Least Favorite Plant: Euphorbia tirucalli

When we bought the glorified shack which is our house, it came with a collection of trees I’d never plant including a twenty foot tall, multi-trunk, Euphorbia tirucalli also known as the “pencil tree.” In most places Euphorbia tirucalli, which hails from tropical Africa, is only a house plant, but here in frost free Los Angeles, the damn thing can grow to massive proportions. Merely cutting a limb of this toxic tree produces d...

Least Favorite Plant: Yellow Oleander (Thevetia peruviana)

Thumbing through a book of toxic and hallucinogenic plants, I finally manged to i.d. the neighbor’s shrub that looms over the staircase to our front door. The popular name given for this plant in the book was “suicide tree”, so named for its use in Sri Lanka, though I’ve found other plants with this same moniker. The scientific name is Thevetia peruviana, and it’s also known as “lucky nut” (can we chang...

Least Favorite Plant: Unkown

This is my first contribution to a regular feature here on Root Simple: the Least Favorite Plant. For me it’s a tie for least favorite between Manroot (I’m sure my adversarial obsession with this plant will compel a future post) and this tree that I have yet to identify (please help in the comments if you know what it is). [update: The Root Simple Community has correctly identified the tree as Osage Orange or Bois d'Arc. Thanks e...

Least Favorite Plant: Asparagus Fern (Asparagus setaceus)

Today, a new feature on the blog: least favorite plants. I’ve always thought that it’s more fun to read a bad review than a glowing one, so why not extend the concept to the plant world? But we’re not going to rant about “weeds”, which Ralph Waldo Emerson defined as, “a plant whose virtues have not yet been discovered.” As active foragers we’ve found virtues in what most people think of as weeds,...

Least Favorite Plant: Ficus benjamina

wers of the City of the Angels. But Schoenholz’s photos do make a persuasive case for what could be termed “outsider topiary.” To be fair, Ficus benjamina is not without some benefits. It’s one of the plants NASA studied for its use in improving indoor air quality. But as the horticultural equivalent of the Nagel print, perhaps it’s time to replace a few of them with its edible cousin Ficus carica. Ficus fans and fo...

Remember to Label Those Jars!

Label, label, label!” This was one of the most important lessons I learned in my Master Food Preserver training. You’ll note, from the jars above, that I’m not very good about this. When were those jars canned and what’s in them? I have no idea. They were probably the result of some late night canning frenzy two years ago. At the time I probably thought to myself, “I’ll label them in the morning.”...

Propagating herbs via cuttings

Mrs. Homegrown here: Say you have one lavender plant, but you’d like to have more. Or your trusty sage plant is getting old and woody and needs to be pulled, but you wish you could save a bit of it and start fresh. One way to accomplish this is to grow new plants from cuttings taken from your existing plant. This is process called taking softwood cuttings. You cut small bits of plant, dip them in a rooting hormone, then baby the cuttings...

Least Favorite Plant: Tree of Heaven

...conditions. In a move that will raise a lot of horticultural hackles, the Detroit Tree of Heaven Woodshop has gone beyond the “if you’ve got lemons make lemonade” phase of their project and has deliberately planted a ghetto palm farm. From their press release: “Detroit Tree of Heaven Woodshop has established its first Tree of Heaven Farm on a vacant Detroit city lot for future harvest. We planted seedlings in beds of car...

Why not plant some Calendula?

Calendula glows like the sun. Mrs. Homegrown here, leaving the composting controversy behind… One of my favorite plants in the garden is Calendula officinalis, aka pot marigold. It should not be mistaken for common marigold, or Mexican marigold, both of which are in the genus Tagetes. Tagetes marigolds are popularly used in companion planting (to ward off bugs in the garden), and for combating nemadtodes in the soil. Calendula...

Failed Experiment: Bermuda Buttercup or Sour Grass (Oxalis pes-caprae) as Dye

...ject all along. I had no burning reason to dye with Oxalis–except that it’s thick on the ground right now. Also, Oxalis is rich in oxalic acid, which is supposed to (cough) serve as a built in mordant, helping the plant dye to bind more easily to both plant and animal fibers. Oxalis theoretically yields tones ranging from lightest yellow to a sort of acid green, depending on which additional mordants you might use. Used straight, it w...
