Invasive plants to avoid

Posted: 31/07/2012 at 20:43

Alchemilla alpina, erythropoda and faroensis I have grown and whilst they will spread from seed they are not as invasive as mollis.

Another real spreading thug is Allium ostrowskianum which comes in different names, like A. farreri and oreophilum. No matter what the name it is a  SPREADER.

Now Alstromeiria do not survive in our garden, too cold we think.

Another set of plants to plant with caution are any of the perennial Helianthus. They can spread widely if suited.

Another seed weed, if allowed is Knautia macedonica and as for Aquilegias.................I have decided that I am removing every plant of this as I can no longer keep up with the weeding. One missed seed head and the place is crawling witrh them again. And before the 'I love them brigade' jump on me, the seedlings are small flowered nondescript wishy washy coloured things.

Forgot another one, Solidago, that also seeds itself everywhere if not cut down.

Saponaria officinalis is a real thug. and I wish Lysimachia Firecrackere WAS easy to remove. I have been trying to get rid of it from one area for 4 years now, digging it out and putting Weedkiller on every time there is a new leaf showing.

Campanula takesimana is a seed weed of the first order, deasd head it assiduously.

Viburnum Bodnantense. " Dawn".

Creeping thyme (Thymus serpyllum)

Posted: 30/07/2012 at 15:01

Most Garden Centres sell a reasonable selection of different Thymes. But, do be aware that there are some which make quite substantial busshes rather than creeping along the floor. For example Lemon scentted Thyme makes a 12 inches tall bush. For in between paving slabs you want forms of T. serpyllum, of which there are a lot of varieties in reds, pinks and white and with different leaf colours.

What is it

Sounds like a Squash rather than a Courgette.

Concrete layer in flower bed area - what can I do?

Posted: 30/07/2012 at 12:50

We have an area of concrete, the size of two old cottages, so fairly substantial. Some of it we have gravelled and use as a seating area in  with a Gazebo. However, the rest I coverd with top soil, held in place by large boulders, so in effect a raised bed. The soil depth is about 18 inces or so. I have filled it mainly with herbaceous stuff. Round the edge of the gravel area I planted Bamboo and Miscanthus of a giant form. the concrrete has stopped them from becoming too invasive.


We did find another area which had a concrete base of about 2m by 1m. We guessed that it was the base of an old outsoor toilet. No drains, just a bucket to be meptied onto the garden eventually. That we did remove. Underneath it was a huge mass of small boulders. I used them to make the raised beds. Even worse was the area in front of it had a deep pit which was where the cottagers had put all their broen glass and potters. I only managed to clear the top 2 feet of that and it was still gong down. Hope you area is just the base of say a coal bunker.
