In Narberhaus Square, our exhibition of pumpkins is already on display once again. A showcase of varieties that surprises with the diversity of shapes, colors and sizes, and that reminds us how much this fruit has accompanied humanity throughout history.
This year we present 17 varieties from different genera —Cucurbita and Lagenaria—. The seeds, initially obtained from the cooperative Les Refardes, are now part of our own conservation cycle. The pumpkins sown in March come from the previous year’s harvest at Marimurtra. Among the most unique specimens we find the “Sicilian snake” (Lagenaria siceraria longuissima), the giant pumpkins of Cucurbita maxima, or the delicate varieties of Cucurbita moschata, such as the “Violín” or the “long of Gironella.”
Beyond the shape: the value of conserving varieties
Pumpkins belong to the family Cucurbitaceae, with more than 120 genera and around 900 species. Cultivated for about 15,000 years, they have been used for food, medicine and even as everyday utensils, especially in the case of bottle gourds (Lagenaria siceraria).
Preserving local varieties is key to keeping this diversity alive. In times of globalization and monoculture, these collections remind us of the value of an agricultural heritage that must be preserved.
A curiosity this year: hybridizations
This year we have detected that some pumpkins from Marimurtra have undergone hybridizations unintentionally. We do not know exactly which species have crossed, but specimens have appeared with traits that combine characteristics of different varieties and that, therefore, do not correspond to the original species.
Why does it happen?
Pumpkin plants belong to the family Cucurbitaceae, with species that are very close and often compatible with each other. This means that when they receive pollen from another variety —carried by the wind, insects or other animals—, hybrids can be generated naturally. The proximity between plants and the coincidence of flowering make this exchange even easier.
This hybridization phenomenon is not negative in itself, as it can give rise to new forms and possibilities. However, when the goal is to conserve specific local varieties, it must be monitored: if not properly controlled, some characteristic traits may be diluted or eventually disappear.
Come and see them!
The exhibition can be visited throughout the autumn in Narberhaus Square, in the second garden of Marimurtra. The goal is to showcase agricultural biodiversity and highlight the importance of conserving traditional varieties.
