Isihlahla seSiliva (Isiliva Leucadendron) isihlahla esingavamile futhi esisengozini yokushabalala esitholakala ezintabeni zase-Cape Peninsula eNingizimu Afrika., kuhlanganisa iTable Mountain. Isihlahla sithola igama laso embaleni ohlukile wesiliva-mpunga wamaqabunga aso, ezinde nezincane ezinomkhawulo ocijile.
Umuthi weSiliva uyilungu lomndeni wakwaProtea futhi uyingxenye ebalulekile yezitshalo ze-fynbos ezitholakala esifundeni saseNtshonalanga Kapa.. Kuyisihlahla esikhula kancane esingafinyelela phezulu 10 amamitha (33 izinyawo) ngobude kodwa itholakala kakhulu ezindaweni eziphakeme nxazonke 2 kwa- 4 amamitha (6 kwa- 13 izinyawo).
Isihlahla sikhiqiza izimbali ezincane eziphuzi noma ezimhlophe ezizungezwe ezinkulu, ubukhazikhazi, ama-bracts anombala wesiliva. Izimbali zithuthwa impova yizinambuzane, lembewu ihlakazwa ngumoya.
Isihlahla seSiliva sithathwa njengohlobo lwenkomba ye-fynbos ecosystem enempilo futhi engaguquki, njengoba izwela izinguquko endaweni yayo futhi iwumthombo wokudla obalulekile wezinhlobonhlobo zezinyoni nezinambuzane. Lesi sihlahla sibalulekile futhi ngokwesiko kubantu bendabuko yamaKhoisan, abasebenzise amaqabunga awo ukwenza imithi nezingodo zawo ekwenzeni amathuluzi.
Ngeshwa, iSilver tree sibalwa njengezinhlobo zezitshalo ezisengozini, nezinkulungwane ezimbalwa kuphela zabantu abasele endle ngenxa yokulahlekelwa indawo yokuhlala nezinye izinsongo. Njengamanje imizamo yokulondoloza iyaqhubeka ukuze kuvikelwe futhi kubuyiselwe lezi zilwane nendawo yazo, okuhlanganisa nezinyathelo zokuvimbela imililo, lawula izinhlobo zezitshalo ezihlaselayo, kanye nokukhuthaza izindlela ezisimeme zokusetshenziswa komhlaba.
