Nothing. You will have a fuller plant that may or may not ever bloom for you. You must correct your cultural treatment of the nobile otherwise it will continue to send out keikis and not new canes. If it were my plant I'd remove all the keikis except those coming from the base of the canes and tailor my cultural practices to what the plant needs: sunny, hot, wet and fertile spring and summers and cold, dry, fertilizer-free fall and winters, and back off high nitrogen.
