Name:Hydrangea macrophylla also commonly referred to as: hydrangea or hortensia
Description: Hydrangeas are gorgeous bushes bearing large flowers throughout the summer.
Flowers are a large rounded flower cluster, or 'lacecap' with a center of smaller flowers surrounded by larger petaled flowers.
Flowers can be either white, blue or pink, the colour depending on the soil type.
Size: 24 inches to 6 feet.
Conditions: Hydrangeas are easy to grow, but the soil should be well drained.
They need lots of water, so water once per week or more.
Hydrangeas can grow in full sun if watered well, but will bloom better in partial shade.
Avoid planting it in hot, dry, exposed places.
To plant, dig a hole about two feet across and one foot deep.
Hydrangea plants grow in a wide variety of soils although rich moist soil is best.
Use a general-purpose fertilizer, and add 2 cups per 100 square feet in March through July in the Northern Hemisphere (Springtime) - or September to January in the Southern Hemisphere.
Water soon after application to help dissolve and send the fertiliser into the soil.
Pruning is the most essential.
Prune only the stems that produced this year's flowers; otherwise you will not have blooms next year.
Propagation: Take a cutting from about 5-6" (about 15cm) long branch.
Remove lower leaves, and cut largest leaves down to about half their size
Dip cuttings in rooting hormone and place into damp vermiculite, or coarse sand.
Water well and allow to drain. Make sure the soil is moist but not soggy.
Cover pot with plastic but keep plastic from touching leaves, add bamboo stakes if needed.
