Although hostas are basically grown for those beautiful leaves, there are some hosta varieties that have quite beautiful flowers. Removing these are not necessary for the health of the plant, so whether you choose to cut the flower spikes off or allow them to grow and flower is a matter of personal choice.
Hosta flowers form on long scapes that usually tower above the hosta leaf mound. The bell or funnel-shaped flowers hang down from the scapes.

Reasons to Remove Scapes and Flowers
If you're trying to grow the size of your hosta, cutting off the flower stalks when you see them will divert more energy to the hosta leaves and roots, giving them the added strength to grow larger.
Quality of the Flower Bloom
Because most hostas have been bred for their beautiful leaves, the quality of the bloom is many times an afterthought. Many hosta varieties have flowers of only 2” high, and some flowers are rather bland and unattractive. Some gardeners prefer to cut the stalks as soon as they appear simply for aesthetic purposes.
If you remove the flower stems on a hosta, it will usually not flower again that season.
