Planting flowering annuals and perennials in the landscape. New posts are Florida gardening with the hydrangeas and some others being from the north.

The Nikko Blue Hydrangea

Nikko Blue Hydrangea Shrub

I’ve always heard the Nikko blue hydrangea mentioned when speaking of the blue varieties so I thought I’d look into it. First of all, the Nikko blue will only be blue if the soil is very acidic. If you buy a Nikko blue and plant it in dirt that has a lot of lime or high alkalinity your flowers will most likely be pink. Blooms are rounded and of the mophead variety.

As with many other types of hydrangeas, this one can grow in the shade and should actually be given some shade if you live in a hot climate. I think this is the type that was planted in the front yard of my rental. It would droop on hot days as the afternoon sun beat down on the yard and I’d have to water it often in summer.  They bloom in Spring / Summer and have long lasting bloom.  Be careful about pruning as the new blooms grow on old wood.  Don’t trim them up in Spring and remove all the new buds!

Many mail order nurseries carry this one as it’s one of the best known.  I suggest checking locally for a larger size plant, since the mail order ones are small.

Honestly, this type of hydrangea has tons of info.  Just google it and you’ll see.

Brown Spots on Hydrangea Leaves

What's Wrong?

I have not grown my own hydrangeas, but I did help care for the shrub in the front yard at my rental home. The landlady did not have a green thumb, and since the plant was not really mine, I generally just made sure it got enough water so I could photograph the blooms in summer and fall.

My last year living there, I noticed that part of the plant was not as green as the rest and some of the leaves were getting brown (see photo).

I no longer live there, but I’d like to know what this is for when I do grown my own hydrangeas.

Certain types of hydrangea shrubs can get diseases and have problems with powdery mildew, and mineral deficiencies. They can be affected by mites, aphids and Japanese beetles.

In fact the yard was full of grubs which turn into Japanese beetles and although I did seem some beetles on this plant, they didn’t seem to be doing much damage.

So why are the leaves turning brown? And only on a portion of the plant? Could it be Cercospora leafspot or some other similar fungus? Continue reading “Brown Spots on Hydrangea Leaves”

All About the Pinky Winky

Hydrangea 'Pinky Winky' The Pinky Winky hydrangea is not one you will easily forget. The flowers are pretty shades of pink and white and the shrub itself can be eight feet tall. Plant this one someplace where it has room to branch out. It is a paniculata and is a sister of sorts to the “Limelight” hydrangea which also has cone shaped flowers, but they turn a light green.

Paniculatas are hardy and the flowers form on new wood – or new stems, and that means the pruning – if needed – should be done in late winter or very early Spring before the new buds set. This shrub will bloom in summer and into Fall, like many hydrangea varieties.

As you can see from the photo I’ve added (not mine), the blooms start off mostly white and fill out along the tall spire, shaped like a Christmas tree.  Later the flowers will change color to pink.  See a good picture of them at the Proven Winners site.

Remember to plant this one in either sun or partial shade, but the ground should be moist and cool.  That is what most hydrangeas seem to like.

I look forward to growing my own this year, and then I’ll add my own photos.

Propagating Hydangrangeas Could Be Easier Than You Think

Create another shrub easily.

Most people think of starting a new hydrangea plant from a cutting, but I am talking about propagating by root or ground layering here – and it’s especially easy if it’s been done for you by mother nature.

My new yard has no hydrangeas, except for the tiny ones I planted this fall. But the duplex I rented for three years had a large, beautiful bush right outside my front window.

As I was weeding around it one spring I found a low hanging branch that had rooted itself into the dirt. I dug it up (with permission from the landlady) and replanted it near the front steps.

The following year she had another little hydrangea shrub to decorate her yard – for free! All it took was digging and watering.  It’s an easy, and super cheap, way to increase the beauty of your landscape.  And you’ll know exactly what you are getting!

Read the full story with photos by clicking here.  And check those low lying branches this Spring – it’s coming.

The Green Flowers of the Limelight Hydrangea

The Limelight hydrangea (paniculata) is popular for it’s size and stunning, large white flowers that become light green.  The shrub will grow to be very large (8-9 feet tall and can be pruned into a tree) and the blooms last from mid-summer through Fall when the flowers may change color becoming pinkish.

The best thing about hydrangeas, besides their huge flowers, color variety (as if that wasn’t enough!) is their long lasting blooms.  Does any other flower last as long?  I can’t think of one.  And then in fall, the flowers can be dried to last all winter.  Show me something better!

I don’t know much about the limelight hydrangea, so I am finding out.

  • It is hardy in zones 3-8
  • Very hardy and can withstand drought conditions once established
  • Flower color can’t be changed by soil amendments
  • Flowers are held upright on the end of stems (no dragging on the ground)
  • Flowers bloom on new wood
  • Likes sun or part shade

Perennial Flowers That Like Shade

I’d like to write about tall perennials that like shade, but I haven’t come across any. 

The best flower for shade is the astilbe (shown).  It has pretty leaves and shoots up tall, colorful and feathery-looking flowers.  It is available in many colors and I especially love the white.  But the flowers are tall and not necessarily the actual plant.

Other Shade-loving Perennials

Hostas are also well known as shade loving plants, but they grow close to the ground with tall shoots that hold their tiny flowers. This is a little “mouse ear” Hosta I planted.

Another favorite for the shade is the bleeding heart.

Of course many hydrangeas can do well in partly shaded locations and I plan to try some in my front yard (New Hampshire).  The truth is that most flowering plants need a lot of sun to look good, but arranging the plants I have mentioned here in a grouping beneath trees, or in any shaded area, can be beautiful as well.
