Hydrangea - Penny MacScientific Name: Hydrangea macrophylla
Best Planted In Zone: 5-9
‘Penny Mac’ is a great Hydrangea for the far north, where late frosts kill off the buds of other varieties. 'Penny Mac' reblooms heavily in fall on new wood, so even if you miss the first flush, great color awaits you in the shady garden. You'll love these big 7-inch clusters of deep blue, offset by lush, simple foliage of dark green. They look splendid on the shrub, and are gorgeous in fresh arrangements. You can even let them dry to a lovely powder-blue and use them as Everlastings all winter. At maturity, this hydrangea shrub reaches 3-4 feet tall and 3-4 feet wide, making it ideal as a foundation planting, specimen, or accent. ‘Penny Mac’ thrives in partial to full shade and moist, well-drained soil. Very tolerant of heat and humidity, it appreciates regular watering during dry spells. Space the plants about 4 feet apart and water well during growth. USDA ZONES: Zone 5, Zone 6, Zone 7, Zone 8, Zone 9.

Choose a location where your hydrangea can reach its full size without pruning. For normal sized hydrangeas, expect the plant to reach about 4 ft. X 4 ft. Plant in well-drained soil! If soil is heavy, add roughage such as pine bark mulch. Do not over water, esp. in clay soil. This can lead to root rot. Do not plant too deeply. Plant at the same depth the hydrangea was planted in the pot. Hydrangeas can be planted any time of the year, though if possible you should plant in early summer or fall. If you plant too early in the spring or too late in the fall you run the risk of losing your freshly planted hydrangea. If you do plant out of season, just make sure to pay attention to your plant and be on hand to provide extra care when needed. Transplant a hydrangea when it has become dormant and lost all of its leaves (late fall or winter). Your hydrangea will need supplemental watering the first two years after planting, but don’t go overboard, as overwatering can quickly lead to rain rot. It is best to fertilize your hydrangeas once or twice in the summer but do not fertilize after August, as fall is when the plants begin to prepare for dormancy. If you fertilize too late in the summer it could encourage new growth that will make your plant too sensitive for winter.
This hydrangea blooms on both old and new wood. Pruning is generally not needed, but it may be trimmed lightly after the early bloom. Bloom color can be shifted to blue with the addition of aluminum sulfate to the soil. Best in moist, well-drained soils. Supplemental moisture may be needed in very hot or dry conditions. Fertilize in spring with a controlled release fertilizer.
