will oldhamii's culms leaf back out?
I have had some Oldhamii in the ground for about four years or more and each year here in central TX it loses most all of its leaves due to brief freezing temps. The culms remain a healthy deep green but the outer branches usually turn light brown so that part is certainly dead. But i've always waited till mid-summer before accepting that these deep green culms are not going to put out any branches or leaves. Right now for the past month new smaller shoots have shot up from the ground and some of the bases of the smaller culms from last year are sending out dense clusters of new branches. So even though these larger culms from last year look healthy should I just cut them out now? Are they inhibiting other culm growth in any way?
