4 - 6'
4 - 6'
5 - 9 (-20 degrees F)
Medium green ovate leaves 4-6" long.

Red Hydrangeas require alkaline soil. Aluminum is a component of all soils, but its availability to plants depends on the acidity of the soil.
Well drained humus rich, alkaline soil. If you have acidic soil, add lime to acid soils to make less acidic.
Moderate to fast. Slower in the North regions.
Flower buds develop on old (mature) wood of the previous year. Can dry bloom heads for added interest indoors.
None necessary. May wish to shape if desired.

Just received the plants today. I ordered 5 red hydrangea. I am quite happy... small plants but lots of leaves and healthy looking. I can't wait to see them grow :)

I. bought a special group package about 5-6 years ago,witch included. A red, niko blue, an annabell white and a pink. They now range in size from about 12"x12" to 36"x36". Not exactly what I had expected! The largest one is the Niko blue and it is truly beautiful!!!, but it will be years before the little ones bloom, so I have no idea what a red bloom looks like. While the catalog does not tell you this, you can bring up "red hydrangea" on Mich bulb web site and scroll to the bottom, you will find very helpful info including --add. Lime to your soil to get the red color.
