Earlier this week I wrote about plants at the National Botanic Gardens of Ireland which would be pollinated by beetles, geckos and lemurs in their natural habitats. There were too many fun facts to fit into one post! Here are a few more plants which deserved a special mention…
Many of the orchids in the palm house were in bloom when my Dad and I visited at the end of February. Each one is perfectly evolved for pollinator-specific relationships. They have landing platforms for bees, pungent odours to attract flies, or they imitate insects like our own native bee orchid.
This is where the National Botanic Gardens boasts another pollination wonder from Madagascar – Angraecum sesquipedale. In 1862, Darwin theorised that this long-nectaried orchid could only be pollinated by a moth with an equally long proboscis, which would have co-evolved with the plant. In 1907, more than 20 years after Darwin passed away, that very moth (Xanthopan morganii praedicta) was found in Madagascar.
Finally, we were treated to some real pollination in action. We spotted a queen Bombus terrestris/lucorum fuelling up on the flowers of a Pieris sp.
Queen bees emerge early to begin searching for nest sites in places such as the lovely untidy, tussocky bases of hedgerows. Early flowering plants are essential to their survival, so let those dandelions and other “weeds” bloom! Don’t mow, let it grow!
