What is a Sulfur Flower or Wild Buckwheat?
Native to western North America, the sulfur flower is a Polygonaceae plant that thrives in a variety of habitats, including the sagebrush steppe and alpine regions. It is a perennial that spreads and forms a mat and is known for its tiny, sulfur-yellow flowers that bloom from late spring into summer.
The plant can reach heights of 12 feet with low-growing basal mounds of leathery, spatula-shaped, gray-green leaves. Both a basal rosette below the main flower stalk and whorls at the tips of short woody stems emerging from the woody plant base have leaves on them.
The sulfur flowers change as they age from sulfur yellow to cream to orange-yellow. They eventually turn brown and look beautiful in dried arrangements. It is a great option for the landscape’s dry areas. Additionally, it is utilized as a ground cover in mounds, banks, slopes, and butterfly and rock gardens.
Keeping Cats Away From Sulfur Flower or Wild Buckwheat
Cats detest uneven terrain. They adore using smooth surfaces for digging and walking. Your plant beddings might be more cat-repellent if they are rough.
To make a surface that is uncomfortable to walk on, try laying chicken wire under mulch or burying it in the top layer of soil (with holes drilled for plants). You can use these items because cats will try their best to avoid areas covered in stones or pebbles.
To create a bristly barrier for cats without destroying the garden’s natural aesthetic, you could also try stuffing gaps around bedding with a collection of pine cones or branches.
