Toxic Plants

Surprise Seedling: Nicotiana Glauca

JM Perez By JM Perez2 min read757 views

A couple of months a ago, we purchased a few Lavender trees from Lowe’s. Every now and then I will find a freebie in the pot while transplanting the plant, and this time wasn’t different. I found a tiny seedling with large bluish-green leaves at the base of the Lavender plant and decided to let it be and see what it grows into (I am not fond of plants with large leaves, unless it’s a Magnolia plant). Today I found out that the plant is the seedling of Nicotiana Glauca. Though non-native to California, it is classified as invasive here.

Nicotiana Glauca, also known as Mustard tree, tobacco bush, tobacco plant, tobacco tree, tree tobacco, or wild tobacco is an evergreen shrub or small tree native to South America. The plant can grow up to twenty (20) feet and is short-lived. It is used as an insecticide and smoked as a stimulant by smoking the plant or chewing it. This plant contains the toxic alkaloid nicotine, and can cause blood pressure, cancer, peptic ulcers, tremors, joint pain, anxiety, depression, drowsiness, dizziness, vomiting, diarrhea, trouble sleeping, headaches, respiratory failure, etc … and death.

According to Tropical.theferns.info (Useful Tropical Plants Database), Nicotiana Glauca has a variety of medicinal uses such as:
– Applying a poultice of the leaves to cuts, bruises, swellings and other wounds.
– Applying a poultice of the leaves to remove the pus from scrofulous sores or boils.
– Using an infusion of the leaves as a steam bath in the treatment of rheumatism.
– Applying warmed leaves to the head relieves headaches, on the throat to relieve pain and put in shoes for painful feet.

Though ornamental, the plant is said to pose a threat to biodiversity by competing with native species for resources and displacing native plants. The plant is propagated by seeds and flowers emerge around one year after germination . It is said that in its native range, Nicotiana Glauca is pollinated exclusively by hummingbirds. All parts of the plant are poisonous.

Given the information I obtained about this plant, I know I should get rid of it. However, given the fact that I have never seen a Tobacco tree (and out of curiosity), I will keep it for a year, just until the first flowers emerge. I will relocate the seeding this weekend to the end of my property and watch it grow from a distance, until it’s time to bid it farewell.

Happy and safe gardening!

Happy New Month

JM Perez By JM Perez2 min read757 views

It’s a new month and the weather has been at its best since the beginning of the year. It rained a little today, more like sprinkles to be precise.

What has everyone been up to? Well, I have enjoyed the company of my Mother who I don’t see often and her delicious cooking. I have been weeding, lending a helping hand to my neighbors and just recently, began tending to the gardens. I have significantly reduced the amount of Gaura Lindheimeri in the front garden and replaced them with Salvia Greggii Red. I planted some African Iris (Dietes Vegeta) and I am currently looking for a few companion plants.

The majority of the bulbs are emerging from the ground, a few trees are starting to leaf out. What’s blooming in the garden? So far only two plants; the Purple Leaf Cherry Plum trees and the Gopher plants (Euphorbia Rigida).

Euphorbia Rigida, which were a gift from a neighbor, are currently blooming. The first time I saw the plant, I thought it was either an overgrown weed or a rare cactus species. Also known as Upright Myrtle Spurge, Silver Spurge and Gopher Plant, these hardy yellow flowering plants are drought tolerant and self-seeding (remove spent flowers to prevent self-seeding). The plants attract bees, butterflies and hummingbirds; and susceptible to aphids, nematodes, spider mites, bacterial and fungal diseases. It is however, deer and rabbit resistant.

Euphorbia Rigida are a wonderful addition to desert landscaping. The attractive succulent-like plant features erect stems with narrow leaves and evergreen  foliage that are flushed with red in Spring and blue-green in other seasons. The flowers are bright yellow-green in Spring with orange nectar gland (the color can vary). The plant can be propagated either by seeds, cuttings or division. Be advised that this plant is a deadly beauty, as all parts are highly toxic if ingested and the milky sap may cause irritation to the eyes and cause skin rashes. Wear gloves at all times when handling the plant.

Somewhere in my backyard, I found two pairs of Lizards in an empty terracotta planter. I am not sure if they are all resting in there or perhaps if they are stuck. I will check on them tomorrow to make sure they got out.

Happy gardening and stay safe out there.

Deadly Beauty: Toxic Plants

JM Perez By JM Perez2 min read4.8K views

Contrary to yesterday, today is a beautiful day (still a little windy, but manageable). I’ve been out watering some plants in the backyard when I stopped and took a good look at my Oleanders. What a terrific, yet toxic plant! The plants bloom beautifully in the Summer and they are appealing to the eyes. These deadly beauties were here long before we bought our home and we’ve talked about getting rid of them and/or replacing them. We are all very conscious of their presence and our kids will tell you that ‘Oleanders are deadly and they must not go close to them.’ Still, we always keep an eye on them whenever we are outdoors. Then I thought about my Daffodils.

What about Pheasant’s Eye, Lily of the Valley, Jimson Weed, Poison Ivy, Rhododendron, Jerusalem Cherry, Hydrangea, Mistletoe, Lantana, Mountain Laurel, Dumbcane, Wisteria, Chrysanthemum, Delphiniums, Belladonna, Foxglove, Ranunculus, and Spathiphyllum? These plants are poisonous. Some cause  delirium and hallucinations. Most of us gardeners love them for their beauty, bright colors and fragrance. We care for them without knowing exactly what we are dealing with. Still, we love them. Below is a list of toxic, deadly plants (just to name a few).

Toxic Plants.

Aside from their poison and toxicity, some plants are dangerous. Take Poinsettia for instance. Though non-toxic, its latex can cause an allergic reaction to some individuals when coming in direct contact with the plant. What about Roses? Their thorns could cause serious injuries to anyone who come in contact with them. Some Cacti and Succulents are dangerous, even poisonous, click here for more information. What about those beautiful house plants/air purifying plants? Some are dangerous to kids and pets.

Some plants can cause discomfort, others can kill. The good news is that we can prevent it by being informed. Once you know what you are dealing with, you will be ready, aware and prepared.
