Neighbours talking over the garden gate has long been a tradition. They share gardening tips, complain about the weather and pests yet are ever eager to discuss their gardens. That is what I had in mind when creating this blog. So stop by my garden gate to find out the latest happenings in my garden.

Happy Gardening!

Velvetleaf (Abutilon theophrasti)

(Abutilon theophrasti)
August 25, 2010

As a gardener my style is not to get too bent out of shape with respect to weeds.  Some weeds act as companion plants in a garden while others are edible.  I only get concerned if the weeds present the potential to choke out the fruits or vegetables.  My preferred way of dealing with weeds is pulling.

Earlier this year I noticed a suspected weed that I had not seen before.  The plants were mainly in the two new raised beds so chances I thought the seeds might have been in the soil used to fill the beds.  They were appearing in numbers quite suggestive of a weed so at first I was pulling them before the plant got a about 9 - inches tall.  Then it dawned on me that I should identify the plant to be sure it was a weed and not a wildflower that I may want to transfer to another area of the garden.  I decided to let one grow a bit for identification. 

The plant is Velvetleaf (Abutilon theophrasti) is a member of the mallow family.  It is classified by Ontario Weeds as a weed that is mainly a problem in corn, soybean, and other tilled crop fields.  This weed can reach a height of 1 to 2 metres.  The broad heart shaped leaves result in overshadowing other plants.  The leaves on the one pictured in one of the pepper beds measures 8 - inches at the broadest point.  In corn fields a density of velvetleaf of 1 plant/m2 the loss is 4%  while in soybean fields the same density will result in a 6% loss1.  Clearly with respect to the cash crop sector this is a problem weed.  The good news is that velvetleaf is not toxic and not known to be allergenic so pulling this weed will not be an issue.  Velvetleaf also attracts beneficial pollinators.  It is acting somewhat as a companion plant with the peppers though if you notice the damaged leaves.  Whatever insect is doing the damage is going for the velvetleaf and leaving my peppers alone so the peppers are nice and healthy looking.  The seeds of velvetleaf are edible and at one time fibers from the plant were used in China. 

I would like to let one grow big enough to harvest the seeds to use as a companion plant next year.  With proper management by pulling before the plant has a chance to flower I can reap the benefits of the pest control without reducing yield.  This plant is just now started to flower.  My main concern is the plant is just too big to keep where it is.  What I'm going to try is potting up one of the smaller velvetleaf or may even transplant a couple to harvest the seeds.  While the plant is not classified as a noxious weed in Ontario it is in British Columbian and several US states so I will be using careful management with this weed.  As soon as the seed pods appear I will be bagging one or two and remove the rest so the seeds don't get out into the wild where they can be a problem.

Happy Gardening!

  1. Very interesting. :)

  2. for some reason this year we have tons of this in my garden. Have been looking online to see if there is a use for this weed. I will say that although it has now overgrown my whole garden due to my not weeding, it has helped a few of my tomoto plants survive this drought year we have had. I am hoping to let the pigs loose in the garden and see if they can help me dig up any that I dont weed out myself.

    The Japanese beetles love this "weed"! They will eat the leaves and leave the veggies alone. I'm going to let them grow and the next year plant them where I want them so they can be controlled. I also didn't have any hookworms on my tomatoes so I'm wondering if this helped with that, too. I'll be paying better attention next summer!

    If you plant more food for the Japanese beetles, I suspect you will just have more of them, at lease next year. I understand the idea of drawing them away from your desired crops, but I am not sure that giving them ample food will really accomplish what you want. -Carolyn, Indiana
