What is special about the dead horse arum?
One of a rare group of thermogenic plants, the dead horse arum can raise its temperature by thermogenesis. This helps to lure flies into the plant to contact its pollen. The plant still is being studied for the way it is able to produce its own heat without being necessarily dependent of ambient temperature.
What pollinates the dead horse arum?
Many arums are pollinated by the kinds of flies which are attracted to carrion. If a flower smells like rotting meat (or something worse), it will attract these potential pollinators. Another surprising ability of this plant is that it generates heat as the flowers mature and emit their scent.
How does the the dead horse arum attract blowflies to pollinate them?
The long, finger thing that looks like a hairy tail is the spadix, and it produces a scent that smells akin to a rotting corpse. This alone will attract blowflies from all around.
Do arum lilies produce seeds?
Planting in the Ground. Allow Arum lily fruits containing the seeds to turn brown and dry before picking them. The fruits will develop in the fall after the plant has bloomed and the flowers are spent.
How do you propagate arum lilies?
The simplest and quickest solution for growing arum lily is to multiply it by division of rhizomes or plant bulbs. You can also grow it from seeds: Sow seeds on the surface of a hot and humid soil in spring or summer. Keep them in a bright location. Germination takes place between 1 and 3 months.
Can arum lily be grown from seed?
Arum Lily Care and How to Grow it You can also grow it from seeds: Sow seeds on the surface of a hot and humid soil in spring or summer. Keep them in a bright location. Germination takes place between 1 and 3 months.
What do I do with lily seed pods?
Snip off the seed capsules and break them open over a bowl or other container. The seeds lose viability quickly and are more likely to germinate if sown immediately after gathering. They can be stored until spring if kept in the refrigerator, although stored seeds have a much lower germination rate than fresh.
How do you plant Arum seeds?
Fill a small container with warm water and place the Arum lily seeds into it. Allow the seeds to soak overnight before planting in soil. Fill a planting container with a well-draining potting mix that is rich in organic material. Be sure the container has holes in the bottom for drainage.
Should I cut off lily seed pods?
Most flowering plants, including daylilies, expend a tremendous amount of energy on seed production. Seed production in turn takes away from root and shoot development and future flowering potential. From a plant health perspective, seed pods should be removed so that daylilies will produce more flowers next season.
Can I grow arum lilies from seed?
To start your calla lily seeds, spread them on a damp paper towel and lightly cover. Keep the paper towel in a cool place, away from direct sunlight, and check them every few days for growth. Once they start to grow, you can plant them in soil (and discard the ones that haven’t sprouted).
How do you propagate Arum?
What is a dead horse arum?
Growing from a tuberous root, the dead horse arum ( Helicodiceros muscivorus) unfurls its leaves in early spring and produces a single, large bloom shortly after. The flower is a spathe-and-spadix type, typical of the arum family.
How does the dead horse arum get pollinated?
The dead horse arum has a two-day process for pollination. The individual flower is able to receive pollen for one day only, and usually that day its male parts are not mature. Although the male part is able to produce pollen the next day, the female part shrivels up and cannot receive it.
Why do dead horse arum flowers attract flies?
The flowers of H. muscivorus smell like rotting meat, attracting carrion-seeking blow flies which act as pollinators. One of a rare group of thermogenic plants, the dead horse arum can raise its temperature by thermogenesis. This helps to lure flies into the plant to contact its pollen.
Who is minding our dead horse arum?
This last shot is of Wave Hill gardener Susannah Strazzera, who has been minding our dead horse arum since we acquired it ten years ago. It’s been a long ten years waiting for it to bloom, and her excitement has been contagious: staff wander over to the Alpine House mid-morning to check out this horrible wonder.
