Why These Plants?

B1 Plants & Schedules
About this lesson ▾

A plant list is not a shopping list. Every row on it answers a question a client asked, even when the client never said the question out loud.

Warm-up · 5 min

Why did you choose these plants?

Think of a planting choice you made on a real project — one specific plant, one specific spot.

  • What did the client actually ask for?
  • What about the site made that plant the right choice — or the wrong one ruled out?
  • Did you explain your reasoning to the client, or just deliver the plant list?
Teacher note Listen for whether the reasoning has a real chain — client wanted privacy, the spot gets afternoon sun, therefore an evergreen screen — or whether it is just a list of plants with no stated connection between them. That chain is what this unit builds.
Predict

Before you think about your own choice, predict:

Input & Noticing · 10 min

What a plant schedule actually has to answer

Four questions, four kinds of column

QuestionColumn typeExample
What is it, exactly?NameLatin_Name, Common_Name
How big does it get?SizeSpread, Height, Mature_Height
How far apart do they go?PlacementSpacing
What does it need to survive?RequirementWater_Range, Light_Range

Every one of those four questions is really a client question in disguise. "How big does it get" is "will this block my view in five years." "What does it need" is "will this survive if I forget to water it." Reading a schedule fluently means hearing the client question behind each column, not just the column name.

Discovery Check

Check what you just read.

1. Which client question does the "Spacing" column answer?

2. What does the card say fluent schedule-reading actually means?

03
Focus on Form · 8 min

Want, constraint, choice

The justification chain

LinkExample
Client want"I want privacy from the neighbours."
Site constraintThe fence line gets full sun and needs a screen at least 8 feet tall.
Plant choicePodocarpus — evergreen, reaches 8–10 feet, tolerates full sun.
The Chain

Put these three links back in the order the justification chain actually runs.

Lexical Matching

Match each term to what it means. Click the term, then its meaning.

Keeps its leaves year-round
Loses its leaves in a season, then regrows them
Survives on low water once established
Planted alone as a visual focal point, not in a group
Low, spreading planting that covers bare soil
MCQ Reading

Choose the best answer.

1. A client says "I want privacy from the neighbours." What is this in the justification chain?

2. Which column on a schedule most directly answers "will this survive if I forget to water it"?

3. Why does reading a schedule well mean hearing the client question behind each column?

Baseline Performance · 15 min

Justify a real choice

Your Day One marker for this unit.

Task card

One planting choice from your own work, explained from scratch

State the client want, the site constraint, and the plant choice — in that order, out loud.

  • All three links have to be explicit, not implied.
  • Name the actual plant, not a category ("an evergreen shrub" is not enough).
  • Keep it. Lesson 8 comes back to it.
Classify the Chain

Match each real example to the link in the chain it represents.

Client want
Site constraint
Plant choice
Teacher note Note whether all three links appear, and in order. Most designers at this baseline state the plant choice confidently but skip stating the constraint explicitly — it stays in their head, not in their sentence.
06
Feedback & Reflection · 5 min

All three links?

  1. Did you state the want, the constraint, and the choice — or did one get skipped?
  2. Did you name the actual plant, or a category?
  3. Would a client have understood why, not just what?
One More Check

One more check before you move on.

1. If a client would not have understood "why," what is most likely missing?

Wrap-up · 5 min

Before the next lesson

Homework. Bring a plant schedule from your own work, or a list of five plants you have specified before, from memory.
