A large, evergreen tree, Cupressus × leylandii reaches a size between 20 and 25 m high, with its leaves giving it a compact, thick and regular habit. It grows very fast with yearly increases of 1 m. The leaves, about 1 mm long and close to the twig, are presented in flaky, slightly aromatic branches. They are dark green, somewhat paler on the ...
The leaves are scale-like, 2–5 mm long, and produced on rounded (not flattened) shoots; seedlings up to a year old have needle-like leaves 4–8 mm long. The seed cones are globose to oblong, 20–40 mm long, with 6–14 scales, green at first, maturing brown about 20–24 months after pollination.
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 ...
Cypress are evergreen trees or large shrubs, growing to 5–40 m (16–131 ft) tall, exceptionally up to 102 m tall (the second-tallest tree species on earth, after Sequoia sempervirens) in Cupressus austrotibetica. [5] The leaves are scale-like, 2–6 mm long, arranged in opposite decussate pairs, and persist for three to five years. On young ...
A geophyte (earth+plant) is a plant with an underground storage organ including true bulbs, corms, tubers, tuberous roots, enlarged hypocotyls, and rhizomes. Most plants with underground stems are geophytes but not all plants that are geophytes have underground stems. Geophytes are often physiologically active even when they lack leaves.
A flowering Fenestraria rhopalophylla, so named due to the translucent leaf window on the tips of its modified leaf.. Leaf window, also known as epidermal window, [1] and fenestration, [2] [3] is a specialized leaf structure consisting of a translucent area through which light can enter the interior surfaces of the leaf where photosynthesis can occur.
The plant's flowers are yellow and grow up to an inch in diameter, with five petals attached at the base. Flowers grow on stalks and can either be found in clusters or individually where the stalk meets the leaf stem. [4] Pod-like capsules produced by the plant consist of 12-15 wood segments that form cup-like rings.
