Liriope muscari
Shoot User
Hi Iris and Laura,
Yes Liriope muscari flower throughout autumn. They prefer partial shade and acid soil, but tend not to be too fussy about this and can be grown in other conditions within reason. They can flourish without being fed at all, but if you want to, then an application of general purpose garden fertilizer in early spring can't do any harm. Be mindful not to feed them with a fertilizer that is higher in nitrogen, as this will encourage new foliage growth which may come at the expense of flowering.
What sort of conditions do you have yours in? It might be worth relocating them if they are in full sun or shade to somewhere offering more of a compromise.
Sometimes it simply takes these plants a while to settle in and get going. Some people cut or mow them down to the ground in late winter to renew vigour and encourage new growth. This might be worth a try if you have still not had any luck this year.
Hope this helps! Let us know how you get on.
Katy
