What comes to mind when you think of your garden or the landscape in the fall? Not including all the work gardeners do in preparation for the coming winter, sit back and just meditate on all the things you associate with fall. My list was amazingly long and looking at it as a whole, it brought a rather peaceful happiness to me. Leaves played a very big part in my association with fall, as I expect the same will be true for others.

It’s that time of year when eastern white pines (Pinus strobus) start dropping older needles, resulting in a new layer of sound-cancelling padding under trees. The sight of so many browning needles can be alarming though if you are not wise to the true meaning of evergreen. In general, evergreen refers to plants whose leaves (broadleaf, needle-like, scale-like or awl-like) last more than one year before falling. Deciduous plants on the other hand drop all of their leaves, leaving the plant completely devoid of leaves for part of the year.

Hard to believe it’s just four weeks out from the St Louis area’s first median frost date (~October 10), so prepping outdoor perennial container plants for over-wintering has moved higher up on my priority to-do list.  Some are hardy perennials that I just planted in large containers with the intention transplanting them in the garden late summer, leaving enough time to become established before freezing temperatures arrive. 

I really can’t say enough bad things about mulberryweed, a.k.a. hairy crabweed (Fatoua villosa). For me, it has been a weed nightmare that come in on a load of mulch about 10 years ago, and every year since has been a battle to control because I didn’t recognize it for what it was and take action soon enough. Hand weeding or chemical control needs to be done immediately upon detection, and this can’t be stressed enough.

When you have a lot of any one thing, it’s sometimes hard to choose a single favorite, but in the case of tall bearded iris, ‘Edenite’ is the one I most look forward to every season.  Described as sooty red-black with brown beards, this historical 1958 release is still a crowd pleaser.  Unfortunately, it has been blooming rather infrequently the last few years due to shade development since its planting.  The rhizomes keep growing and the patch keeps getting larger, but no blooms.  Given that iris require six to eight hours of full sun during the growing season for best performance, some of
