Fall 2013: Lecture: Tuesday and Thursday, 8:05 - 8:55 AM in Johnson Hall Annex C105
Lab: Tuesday 9:10 - 12 in Vogel Plant Sciences Building 43
Review Sessions: Monday 4:30 PM in Vogel 43
Description: Characteristics, identification, nomenclature, ecology, selection, and use of landscape plants, including flowering annuals, deciduous woody plants, and broadleaf evergreens. 
Prerequisites: None. Introductory plant science, e.g. Biology 120 or Hort 202, is recommended.
Hort 231 and Hort 232 do not need to be taken in order.

PLANT LISTS (list of all Hort 231 + 232 plants taught; just Hort 231 plants): 
  1. Annuals
  2. Shrubs with opposite leaves (viburnums) plus Vines
  3. Trees and more shrubs with opposite leaves

  8. Even more trees and shrubs with alternate leaves
  9. Evergreen groundcovers
  10. Evergreen shrubs with showy fruit

Students will become familiar with a variety of native and exotic woody and herbaceous landscape plants. They will understand the biological basis for plant responses to various environmental and ecological factors. They will gain an appreciation for the dynamic nature of plants and the complexities involved in landscape plant selection and use.
STUDENT LEARNING OUTCOMES: By the end of the semester, students will be able to: 
Nomenclature, Morphology, Cold hardiness, Juvenility and maturity, Fall color, Effects on energy use, Genetic diversity, and Human responses to plants.
Required materials:
1. Lohr, Virginia.  2012.  WSU Hort 231 Plant Materials I Identification Cards.

EVALUATIONScores will be posted on Angel at WSU.

10% - Class/lab work and participation (number to be determined; 2 lowest scores dropped)
15% - Homework (6 assignments; no scores dropped)
25% - Class exams and finals-week exam (3 exams; lowest score dropped)
15% - Lab ID comprehensive quizzes (10 comprehensive quizzes; 2 lowest scores dropped)
15% - Lab ID midterm exam
20% - Lab ID final exam - You must earn at least 60% on this exam to pass the course!

  Grades will be assigned as follows, assuming you earn above 60% on the final ID exam. 
93% or more = A
77-79.9% = C+
90–92.9% = A-
= C
= B+
70-72.9% = C-
= B
67-69.9% = D+
80-82.9% = B-
63-66.9% = D

0-62.9% (or below 60% on final ID exam) = F

Homework is due at the beginning of class on the due date. It may be turned in late, but you will lose 1% of the possible points for every day (including weekends) past the due date, unless stated otherwise on the assignment instructions.  You will receive no comments or explanations for your grade on late homework. The last day to turn in late homework assignments is the last class day. Class/lab work assignments or quizzes may NOT be turned in late or made up.  Your two lowest scores will be dropped.
No make-up exams or ID quizzes will be given, because this involves too much extra work for the instructors (work to prepare an alternate, to grade an alternate, and to decide if your explanation for missing is legitimate). The reason that the low scores on exams and quizzes are dropped is to keep you from being unduly penalized for unforeseen circumstances, such as a death in the family, a court appearance, or a faulty alarm clock.  If you miss an exam or quiz, you will receive a zero, unless there are extenuating circumstances AND Dr. Lohr agrees to an alternative arrangement.


You are expected to be a positive, contributing member of the class. Much of the work will be done in groups, so you must act in a manner that helps you and others learn.  Come to class prepared.  Assist other students when you can.  Do not disrupt or prevent learning by others, for example by talking during presentations. Students who do not meet these expectations may be expelled from a class or lab period or from the entire course.

    Regular attendance and participation are essential to doing well in this course. The material to be learned depends heavily on presentations and activities in class and lab. There are no good alternative sources of materials for much of the information covered.  If you miss a class, find out what you missed by asking a classmate.  Obtain any handouts from the instructors.  Do the assigned reading for the class topic and review notes from another student.  If anything is unclear, then ask the instructors to help you.

    For lab, bring your Plant ID Cards each week.  Be prepared to go outside, regardless of weather!   Be prepared to walk rapidly on wet, muddy, or slippery surfaces. Participation includes being ready for the weather, so that you can think and talk about class topics and not about how cold or wet you are. 

    Cell phone use and smoking are not permitted at any time in class or lab, even when you are in lab walking around campus looking at plants. Be sure your phone is turned off.

Integrity: You are on your honor to participate in this class as your own representative and not to pass the work of others off as your own. Academic dishonesty (see: WAC 504-26-010 Definition 3 under Standards of Conduct), in any form, including copying from other students on quizzes or copying from books or web pages on assignments, is unacceptable. If you are caught cheating, you will receive a zero on the involved quiz, exam, or assignment, and you will be reported to your Department and to the Office of Student Standards and Accountability.  If we suspect you are cheating, we may assign a zero or we may choose to give you an opportunity to repeat the activity under conditions of our choosing.

Reasonable accommodations approved through the WSU Access Center (335-3417) are available for students who have a documented different ability. Notify Dr. Lohr if you need accommodations.

“Washington State University is committed to maintaining a safe environment for its faculty, staff, and students. Safety is the responsibility of every member of the campus community and individuals should know the appropriate actions to take when an emergency arises.”  Please become familiar with: WSU Pullman Campus Safety Plan and WSU Emergency Management. Also be sure you have supplied safety alert information at: WSU Alert.

Safety will be enforced in this class.  For example, you may be dismissed from lab if you throw objects such as pine cones or snow balls on lab walks.  I once had to take a student to the emergency room, and I don’t want to do it ever again!
