Glowing Embers

The popularity of these big, bold plants has grown within the last few years since the new varieties are more hardy and mildew resistant. Hydrangeas should be sited in moist, rich garden soil in partial sun to fairly deep shade. Hydrangeas can be categorized into 4 different types: Mophead, lacecap, Oakleaf and panicle.

Glowing Embers - This gorgeous ornamental shrub with large, lush crimson flowers is truly and eye catcher. It has a compact habit with coarse, deep green glossy foliage with a pretty red tinge. It is a very easy plant to grow as it is disease and pest-resistant. The flowers start out with a white eye and then fully color to solid crimson red blooms. Blossomes are large, 10-12" across and dry well for winter enjoyment. The bloom season is from early summer through late fall.

Endless Summer Hydrangea

Endless Summer has a height of 3 - 5' and is the first macrophylla type to bloom on both old and new wood for large, colorful flower mops all season long. It is remarkably hardy and more mildew resistant than other varieties. The bloom color is blue but will turn pink in alkaline soils and sometimes both blue and pink blooms can be seen on the same plant.
