Trachelospermum jasminoides

I have admired the white variety in other people's gardens and started looking online at prices and sizes. I see there is a pink variety and a lovely-looking pale yellow (and a collection of all three available; tempting!). Does anyone know if they all grow at the same rate please? My plan would be to grow them up a pair of obelisks, so a similar rate of growth would be helpful. 
Thank you.
