My father-in-law has an amazing garden - plain and simple. His passions are rhododendrons and azaleas with a small smidgen reserved for dogwoods. He once estimated that he had about 140 azalea bushes and 60 rhododendrons in his yard - and they all bloom at different times throughout spring and summer... and if we are lucky and have a warm spell in winter, we have a few that pop up then as well.
This is my current favourite in the backyard:
I think it would be impossible to have an all over favourite since your choices change every few weeks.
Here is a close up of one of the dogwoods:
And a magenta azalea:
Another flowering dogwood - this one in the front yard:
A mauve rhododendron in the front:
A dark rose-pink azalea in front of the bay window:
And some more flowers to add to the Project Spectrum pile:
A yellow magnolia:
We have lived in Delaware for five years now, the first three of which were in this very house... and I am a little embarassed to admit that I didn't know until today that there was a yellow magnolia in the yard!
A yellow and orange azalea:
A pink and yellow rhododendron:
Another yellow rhododendron:
A very cool coral-red and yellow rhododendron:
And this, my friends, is only the beginning of the best season for my father-in-law's garden.
