Looking for front yard landscaping guidance

[DC15]

I have a patch of 5m X 3.2 in the front yard which I'd like to do up so I can plant some roses and other flowers. Before planting anything, I'd like to first structure it out with some garden edging and concrete sleepers in 2 rows. I have attached a plan I've put together.  I wouldn't want to cut the concrete sleepers, so looking to put sleepers that would best fit in the space like Pioneer 200 x 75mm Ironbark Reinforced Concrete Sleeper which are available in 2m and 2.4m sizes

• Planning to start off with some garden edging like Matrix 400 x 900mm Charcoal Foliage Garden Edging at the furthest end. Would like ideas here.
• Then use concrete sleepers in a U shape to plant flowers around. Wondering if Jack 50 x 450mm Galvanised Steel Retain It Corner Post Upright Sleeper would serve the purpose? 
• Next I'd like to paint the posts so they don't standout due to the aluminium look. Not sure which paint to use with Ironbark sleepers.
• Any fillers to fill the gaps between the sleepers and posts for the sleepers to be held firmly in the posts?

Would appreciate suggestions and improvements on how to go about this plan or any other ideas on better ways of doing the frontyard

Hi @DC15,

I just wanted to place some before and after photos right next to each other so I could really take in how impressive the transformation is, even without the flowers being in full bloom just yet.

Now that they are blooming, you would surely have the most beautiful front garden in the entire neighbourhood. Truly a paradise for bees and pollinators.

You've done a truly fantastic job and I'm glad that Dave and myslef could play a small part in helping you along the way.

Thank you for sharing such a fantastic transformation.

Thanks @Dave-1  for the tip on crepe myrtle. I'll keep that in mind.

If I would do it again, I might keep more room around the tap to make it easier to fit in a bucket and use slightly taller edging
