Agave 'Royal Flush'
Agave 'Royal Flush' is a new variegated cultivar of Agave 'shira ito no Ohi'. This is a wider margin plant and just as easy to grow. This is another species that grows as fast as the pot you plant it in. Small pot means small plant, big pot means large plant! These should be able to take down to around 12F or more in winter. Agave 'shira ito no Ohi' has taken 9F for me in the past with no damage but these are more variegated so it will be less cold hardy I would think?
