What is the difference between the poison bulb (Crinum asiaticum) and the spider lily (Hymenocallis littoralis)? The latest detailed comparison
The poison bulb (Crinum asiaticum) and the spider lily (Hymenocallis littoralis) are two very similar plants. If you are not very familiar with flowers, or have only seen one of them, it is very easy to confuse the two. So are the spider lily and the poison bulb really that hard to tell apart? Below, Qinnong Web will introduce the differences between the poison bulb and the spider lily.
⟦NL>I. Brief introduction to the spider lily and the poison bulb
The spider lily is a flower-type ornamental plant. It can be grown in pots indoors and can also be used to decorate courtyards. The spider lily is native to tropical America; after being introduced to southern China, it was planted for ornamental viewing. This plant likes a warm, humid, and fertile growing environment, is not cold-tolerant, and likes places with plenty of light. The poison bulb is also an ornamental flower, but it is not, as people think, a member of the orchid family. It is a perennial herbaceous plant in the Amaryllidaceae under the order Asparagales. It likes warm, humid, sunny sandy soil environments. The poison bulb is widely distributed in southern China and is often seen on seaside or riverside sandy areas.
II. Differences between the poison bulb and the spider lily
1. Different leaves
The spider lily has multiple leaves, concentrated at the base and growing clasping the stem. The leaves are sword-shaped, about 45-75 cm long and 2.5-6 cm wide. They grow oppositely, are dark green in color, and have leaf veins.
The poison bulb has more leaves, 20-30 of them, 0.9-1.2 m long and 7-12 cm wide. The leaf margins are wavy, and they look limp. The light green leaves are broad, thick, and fleshy, growing on the upper half of the plant.
The leaves of the spider lily are stiffer than those of the poison bulb, and the midvein depression is more obvious. In terms of number, the poison bulb has more leaves, and the leaves are also longer and broader. The leaves of the spider lily are opposite, while the leaves of the poison bulb look as if they are growing in a spiral.
2. Different flowers
The difference in flowers is more obvious at a glance than the leaves, and it is also the simplest way for us to distinguish the two.
The green of the spider lily's style is deeper, and its surface looks as if covered with a layer of frost, and it is not as green and smooth as the style of the poison bulb.
The petals of the poison bulb are purplish red in the middle and pink on both sides. When fully open, they spread out in all directions and may even curve backward. The petals of the spider lily are slender and very widely separated, and when fully open, the front ends of the petals turn slightly downward. The biggest difference between the spider lily and the poison bulb is that the spider lily's flowers have an umbel-like corona, making the difference obvious.
Besides the difference in flower shape, the number of flowers is also different. Each inflorescence of the poison bulb usually has 10-24 flowers, while the inflorescence of the spider lily usually has 3-8 flowers born at the top of the scape, within 10 flowers. With careful observation, the two are not difficult to distinguish.
