Plant of the Day
Wednesday 27 March 2024
These clumps of the newly emerging foliage of Euphorbia × pasteurii 'John Phillips' (spurge) were creating a great contrast with the finely textured grasses. From late spring into summer honey-scented, yellow-green flowers will be produced.

Euphorbia myrsinites (donkey tail, myrtle spurge, blue spurge)
Handle with Care
I've always called this plant a donkey tail but it's probably better known as myrtle spurge. Euphorbia is a big genus with over 2000 species but I'm afraid that donkey tail is 'the bad boy of the family'. It's native to Italy, the Balkans and Turkey but it's considered a noxious weed in Utah, Oregon and Colorado. According to the Salt Lake County Weed Control Program, "Small infestations can be controlled through multiple years of digging up at least 4" of the root. Myrtle spurge is best controlled in the spring when the soil is moist and prior to seed production. Make sure to dispose of all the plant parts in the garbage instead of composting." Goggles and rubber gloves are strongly advised.
Why all this heavy security? All Euphorbias produce a poisonous sap which burns the skin and can cause blindness if it gets in your eyes. If you eat the leaves, you get vomiting and severe diarrhea. This milky sap is a very good defense against any type of herbivore. Donkey tail in particular is extremely toxic to: humans, cattle, sheep, pets etc. etc. Rabbits and deer won't go near it. It has no known North American insect pests. Not surprisingly, it should never be planted next to a playground.
On the other hand, donkey tail is a common ornamental plant and widely available in local plant shops. Euphorbia myrsinites has also been awarded the Royal Horticultural Society's, Award of Garden Merit. It has attractive blue foliage, a very long blooming period and thrives in poor soil. But pleased be advised: Handle with Care.

Euphorbia grandicornis
Euphorbia is a huge and extremely variable genus, but Africa has many spiny species that remind people of cactus plants, although they are not related. This one is Euphorbia grandicornis (meaning "big horn", in reference to its formidable spines), a shrubby species from the northeastern part of South Africa, as well as neighboring Mozambique and Eswatini. The dramatic "wings", formed by the widening and narrowing of its stems, are reminiscent of Euphorbia cooperi, but the latter becomes a large tree. Like most Euphorbia species, these two are quite poisonous, so care must be taken not to let the sap come into contact with one's eyes or other sensitive areas. The tiny yellow cyathia (the little cups containing the flowers) seem very small for such an impressive plant.

Euphorbia characias (var. wulfenii) (Mediterranean spurge)
Green flowers
Flowering plants evolved about 140 million years ago but for the first forty million, they weren’t particularly colorful. Their basic contract with insects was the same, you help us with seed production and we’ll give you food (pollen and nectar) in return. But then the bees evolved and, all of sudden, flowering plants became a lot more beautiful. This is because bees have much better color vision than most insects. Bees are sometimes described as wasps that became strictly vegetarian.
Maybe, the Mediterranean spurge didn’t get the memo - it has green flowers! All true petals developed from conventional leaves anyway but this spurge seems to have got stuck, half way through the process. What appear to be green, cuplike petals are just highly specialized leaves (bracts) but bees are still attracted to it’s flowers. In addition to almost full-color vision, bees are very good with edges, and they can see this flower’s shape just fine.

Euphorbia susannae
The genus Euphorbia is a huge one, containing everything from common garden weeds to cactus-like stem succulents. If it weren't for their unique flowers, nobody would suspect they were all related. Their flowers are tiny and lack petals, and they pop up out of the middle of a cup-like structure called a cyathium. Around the edge of the cyathium are five glands (olive green in color in the plant pictured). While some species of Euphorbia have both male and female flowers together in one cyathium, others have separate male and female plants, as is the case with Euphorbia susannae. The plant shown is a female, with its little fork-tipped styles protruding from the center of each cyathium. Native to South Africa's Little Karoo region, famed for its many succulents.
