I was going to load this in the plants database, but I'm not sure which sub-type of achillea this falls under; the tag doesn't specify. Does anyone know?

Hello Gardenwife,

No sub-class involved. Just genera Achillea; species ptarmica; cultivar 'The Pearl'.

Here in the UK this lovely little Achillea was all the rage amongst enthusiasts in the 1960s

This grows quite well up here, but can be invasive. As with most yarrows, it throws underground runners and spreads rapidly. However, the tiny rose-like double flowers are really charming. I like to put it around borders where it will show nicely. If you put it in a bed with other plants, it can choke everything else out. It also has a tendancy to fall over sometimes, so staking may be necessary.

I get so confused as to what parts of the plant names go in genus/species/cultivar. Thank God for the ID forum and PDB here!

Yes, this surely is a great site for information. I've used the database to catalog many of my plants.

Hello Gardenwife - see what you make of the hyperlinks below. They may help you to get plant nomenclature fixed in your mind.

Write names down as they apply to the plants you grow after finding them from the forum or a search engine.

Natural Order - same meaning as 'family'
Genera - is the next division
Species - is the next division
Variety or/and Cultivar is the next division.

Varieties can be naturally found in nature or bred. Cultivars are bred.

Those are the major divisions - don't delve into further sub divisions and classes etc until you are clear on the above.

Peter63: That's some great information. I think lots of us will benefit from it. I have gotten confused myself sometimes, so I read up on the subject, then get confused again! I seem to keep it fairly straight until I get to the hybrids!

Peter - that IS great information. Thanks for posting this! I love the first one, especially; the "Plant Epithets" list is particularly interesting (though it sounded like something crocuses might utter, LOL).

Now, are you THE Peter of this site by Peter Dawson? If so, it's a great site! If not, it still is a great site and you're a nice chap for posting it. ;)

Aha! I figured it out when I saw his contributions to the PDB, and they were suspiciously identical to those in his plant portraits at his site. :D After writing a completely goofy, stumbling e-mail from his site, of course. ;)

Hello Gardenwife,

Yes, I am the guilty party. Peter; Peter63 and http://www.dwsn.fsnet.co.uk are all of a bundle.

Articles on the web site are created from my past horticultural experiences.

All photos are taken by myself either on visits to gardens or from my own past gardens. I do not now garden as I live in an apartment.

I know litte of data on the WWW but most forum users are conversant with using search engines such as Google and Copernic. Also those who wish to be guided to sites on particular subjects need go no further than MaVieRose who usually comes up with the goods. And I'm sure, other super-surfers also. I never seem to have the time to ride the waves.

Good gardening to all

Peter.
