I fell in love with this climber, trialled in our garden and greenhouse last summer.

First come the delicate flowers, then the green balloon seedpods, each one holding a black seed inside marked with a perfect white heart – hence, its common name Love-in-a-puff.

Of the five seedlings I originally ordered only one survived. These were kindly replaced by the SR team, and of the next five another two collapsed; so out of 10 seedlings only 4 healthy specimens survived. However these have been fantastic, and are currently romping away over a series of arches and look great. I'm not sure I'll order these again, though, with such a high failure rate.

I literally could not resist this gorgeous plant and bought 5 seedlings. Only 2 have survived to date. I grew them on in pots in a nice, sunny-ish, sheltered position (that sounds so gardeny and competent doesn't it? It really means they were on the windowsill and then the garden table until they got big enough to plant out!). The failures just sort of keeled over, no idea why. The 2 survivors are in the garden, one is about a foot tall now - fingers crossed!
