Corylus avellana – Common hazel

View prices and availability
Alunul comun este un arbust puternic care crește până la un copac mic cu mai multe tulpini, cu o coroană rotundă și dens ramificată. Crengile tinere, de culoare maro, sunt ușor păroase, iar scoarța mai veche se desprinde ușor după câțiva ani. Frunzele de culoare verde mat sunt, de asemenea, păroase și, prin urmare, se simt oarecum aspre. Toamna, acestea devin galben-maronii. Catrinii masculi grațioși sunt vizibili înainte de iarnă, dar se deschid pe la sfârșitul lui februarie. Micile flori feminine roșii cresc din mugurii frunzelor și sunt discrete. Fructele se coc în jurul lunii septembrie. Alunițele sunt parțial închise de două frunze de rod. Alunele au un conținut ridicat de grăsimi vegetale și proteine, ceea ce le face o delicatesă sănătoasă. Sistemul radicular este susceptibil la sufocare. Poate fi aplicat pe orice sol, cu condiția ca acesta să fie suficient de aerisit și deshidratat.
