollinator. ![]() Most plants drop their petals immediately since the pollinator-attracting job of the petals is no longer needed. The change in flower color from yellow to orange follows pollination. 34ĭeerweed is drought deciduous, but the stems contain chlorophyll allowing the plant to continue to photosynthesize and grow. 34, 35 Deerweed is gradually displaced as the pre-fire vegetation recovers. ![]() 4, 13 Thus deerweed aids soil recovery by replacing nitrogen lost during the fire. 26Like many members of the pea family, the roots of deerweed contain symbiotic nitrogen-fixing bacteria that transform atmospheric nitrogen into nitrogen compounds that can be used by other plants. 14 Deerweed often dominates the second year after a burn. 48Īlthough deerweed rarely survives a fire, germination of the seeds is stimulated by heat 34 leading to rapid post-fire colonization. glaber, distinguished on basis of relative length of wings and keel. For many years our species of Acmispon were placed in the old world genus Lotus and they are still found with this name in less recent publications. There are six species of Acmispon reported from the Reserve 48 including the endangered Nuttall’s lotus ( A. Other members of this family found commonly in the Reserve include ocean locoweed ( Astragalus trichopodus), collared lupine ( Lupinus truncata) and chaparral sweet pea ( Lathyrus latiflorus). 44 In addition to peas and beans, the Fabaceae includes peanuts, licorice, acacia and clover. The pea family is the third largest family of angiosperms in the world and one of the most economically important, often associated with developing societies. Many members are associated with nitrogen-fixing bacteria in root nodules. Most members of this family have a flower similar to a pea or sweet pea flower. 4 Members of this family are characterized by their fruit, which is an elongated pod with seeds attached along one seam and which usually opens along the opposite seam. 11ĭeerweed is a dicot angiosperm in the pea (legume) family (Fabaceae previously called Leguminosae). Seeds are an important food for many birds and small animals, which may be important dispersal mechanisms. Unlike most related plants, the pod does not open to release the seeds. 1įruit is a two-seeded pod 5/8 inch (1-1.5 cm) long, somewhat curved upward and tapering to a long beak. The main bloom period is March-July, but some flowers may be found throughout the year. 4, 26 Clusters of two to seven flowers attach directly to stem at a single point, and many clusters along the stem open about the same time. There are ten stamens, nine united and one free, and a single pistil. In turn, the keel encloses the male and female reproductive structures. Two side petals (“wings”) are directed forward, enclosing or concealing the remaining two petals which are fused lengthwise into a “keel”. The upper petal is large and flares upward forming the “banner”. They have the bilateral shape of a typical pea flower. Leaves may be shed during the dry summer.ĭeerweed flowers are 1/4-3/8 inch (7-12mm) long, yellow, aging to orange. The hairless or sparsely-haired leaves usually consist of three oval leaflets, 1/4-3/8 inch (6-15 mm) long when more than three, leaflet arrangement is pinnate. When not crowded, the plant assumes a hemispherical shape, usually less than three feet (1 m) high. Deerweed is a shrubby perennial with wiry, green branches arising from near the base of the plant.
