Id Please

Could be Jerusalem artichoke (Helianthus tuberosus).  They tend to grow quite tall and have a nutty flavoured tuber which is good for eating!  Give it a quick Google and see what you think.

Any suggestions as to what this might be? Thank you.

Flowering and day length - streetlights?

Posted: 13/08/2015 at 01:11

Certainly, artificial light will have an impact on some indoor plants (such as christmas cactus and poinsettia) which are called "short day plants".  These need a maximum continuous period of darkness (approx. 14 hours) to induce flower bud formation.  Even a brief flash of light will prevent this as it causes a chemical in the plant (called phytochrome) to change its molecular shape which then inhibits the chemical processes to form the buds.  However, it is the red and infra-red ends of the spectrum which are involved (not UV).  Growers for the Christmas market use computerised systems in their greenhouses to ensure that such short day plants only receive the light which they need.

I would doubt that the intensity of street lights would have much effect on the doorstep chrysanthemums however!  Hope that helps.

If you are referring to the large leaved plant making up most of the photo, then that is Acanthus mollis (bears' breeches).

Many thanks yarrow2.  Itea virginica certainly seems to fit the bill ~ I have never heard of / come across this plant before but really appreciate your swift response.

Again, from my new garden, any help in identifying this white flowered shrub would be appreciated.  Currently, it is about 1m high and, during the winter, its leaves were rather red.  Thanks in advance!

Fluffy white stuff on my crab apple and wilted leaves - help!

Definitely woolly aphid!  Have a look at the RHS link below which suggests different methods of control (both biological & chemical)

Plant DNA

I would agree with all of the above in that you will never get a female plant from cuttings of a male plant.  One exception would be in the case of variegated plants which have arisen because of a mutation in the plant's DNA.  Breeders then propagate these from cuttings to produce identical plants with variegated leaves.  However, sometimes, "reversion" occurs which means that some shoots of the plant turn all green again.  This is because (it is thought) some of these mutations are unstable and just one part of the plant becomes affected.  In effect, therefore, you will have a single plant which has different DNA in different parts!  Typically, if you do not cut out all the green shoots, the whole plant reverts back to normal as the leaves / shoots with more chlorophyll will grow faster and out compete the variegated ones.  Hope all that makes sense!
