Applying what I learned in Intro to Horticulture

On this page, I have revisited many of the topics we covered in Introduction to Horticulture taught by Darlene Pickell at UCLA Extension (Summer 2011) and sought to apply them to our property.

Climate Zone Designation for our Property:

  • American Horticultural Society Heat Zone Map:  Zone 8
  • USDA Cold Hardiness Map:  Zone 9b/10a
  • Sunset Western Climate Zone Map:  21

Examples of plants in the garden illustrating differences between biological classifications

(applicable photos are below the caption in each case)

Angiosperm: flowering plants that produce fruits and seeds within, such as this Rhamnus californica with seed bearing fruit just emerging (August 2011).

Gymnosperm:  cone-bearing plants, such as this fallen cone from Pinus halipensis
Monocot:  Angiosperm that is non-woody, showing parallel leaf veins and flowering in petal clusters of 3s. The first example is Liriope muscari.  The second photo below contains two examples — Agapanthus orientalis and Clivia miniata.

Dicot: Angiosperm that is typically woody, showing branched, reticulated leaf veins and flowering in petal clusters of 5s.  The first example is Arctostaphylos viridissima (Manzanita).  The second example is Ceanothus ‘Julia Phelps’.

Leaf Type: Simple, as on this Ribes viburnifolium

Leaf Type:  Pinnately Compound,as on this Fraxinus [?]

Leaf Type:  Palmately Compound [?], as on this Acer palmatum

Leaf Type:  Double Pinnately Compound, as on this Nandina domestica

Leaf Arrangements:  Whorled, as in this Pittorsporum tobira variegata

Leaf Arrangement:  Opposite, as in this Mahonia repens

Leaf Arrangements:  Alternate, as in this Rhamnus californica (coffeeberry)
See the Soils Analysis sub-tab wherein we summarize the results of 10 soil samples taken throughout the Property.  Observations regarding the findings are at the bottom. Here is the link:  Soil Analysis
Based on the soil analysis, and the particular needs of plants in different parts of the property, we put together a fertilizing plan.  Here is the link:  Fertilizing Plan
Pests and Problems:
Our observational skills in this regard are developing.  We’ve started to notice issues such as those taught in class.  See the following link:  Pests and Problems

    Great site! If you can recommend good plants and gardening techniques to withstand THE WORST DROUGHT SINCE 1985 IN TEXAS, please let us know.

    Hi Michael,
    Robert here, from our UCLA Intro to Horticulture course. I FINALLY made it to your site. And I love it! Nice job, very elegant and informative. Reading your “learned lessons” above felt like a quiz review (LOL). Hope you are keeping well.

      Robert – Great to hear from you. Appreciate the positive feedback. Forcing a blog to be a website is challenging. Hope to see you in another class.
