In urma cu zece ani au fost descoperite cele 70 de tulpine care alcatuiesc de fapt stejarul ce masoara nu mai mult de un metru inaltime
Initial, cercetatorii au crezut ca au de-a face cu un grup izolat de copaci, dar au observat ca acestia nu produceau ghinde fertile, astfel ca nu se puteau reproduce. Ceea ce inseamna ca arborii erau de fapt niste clone ale aceluiaai stejar. Analiza genetica a confirmat suspiciunea oamenilor de stiinta care au descoperit ca cele 70 de tulpine sunt identice din punct de vedere genetic.
