Wow! This sunflower has really blown us all away.
There was no difficulty tracking down Dolores McAllister's home in south Belfast - it was surrounded by gigantic bobbing sunflowers!
Measuring her tallest sunflower for our Blooming Marvellous sunflower growing competition was a little more of a challenge as it was far too tall to reach with the tape measure.
When we scaled those dizzy heights, the sunflower clocked up an incredible 9ft 6in, which means it is 52 inches taller than Environment Correspondent Linda Stewart, who is 5ft 2in.
Dolores admits to being something of a sunflower obsessive, so it's no wonder she has cracked the technique.
The retired English teacher says: "I've been growing them for maybe 15 years. It dates back to when I first went to France, to the Vendee, and I was mesmerised by all the sunflowers.
"From planting them as little seeds to watching them grow, I love them so much.
"I use the seeds from the year before. The big killer at the beginning is keeping the slugs away. If you can get them to a foot high, they are generally OK.
"You have to stake them because they grow too big. Some other years when there was lots of wind, I would have been out covering them all with big canvas things to stop them from being wrecked. Everybody loves them."
Dolores says she has given lots of sunflowers away to friends and neighbours but they never seem to grow as big.
"I think they are not as obsessed by them!" she says.
