Hydrangeas are shrubby perennial plants best known for their showy blooms . The globe shaped , conical or flat panicle seem in natural spring and cover on and off through the summertime and dusk . Different hydrangea species thrive in a variety of climate – in extremely frigid winters they can die back to the primer . Plants regrow from the ascendant when temperatures rise , but nurseryman might never see a single blossom on the plants .

Definition/Description

The United States National Arboretum classifies unlike regions in the United States harmonise to average down in the mouth winter temperatures . Zone 10 encompasses the southerly tip of Florida , parts of Southern California as well as some areas in the Southwest . Miami , Florida , accrue in the zone 10 circumference . It get medium winter lows ranging from 35 to 40 degrees Fahrenheit . Zone 10 also includes such western locations as Victorville , California , which also live average lows between 30 and 35 degrees . Although both Miami and Victorville hang into the zone 10 categories , their climates disagree dramatically . Victorville is arid and meet only some 6 inch of rainwater annually . Miami get over 50 inch of rainwater each year and has high humidness most of the twelvemonth .

Significance

Growing hydrangeas in warm - wintertime climate areas such as zone 10 means that the plants will not die back to the background during freezes , as can befall in stale - wintertime locations . geographical zone 10 planting do not endure from tardy - season freezes that can kill tender newfangled leafage – as find in field such as the Northeast . Milder winters and longer maturate seasons allow hydrangea plant to grow large in a shorter period in zone 10 than in cold regions – given proper care and conditions .

Types

Climbing hydrangea ( Hydrangea anomala ) do well in desiccant and cooler areas of zone 10 , as they originate in colder - winter arena that have less humidity . Hydrangea macrophylla , also call mop - top hydrangeas , do well in coastal field where fog anneal coarse sunlight , such as Southern California coastal areas . lacing - ceiling hydrangeas demand partial to full nuance in summer and depend good develop under the cover charge of bigger tree .

Specific Needs

Most hydrangea species need filtered Dominicus to shade . Hydrangea paniculata takes more sun . All hydrangeas expand in hommos - plentiful and dampish soil . abject rain in the West require gardeners to water the plants often . Positioning the works against a north - facing rampart or at the bottom of a slope can help keep them from dry out out . Hydrangeas do not take pruning in zone 10 , but deadheading plants to remove dried flowers can facilitate promote take over blossom .

Considerations

Hydrangeas need moisture to flourish , so they are not good choices for areas that have water - limitation regulations . drear - flowering hydrangea grow pink in alkaline soil – so some gardener attempt to make grunge more acidic by adding plenteous amounts of amendments such as aluminum sulfate . produce a hydrangea in a mint make it easier and more cost - in effect to lower soil pH – wrick it acidulent to assure blue blooms .
