One problem with all the C.banksii hybrids has been sudden death of large trunks. I had two 6' trunks die on me in three years.

I would not recommend fertilizers either..they never need it and it MAY burn them if used.

"Cordyline Electric Flash ['Sprilecflash'] PPAF - Another of the interestingly colored Cordyline banksii c...Read Moreultivars coming out of Australia that with Electric Pink and Electric Star provides new bold colored plants with a clumping habit for California gardens. This one has narrow leaves that have a chocolate colored central stripe and cream colored margins - very attractive and unusual! As with the other "Electric" series it is a cultivar of Cordyline banksii, the Forest Cabbage Tree, or Ti Ngahere as it in known in the Maori language. This species is more clump forming like a Phormium and this parentage makes this plant a smaller more clumping species rather than having the tree-like stature of the Cordyline australis cultivars, which easily reach 25 ft. tall. Though listed as only growing to 4 feet, we suspect it will be like the others in the series and approach about twice this with new shoots rising from the base and along the stems. Plant in a well-drained soil. While fairly drought tolerant in coastal gardens, it will certainly be more lush with regular irrigation and should prove hardy to around 15° F, growing well in USDA zones 9-10. This Cordyline banksii hybrid comes from Sprint Horticulture of Wamberal, New South Wales, Australia and was accepted for Plant Breeder's Rights protection in June 2013 and received US Plant Patent 26,267 in December 2015.
