the lobelia grows to 60-80 cm tall and I have only ever managed to keep them for a couple of years. don't know why I lost them it was nt a hard winter.
the angel wings grows to about 45cm and prefers full sun. but I haven't grown it.

Thank you for your reply, Seaburngirl.

Hi, Lobelia speciosum likes moist soil,{even boggy], in full sun or partial shade in a sheltered position, Derek.

If this is a haspen lobelia a sadly neglected garden plant as it doesn't last. In the second year given a enough root space I would say mine are 4ft now .I've seen them at 5ft in large terracotta containers these are very cheap to buy at long acres in bagshot but don't think will last much past

Thank you for your help. I have light sandy soil so will have to put in a lot of compost when I plant & perhaps some water holding granules. I certainly have no bog conditions. I think they should tell you more at these Gdn Centres but obviously they want to sell & don't tell you that you might not keep things very long. I shall just have to wait & see. Will try & protect through the winter.

Hi, as you say, there should be more information on the label, but unfortunately, it's not in their interest to let you know that you may not have the right conditions, in case they lose a sale, I actually think they would get more repeat sales, if they gave more information, and people wouldn't be disappointed, so return for more plants, but they're just interested in the here and now, Derek.

I lost the Lobelia speciosum after it’s first year , when it looked really nice.
