Note: This information page is a work in progress. It should by no means be considered COMPLETE. The archives of info that currently lives on my computer is being moved over to this page so that is more universally accessible. I also add new information as I get asked questions on topics not currently part of my archive. So browse now and come back later. I hope you find this resource useful in your gardening life.

Cultivar Lists

Many plant species have variation in form, size, coloration, etc. When humans have a hand on producing these variations, they are called CULTIVARS (CULTIvated VARiety).

Note: Be aware that not all plants on all lists are always available everywhere. Growers can sell out. It takes time to grow more. It is difficult to always predict consumer whim. Also, sometimes plants fail to meet the expectations. If so, it may be allowed to go the way of the Dodo bird. Growers’ websites are the best place to find out what is available. Then acquiring what you find online can be tricky.

Sources
You may have noticed I have rely heavily on Terra Nova Nurseries for cultivar lists and information. The main reason is they have comprehensive information, and they are LOCAL. This means the information they list is correct for our region and growing conditions. I just wish they grew everything else. If I possibly could, I have found cultivar lists from local sources. But it was not always possible, and though the general information on these non-local sources is valid, remember that in the PNW, plants can grow up to 30% larger than the same plant would grow in another region of the country that also has USDA Hardiness Zone 8. See this post for an explanation of why this is so.

Sedums & Sempervivums
Sewer-Safer Plants – No tree is completely safe to plant over sewer lines, but these are safer than many. Still, none should be planted directly over a sewer line. The document is from Tennessee, but most all of those trees grow here as well.

Blueberry — Good description, imagery, technique, but it’s Maine where it’s significantly colder than here, so their pruning window is wider than ours. Be sure your plants are still dormant when you prune; January or February for zone 8 PNW.

Crimson Clover as Cover Crop to Improve Soil — my handout with links to resources.
Mulch & Compost — My article; mulch & Compost In the Ornamental Garden

Nutrient Cycling (or nitrogen cycle) — This is a term used to describe the process of how organic matter is cycled and recycled through an ecosystem. One of the ways nutrients are recycled is by breaking down fall leaves. Use of fall leaves is the most low-cost and low-maintenance way of supplying mulch and nutrients to your ornamental landscape. I developed a talk with handout page to explain how this process works and why it’s important to understand for all gardeners. View the handout and listen to the audio file at the links below.

Nutrient Cycling Talk — Voice recording about how fall leaves can improve ornamental landscape beds. I recommend viewing the flyer at link in the next bullet item when listening to voice recording. This recording is from one of the typical talks I give to most clients when they ask me about soil, mulch, or compost. It is specific for west of the Cascades zone 8, but I do believe the chemical functions are universal.
Using Leaves as Mulch — How fall leaves can improve ornamental landscape beds. Flyer companion to voice recording.

Sheet Mulching — My article; do it /don’t do it; how-to.
Soil: Deep Down & Dirty — VIDEO — Best soil education I’ve found; not too much ‘science’.

Soil Testing
A & L Western Ag Labs — Standard soil tests. Many other sorts of testing.
EarthFort — Standard soil tests. Microbe analysis.
UMass Lab — Highly recommended by The Garden Professors. Standard test plus organic material.

Toxicity

Some plants are toxic for humans to ingest or touch. Some of the same, or other plants are toxic to certain non-human animals. This is not my area of expertise, but as I come across information that relates to plant toxicity in the ornamental landscape (not related to farm and animal husbandry), I will try to show some resources here.
