photinia x fraseri - different heights?

went to my local b&q.
saw 2 pots of the same photinia x fraseri (that is, if the label is to be believed).

one label stated the maximum height of plant would be 2m.
the other label stated the maximum height to be 3m.

is this correct?
can the same plant specimen be grown in such a way that it will grow to different heights?

or is it just a case of badly printed labels?

need i say that the b&q staff were clueless?!

so, anyone here know the answer?

if there is a difference, then i'd like to know up front as i want the taller growing one to form a higher screening hedge.

thank you.

 

that clip shows 12 ft photinias!

loofah - i have read the RHS site previously.
and that, along with the b&q labels, have thoroughly confused me!

is there only 1 type of photinia x fraseri or multiple types?
how can i find out?

b&q have a reduced price offer for the "2m" photinias - i think it is 2 for £12.
whereas the "3m" photinias are about £14 each.

so, do i just try & see with the "2m" ones?
tho, waiting say 5 years for them to grow and then finding out they aren't tall enough would be a bummer.

 

There are different Photinias.....red robin, a dwarf form, a variegated form, etc. check the
Labels carefully.they may also be from different suppliers with different opinions as to eventual size. Photinia red robin is vigorous and 3 metres is easily achieved. They can be pruned though

 

yes, i did triple check the labels. both sets were tagged as "photinia x fraseri" and underneath "red robin".

 

I think your 2 metre plants will grow to height you want. Seems good value too. Incidentally, did leaves look same ? Were they smaller on 2 metre plants?

 

not the best of photos but you can see the 2 plants next to each other.

the "2 for £12" is the one with the label stating it will reach a maximum height of 2m. that is a 3L pot.

the one to the left of it is a 2L pot and its label states a maximum height of 3m. that is selling for £8 each.

(side note: gave the wrong price for the 2L pot in #3. sorry.)

both pots have "photinia red robin" on the front of the tags.
and both have "photinia x fraseri" on the back of the tags.

as far as i can see, both leaves seem to be similar size / shape.

ok, i've taken the plunge and gone for the 2 for £12 deal.
what i might do is raise the floor level just a tad, so even if the plant only hits 2m, it'll be tall enough for my needs.

nothing else to do but wait a few years and see what happens.

 

I wouldn't raise floor level kamchow. I'm sure they will,hit 2 metres inside 3 years. Making sure the soil is enriched and well fed for at least double the size of the pot will help produce good strong growth. I find Photinias make rapid growth in their second year.
