Ok so this might be a simple question with the answer wait and see (which is what i'll probably do anyway).
Basically i got a packet of purple geranium seeds from T&M, as i thought i'd have a go, being a fan of hardy geraniums.
You only get 5 seeds per packet so i sowed them all. First one germinated quite quickly so i pricked it out and left the others too their business.
Now the first geranium is a reasonable size now in a 9cm pot, it's put on alot of growth and has about a dozen decent sized leaves. But you guessed it, their not purple, not even a hint of purple, they look like most other hardy geraniun leaves. Is this normal? Do they often develop the colour as they mature, not sure why but i thought they would be like purple lettuce which pretty much are purple from day 1.
A second has germinated now, but is only at the cotyledon stage so can't tell if it looks the same yet.. we shall see.
Even if the plant isn't purple i'll grow it on and see what it's like as it'll most likely be nice, even green and i've plenty of space in the garden for more geraniums. You never know maybe it'll turn purple
