  • Posted by OldGardener (So Cal - Zone 10b) on Apr 24, 2013 12:03 PM concerning plant:
    A dwarf variety with curly stems and hooked thorns. Germinates in 3-8 weeks but the seeds should remain moist prior to planting for best germination. Will come true 95% of the time from seed. 'Flying Dragon' is often used as the rootstock on grafted citrus due to its dwarfing abilities, disease resistance and cold-hardiness.
