> Alpenglow Mophead Hydrangea - trade gallon
Hydrangea macrophylla ’Alpengluhen’ is a fine, crimson to purple mophead, depending on your growing pH. It is one of the best to resist blueing in acid soil, although in mid-5 pH soil it will tend purple. Very handsome glossy foliage. Our west coast competitors (and friends) say it is one of the best for them. Grows to 5’ x 5’. Part shade. Early to late season. Zones 6 - 9.
> Kardinal Lacecap - trade gallon
Extraordinarily deep red lacecap if you grow Hydrangea macrophylla ’Kardinal’ in sweet soil, otherwise it will tend to purple. Robust shrub to 5 feet with good green foliage. Even so, as one of the Teller series of lacecaps, it needs to be protected from the late frosts of the season because it buds out when spring is still a hint. Zones 6 - 9.
> Lady in Red Lacecap - various sizes
Bred at UGA under the direction of Dr. Dirr, this is a stout shrub to 4 feet or so with a light pink lacecap flower that ages to a darker pink later in the season. The stems and leaves are suffused with red and become even more striking in the fall. Hydrangea macrophylla ’Lady in Red’ is very mildew resistant, a major plus for us in the hot, humid south. Zones 6 -9.
> Lighthouse Mophead - trade gallon
Robert Mallet of the Shamrock Collection in France lists Hydrangea macrophylla ’Leuchtfeuer’ as one of the 3 best reds on acid soil, which is always a hard task. It is known in this country as "Lighthouse" or even "Beacon Light" if it is available at all. Under any name it is a robust grower with deep pigmentation that resists turning blue on acid soil. Quite a splendid plant. To 4 feet, in partial shade, for zones 6 through 9.
> Montgomery Mophead - trade gallon
A mid-sized mophead not generally available in this country although well respected in Europe & New Zealand, Hydrangea macrophylla ’Montgomery’ has ruby-red flowers on alkaline soil or magenta on acidic. Height to about 4 feet, perhaps a bit more. Shared with us by the Mallets from their Shamrock Collection (France) years ago when such was possible. Zones 6-9.
> Oregon Pride Mophead - trade gallon
Deeply toned red or purple mophead on this sport of ’Merritt’s Supreme’. Dark red to purple stems. Height to 3 feet. Rather tender so site well in garden. Zones 6-9. Photos courtesy of the J. C. Raulston Arboretum.
> Rotschwanz Lacecap - trade gallon
One of the best of the "Teller" series of hydrangeas introduced by the Federal Research Institute for Horticulture, Wädenswil, Switzerland. When grown in sweeter soil it has a blood-red sterile sepals surrounding a light pink fertile center. The foliage is dark green and wrinkled. Height to about 4 feet. Zones 6-9.
> Sibilla Mophead - trade gallon
Hydrangea macrophylla ’Sibilla’ (’Sibylla’, ’Sybilla’, etc) is a small to medium sized hydrangea that we originally got from Mrs. Bullivant at Stourton House, U.K. According to the Mallets it is synonymous with ’Masja’. It has dark, glossy leaves and fine flowerheads that are either a deep red or a fine dark purple (blue), again depending on the available aluminum in the soil where it is grown. Height to 3 - 4 feet, spreading as wide. Zones 6 - 9.
