Gentle traps: Aristolochia
Aristolochia (Dutchman’s pipe) hardy species are not often seen cultivated in the gardens. It is a pity since they are quite interesting.
I wrote before that serepindity made it to grow successfully from seeds two such species: Aristolochia iberica and Aristolochia steupii, both hailing from the Caucasus and surrounding regions.
They are both deciduous, trailing vines of deciduous forests, short in stature though, with ‘pipe-like’ typical flowers (hence the generic name Dutchman’s pipe) along upright leafy stems produced in late spring. The flowers are not large, but they are so unusual they make you want looking at them again, and again…The flowers have hairs which will guide and shortly trap insects, but this doesn’t mean they are carnivorous. The pollinators find their way out after performing the ‘required’ task.
Aristolochia iberica: mature capsule showing the seeds. The seeds germinate best when sown fresh or moist packed
The fruits are egg-shaped, hard capsules which will split and release the seeds on short notice. The seeds bear resemblance to those of other species from the family, like Asarum and Saruma. Like ways, their seeds also require a slightly warm/cold cycle for proper germination; if they get very dry the germination rate is greatly reduced.
Another hardy Dutchman’s pipe is our native Aristolochia durior, which grows tall and needs a support or can ‘hang on’ to a nearby tree. I still have to add this one to the garden.
Meanwhile, even if the spring has been cold and capricious, Aristolochia iberica has produced a few capsules & good seeds.
Those who want to grow something cool, that almost no one else has, give it a try. Show it off to your garden friends as a ‘rarity’ :)
The seeds will become available on Friday, together with few other moist packed seeds.
They are species for the woodland garden, part sun/shade works best (morning sun), in locations with good, rich substrate where you would water during dry spells. They can be good companions for: Saruma henryi, Asarum, Hepatica acutiloba, evergreen Epimediums, Podophyllum, Helleborus, to mention the few that are in my garden bed; also Arisaema ssp. Uvularia, Trilliums, Hydrastis and so on….
Hold your breath because Hydrastis canadensis seeds will also be available soon!
*Although Aristolochia species have been employed for medicinal purpose to treat various ailments, due to the mutagenic properties of the aristolochic acid (found in all plants of this family), today it is advised not to use any preparations based on Aristolochia species.
