Nothing ventured, nothing gained. As the " mother " plants should be cut down close to ground level after flowering. I would try potting these up, i would reduce their leaves by two thirds water little , often and hope.

I do not know if that is the thing to do, but I would unless told different.

I dont cut mine down at all as some of mine a semi evergreen. The dead foliage is easily pulled away in spring. the foliage provides winter protection too.
in the past I have planted these 'plantlets' straight into pots of good compost. I usually cut about 1/2" below the plantlet and keep them on the dry side of damp [if that makes sense] so roots are encouraged to grow. They are fully hardy so I leave mine down the side of the green house or in the cold frame if I have space.

one of the plantlets has a brown swelling visible in the photo, thats the new root forming. They should all take. so enjoy plants for free.

Mine haven't produced any plantlets - do all the varieties do it, or am I not doing something I should?

Some kinds produce more than others, Steragram, but it is still something considered a bit unusual. Higher nitrogen levels result in more plantlets, as does hot, humid weather.

Hey, thanx all..knew I'd find an answer from some of you on this site, cheers!! j :-)

Mine did this a couple of years ago. I just took them off, potted them into 5" pots, watered them and put them in a sheltered spot until they had rooted then planted them out. I did nothing special and they all grew into nice new plants which flowered the following year.

Thanks Tug, that explains it - no high nitrogen and cool weather!

Throw on that Icelandic sweater, and enjoy it, Steragram! : D

I'd better tell the day lilies the same thing!
