Wooly Pipevine Seed Germination
We get about a 50% germination rate from our Wooly Dutchman’s Pipevine seeds with no pre-treatment at all. We just plant them about 1/4 inch deep at room temperature (70-80F), keep moist, and they germinate in about 2-3 weeks. Some references suggest soaking in water for 24 hours and/or 3 months of cold-stratification. Perhaps this would improve germination but we haven’t tried it so cannot speak from experience. If you are not going to plant the seeds right away please store them (dry – just the way they are packed) in your refrigerator until you are ready to plant them. These should do fine for fall planting and winter-sowing. We always like to hear your techniques and results so please contact us if you would like to share your experiences!
Aristolochia tomentosa and Pipevine Swallowtail Butterflies
The Pipevine Swallowtail butterflies will lay their eggs on its leaves and the emerging caterpillars will feed on its foliage. They can defoliate an entire plant! But, no worries, the vine will regrow its leaves! There are many different varieties of Aristolochia and some of them (especially the tropical ones) could be poisonous. The “mother” butterfly will not know the difference, and she might lay her eggs on the harmful kind. This is why it is very important to make sure you grow the right species of Aristolochia.
