Raspberry spur blight is caused by the fungus Didymella applanata. [2] This plant pathogen is more problematic on red raspberries (Rubus idaeus) than on black or purple raspberries. The fungus infects the leaves first and then spreads to the cane. It causes necrotic spots on the cane near the base of the petiole attachment. [3]
Lomatium canbyi is a species of flowering plant in the carrot family known by the common name Canby's biscuitroot (lúukš in the Sahaptin language and qeqíit in the Nez Perce language). It is native to the Pacific Northwest of the United States and northeast California, where it grows east of the Cascade ridge in sagebrush -covered plateau ...
Tiedemannia canbyi (syn. Oxypolis canbyi) is a rare species of flowering plant in the carrot family known as Canby's dropwort and Canby's cowbane. [2] [3] [4] It is native to the southeastern United States, where it occurs on the Atlantic coastal plain from North Carolina to Georgia, as well as the Chesapeake Bay area.
It is a rare plant in landscapes, but is sold by some large or specialty or native plant nurseries, usually in small pots, as a groundcover. Canby's mountain-lover is listed as a candidate species for federal listing by the United States Fish and Wildlife Service. In 2021, it was listed as 'state threatened' in Kentucky and Maryland.

One study shows that growing chili peppers near tomatoes in greenhouses increases tomato whitefly on the tomatoes. [57] Cucumbers and squash can be used as living mulch, or green mulch, around tomato plants. The large leaves of these vining plants can help with soil moisture retention. [79] Turnips and rutabagas: Brassica rapa and Brassica ...
Plants with more than one significant human use may be listed in multiple categories. Plants are considered domesticated when their life cycle , behavior , or appearance has been significantly altered as a result of being under artificial selection by humans for multiple generations (see the main article on domestication for more information).
Rubus strigosus, as treated here, is widely distributed in North America, particularly the more boreal regions. Some authors also treat various raspberries in eastern Asia, east from the Altai Mountain Range in Mongolia to Manchuria and Japan in this taxon (where it is suggested to have originated along with a great deal of the North American flora), [7] but others include all Asian ...
Rubus leucodermis is a deciduous shrub growing to 0.5–2.5 metres (1 + 1 ⁄ 2 –8 feet), with prickly shoots. [5] While the crown is perennial, the canes are biennial, growing vegetatively one year, flowering and fruiting the second, and then dying.
