Named for Penny McHenry of the American Hydrangea Society, this selection is touted to be the H. macrophylla that blooms on new wood!... an exciting break-through. PSh/M (not dry) acid: blue, alkaline: pink.

Penny Mac Hydrangea is a prolific rebloomer, blooming on new wood. Therefore, it blooms even in areas where buds of other hydrangea get killed by late frosts. Penny Mac Hydrangea is seaside/salt tolerant. As with most mopheads, the blooms are more pink in alkaline soil and more blue in acid soil. Penny Mac Hydrangea is named after Mrs. Penny McHenry, founder of the American Hydrangea Society.

The glorious history of Penny Mac hydrangea can be read about other places on Google, but we'll encapsulate it by honoring the namesake, Penny McHenry, for her passion for hydrangeas and gardening. She founded the American Hydrangea Society right here in Georgia. Penny Mac is a remontant mophead Hydrangea macrophylla from her garden. This cultivar is a beautiful treasure, a conversation piece, and a garden stalwart. It's a classic "Cape Cod blue" mophead that will stand up to any other remontant mophead, any day and every year. As with all macs (except white ones), the flower color depends on pH and aluminum availability in the soil (low/acid pH = blue while high/alkaline/basic pH = pink).

A great repeat bloomer with large flower heads. Blue tones in acidic soil and pinks in alkaline soil. Growth Rate fast

This is an exciting breakthrough in Hydrangeas. Penny Mac blooms on old and new wood, so it is a reliable bloomer even in colder areas where buds are frequently killed by late frosts. Penny Mac has huge flowers of pink over white in alkaline soils, or turns a vivid blue in acid soils. Named after the founder of the American Hydrangea Society, Mrs. Penny McHenry. Grows to 4-5' tall and wide after 10 years.

Another great variety that blooms on new wood. Named for Penny McHenry, the founder of the American Hydrangea Society, this vigorous hydrangea is great to zone 5 based on recent surveys. It will even bloom twice if pruned after first blooms. Penny Mac is great for those areas where early fall or late spring frost kills other hydrangea buds. The blooms are HUGE and are pH sensitive. The blooms will age red for added fall color. We miss you, Penny!

What is important about this pink or blue dense mophead is that it flowers on new wood.

By: Whitman Farms

A very prolific bloomer, this flowers onnew wood and will keep producing flowers throughout the summer. The mophead flowers will be pink if in alkaline soil or blue if in acid. Like most mops, these dry quite handsomely so you can enjoy these during the winter as memories of summer.
