The huge variety of sizes and blooms is what makes hydrangeas so appealing. For plush pink or blue flowers, look for macrophylla varieties, also called lacecap or mophead. Paniculata types are larger with conical flowers, great for mixed borders or hedges. The foliage of Oakleaf hydrangeas have brilliant color in the fall. For perennial vines that reach impressive heights, choose climbing hydrangeas.
