Rose Cutting - One of the leaves that has sprouted has 7 'leaves'
I'm hoping that someone can help me, a couple of months ago I took rose cuttings for the first time and they are coming along nicely, or so I thought until I saw my favourite one looking like this... I've read that they should have 5 leaves and if they have 7 they are the suckers...? Any advice would be greatly appreciated.

Let us know how you get on.
The main reason why Roses are sold grafted is because grafting onto a strong rootstock makes the rose plant grow faster, due to having roots already in place, and be of a saleable size much sooner.
Own root roses will take longer to develop but, at least going from what I’ve read, they will eventually meet or surpass the size and performance of the grafted variety. Just take a bit longer to get there.
You also don’t need to worry about suckers from the rootstock or the potential for the graft to fail.
So grafting is mainly for the convenience of the breeder/seller - in allowing them to grow a greater numbers of roses to sell in less time.
It makes some roses more tolerant to wider soil conditions because rosa canina 'laxa' can tolerate alkaline soils (which many roses can't, for example roses with multiflora genes) and also wide range of drainage/soil type and climatic conditions. It makes the grafted rose much more universal or adaptable.
It also changes the character of the rose somewhat, passing some disease resistance and growth patterns. They are two roses in one and they both have an effect on each other.
These points together mean that rootstock makes the behaviour of new rose varieties significantly more predictable and makes them easier to grow.
Grafting is a good skill to learn if someone wants to grow a lot of cuttings or roses from seeds (either selectively breeding or just using seeds from open-pollinated hips, these will produce completely new varieties, which can be fun but also a lot of trial and error).
