Categories of Plants

I asked chatGPT to give me a list of the standard categories of plants used in horticulture and landscaping. It gave me the following list. I will be adding links to examples of each category as I publish them. 

This list is useful for expanding your plant id and knowledge. 

Note: The above infographic was also generated by ChatGPT, and as you can see, is not exactly perfect. A work in progress. 

Standard Horticultural Categories

1. Trees

• Deciduous Trees – Lose leaves in winter (e.g., maples, oaks, cherries).

• Evergreen Trees – Keep foliage year-round (e.g., pines, cedars, firs).

• Ornamental Trees – Grown for flowers, shape, or seasonal interest (e.g., dogwoods, magnolias).

• Fruit & Nut Trees – Apple, pear, hazelnut, chestnut.

2. Shrubs

• Evergreen Shrubs – Provide year-round structure (e.g., boxwood, rhododendron).

• Deciduous Shrubs – Lose leaves in winter, often with seasonal flowers (e.g., lilac, hydrangea).

• Flowering Shrubs – Grown primarily for blooms (e.g., spirea, camellia).

• Berry-Producing Shrubs – Wildlife attraction (e.g., currants, blueberries).

3. Perennials

• Plants that live more than two years.

• Herbaceous Perennials – Die back to the ground each winter but return (e.g., hosta, coneflower).

• Evergreen Perennials – Retain foliage year-round (e.g., hellebore, certain ferns).

• Flowering Perennials – Daylily, black-eyed Susan, lupine.

4. Annuals

• Complete their life cycle in one growing season (e.g., marigold, petunia, zinnia).

• Used for seasonal color and bedding displays.

5. Biennials

• Complete their life cycle in two years (e.g., foxglove, hollyhock).

• Flowering occurs in the second year.

6. Groundcovers

• Low-growing plants that spread to cover soil (e.g., creeping thyme, vinca, ajuga).
