As ever late for @wildflowerhour.bsky.social #wildflowerhour . Favourite plant finds this year were the tiny lesser twayblade in Yorkshire, thyme broomrape in the Burren and creeping lady's-tresses in Norfolk. #favouritefinds #favouriteplants #ukorchids #broomrape

Figure 6. Phelipanche ramosa seed germination with MG 4-Quat (Mg4) sanitizer at 1% (v/v) concentration in the presence of 100 mg ml-1 soil powder for 1-, 5-, and 10-min exposure duration with or without surfactant. Su, Lansurf AEP63 surfactant. Data are means ± SE (n = 6), and treatments with the same letters did not differ according to two-way ANOVA.

🌱 From Weed Science: Quaternary ammonium compound (QAC) sanitizers can reduce #broomrape seed spread, but debris limits efficacy. Pre-cleaning equipment is key. (Pershang Hosseini, Cassandra L. Swett, Bradley D. Hanson)

To the left and in the background: an ivy-covered wall. Centre front: A large inflorescence of “meat coloured” Ivy-Broomrape. Inbetween: Three smaller inflorescences of broomrape. Also seen: green Geranium leaves, withered ivy leaves. Weather: somewhat overcast, with only indirect sunlight.

Inflorescences of Orobanche hederae (🇬🇧 Ivy-Broomrape | 🇩🇰 Vedbend-Gyvelkvæler) at the foot of an ivy-covered wall. Shot today.

Knapweed Broomrape (Orobanche elatior) and its host Greater Knapweed (Centaurea scabiosa).

The amazing Knapweed Broomrape (Orobanche elatior) and its beautiful, and only, host - Greater Knapweed (Centaurea scabiosa). Look how big some of them are! #Wildflowers #broomrape

Broomrape is a new one for me; would its host be clover, given its proximity to that flower - seen last week at Wandlebury, Cambridgeshire

(clockwise from top left): Common Spotted Orchid (rubbish name), Lesser Butterfly Orchid, Common Twayblade, Knapweed Broomrape (not an orchid but a parasite of Knapweed), Musk Orchid, Fly Orchid, Chalk Fragrant Orchid, Pyramidal Orchid.

I drove from Dorset to Surrey today and made two stops, one in the New Forest, one near Selbourne. I didn’t have a lot of time but I still managed to see all these beauties ! See alt text for details. #orchid #broomrape

The Common Broomrape in Clayton Meadow. A non-photosynthetic plant that has no leaves and is parasitic on a host plant.

I pulled a stray #Hedera helix (🇬🇧 Ivy 🇩🇰 Vedbend) and this is what I found. Could it be the subterranean part of an #Orobanche hederae (🇬🇧 Ivy Broomrape 🇩🇰 Vedbend-Gyvelkvæler)?

Old drawings of broomrape species: 1. Orobanche minor (common broomrape). A tall yellow stalk with pale pink blossoms demonstrated parasitizing a clover. Native to parts of Europe, Asia, and Africa but introduced through anthropogenic means to the United States and other parts of the world where it is largely considered to be a noxious weed and an agricultural pest on legumes. 1a. seed vessel, opened 1b. section of seed vessel 2. Lathrea squomaria (common toothwort). A cluster of tall yellow stalks with purple and yellow flowers that look similar to violets. Native to England. 2a. seed vessel 2b. seed vessel, opened 3. Aeginetia acaulis (no common name). A pale yellow stalk with peach blossoms. Native to parts of Asia. 3a. flower opened 3b. stamens 3c. pistil 3d. ovary

Inflorescence of branched broomrape parasitizing Medicago lupulina in northeastern Texas. The relationship between these ruderal broomrape populations and those that parasitize cultivated tomatoes in California and Chile has been controversial, with some suggesting that they are a separate species. In “Multiple genotypes of Phelipanche ramosa indicate repeated introductions to the Americas”, Schneider determined that these three populations, as well as a fourth centered in Virginia, form distinct genetic groups that are probably the result of both separate introductions from Eurasia and gene flow between P. ramosa and its relative P. nana.
