With a name like Hosta 'Titanic', you can imagine how big this hosta will become. Old clumps may surpass the 9' wide record of its parent Hosta 'Sum and Substance'. This sport of Hosta 'Sum and Substance' boasts a very wide golden border surrounding the glossy, chartreuse-green leaf centers, even when young. It is far more dramatic than the first introduced edged forms of Hosta 'Sum and Substance'. This should only be planted where space is not a problem. The clumps are topped with large, light lavender flowers in midsummer.
