I received a hydrangea as a (apparently) a houseplant. Anyway it was in a small container with a decorative outer container to place the whole plant in. How do I care for this through the winter in Indiana? It is already freezing and doubt one would set it out.

tw - I had received a "florist" hydrangea years ago and was able to do a little research on the plant name. Discovered that it wasn't really hardy below zone 6 or 7. I put it in a larger pot and it spends the warmer months - maybe spring through fall - outside in a shady spot. I bring it in over winter or put it in a cold frame where I maintain a temp above freezing. Does need fresh soil every couple of years. Hope that helps.

In Zones 6 or colder, you need to have either (a) hydrangea paniculatas, (b) hydrangea arborescens (smooth hydrangea), (c) hydrangea quercifolia (oakleaf hydrangea) or (d) a rebloomer version of a mophead or lacecap hydrangea. If you have a non-rebloomer version of a mophead/lacecap, you will need to grow it in a pot and keep it inside during winter as shadegardener suggested. If you were to plant a nonrebloomer mophead/lacecap outside say in Zone 5, the flower buds and stems will very often get zapped by winter... And every year, you end with green leaves and no blooms. I would recommend very low growing rebloomers like those from the Lets Dance Series.

Mopheads develop invisible flower buds at the ends of the stems in July-August and these open in the Spring. Keeping the shrubs inside during winter protects the invisible flower buds and the stems from getting zapped by cold temperatures.
