Striga, commonly known as witchweed, [1] is a genus of parasitic plants that occur naturally in parts of Africa, Asia, and Australia. It is currently classified in the family Orobanchaceae, [2] although older classifications place it in the Scrophulariaceae. [3]
Dig or pull weeds by hand. You can weed at any time of the year, but the best time to pull weeds is after it has rained, when the soil is moist and loose. Use a pre-emergent and post-emergent product.
As a result, a corm cut in half appears solid inside, but a true bulb cut in half reveals that it is made up of layers. [3] Corms are structurally plant stems, with nodes and internodes with buds and produce adventitious roots. On the top of the corm, one or a few buds grow into shoots that produce normal leaves and flowers.
O. umbellatum is a perennial herbaceous bulbous plant , dying back after flowering, to an underground storage bulb. The following year, it regrows from the often shallow rooted bulbs, which are ovoid with a membranous coat, [ 2 ] 15–25 millimetres ( 1 ⁄ 2 –1 inch) long and 18–32 mm ( 3 ⁄ 4 – 1 + 1 ⁄ 4 in) in diameter.
S. asiatica seedlings are not visible above ground, but white succulent shoots can be found attached to host roots. Mature plants have green foliage above ground, sparsely covered with coarse, short, white, bulbous-based hairs. Mature plants are normally 15–30 centimetres (5.9–11.8 in) tall, but have grown to 60 centimetres (24 in).
In gardening, a "bulb" is a plant's underground or ground-level storage organ that can be dried, stored, and sold in this state, and then planted to grow again. Many bulbs in this sense are produced by geophytes – plants whose growing point is below ground level. However, not all bulbs in the gardening sense are produced by geophytes.
The bulbils on the vines sprout and become new vines, twisting around each other to form a thick mat. If the plant is cut to the ground, the tubers can survive for extended periods and send up new shoots later. [11] The leaf beetle Lilioceris cheni has been studied and employed as an agent of biological pest control for the plant, with releases ...
Allium triquetrum is a bulbous flowering plant in the genus Allium native to the Mediterranean basin. It is known in English as three-cornered leek or three-cornered garlic, in Australia as angled onion, [4] and in New Zealand as onion weed.
