My thistles and teasle seem to prefer to grow where they decide to self seed and not where I plant them and fuss over them. However I did sow originals into open ground. My soil is quite poor and sandy. It is both anoying and rewarding to grow plants that seem to thrive when left to their own devices. So get the first ones going and then leave them alone.

I won't hit it with you right away but I have, at the bottom of this message, given you a list of 37 plants which have the word "thistle" in their common name. Not only that, although most of them are from the family Compositae, a couple of them are even from different families (Labiatae and Chenopodiaceae). Does it make a difference? Well you are talking to a newbie seed sower here who has just taken delivery of a clutch of packets from Chiltern Seeds. A select few of these packets had very specific instructions stuck to them. It seems that the seeds of certain plants will not germinate unless their biological processes are activated with moisture and moderate warmth and then they are banished into near freezing temperatures for a goodly while. This period of cold is apparently essential to their metabolism and it is only after they have endured this that they can gird their loins for their final Oom Pah Pah in conditions resembling the coming of Spring with its warmth. Looking it up, I can deduce that Echinops ritro (Globe thistle - the one you identified) is one such plant and should be sown in a cold frame. Whether or not it first of all needs a wake up call with the damp and not quite so cold (Lets pretend it's Autumn?) I have no idea. I have a little text file which I transcribed from the label on Chilterns seeds which I have dubbed "Chiltern's cold seeds" I think if you want to start them off immediately I would recommend you follow it. Chiltern cold seeds: 1. 64 - 72 F 2/4 wks 17 - 22 C 2. 25 - 40 F 4/6 wks -4 - 4 C 3. Return to to more than 65 F 19 C Indeed, if the seeds don't sprout the first season you are strongly advised to leave them to experience the full cycle of temperature environments and expect them to emerge the following year. To avoid stress for myself and thereby probably the plants too, each of my 3.5" pots is enclosed in its little greenhouse consisting of a clear polythene sandwich bag tied tight closed with a wire tie (often supplied with the bags) but leaving a fair amount of air inside the bubble. In this way I can be sure that they will never (or scarcely ever) need watering. However, because this is an ideal environment for fungii and other pathogens I also intend giving them a treatment of Cheshunts Compound as recommended. Which medium to use seems controversial. Chiltern seeds say that the success rate with Levington's Peat based compost far exceeds John Innes loam based. Maybe the objection to Levington's is based on environmental principles (the ransacking of peat bogs). My kitchen table seems to have been transformed to a potting bench! As for the "few other thistles" - well maybe one of them is the Scotch Thistle (Onopordum acanthium) (which, in cultivation, I would regard as more exotic than the Echinops). It seems that can be sown in Spring and do without the near freeze. Please remember that I said I'm a newbie and you should take the advice of any of the seasoned gardeners who respond to you if their advice is contrary to that I have given you. Respect Hussein - the list follows!

writes Hussein - the list follows! That's a fascinating list of thistles Hussein and it illustrates how much variation occurs under common or popular name descriptions of plants. RHS Plantfinder CD 2000/01 gives an even wider range of plants with 'thistle' in their name including six varieties of Globe Thistle, most of which are listed as echinops. I have always thought of Globe Artichokes, Cynara scolymus and Cardoon, Cynara cardunculus as edible relatives of the common garden thistle, Cirsium vulgare. They are in the compositae family, but none of the five varieties of Cynara listed in Plantfinder have 'thistle' in their name. What all of those plants share is vigour and hardiness, welcome enough in cropping, but less so in decorative gardening. -- Alan & Joan Gould - North Lincs. |

For an overview see URL:http://www.mobot.org/MOBOT/Research/...ers/asteralesw eb.htm#Asteraceae Elsewhere, not only has Liliaceae been chopped into lots of little pieces, as previously proposed, but it's spread across two orders (into one of which Orchidaceae is sunk). Or for my summary on Malvaceae, see http://www.meden.demon.co.uk/Malvace.../overview.html http://www.meden.demon.co.uk/Malvace...ttneriina.html http://www.meden.demon.co.uk/Malvace...alvatheca.html tho' I haven't incorporated recent data on Hibiscus, Pavonia, etc. I stumbled across a suggestion that Veronica will swallow Hebe and Parahebe yesterday evening. -- Stewart Robert Hinsley |

The Cruciferae family, particularly the brassicaceae are long overdue for revision and re-classification IMHO. Extensive sequencing of individual species mostly applies to crop plants (e.g. rice, cotton), but also to thale cress (Arabidopsis thaliana) which is used as a model plant in the study of plant developmental biology. Beyond that there is a bias towards the wild relatives of crop plants (e.g. plenty of sequences of wild cottons), and to recently described species (presumably because the researchers have material to hand). In several groups well known ornamentals are missing from the set of species for which sequences are published (e.g. H. syriacus and H. mutabilis in Hibiscus). Take a look at EMBL/DDBJ or Genbank. PS: Cruciferae and Brassicaceae are one and the same, with Capparaceae/Capparidaceae sunk therein in recent classifications. -- Stewart Robert Hinsley http://www.meden.demon.co.uk/Malvace...directory.html |

Cardueae and Lactuceae (or Cichorieae) are subdivisions of Compositae; I took that as understood. Asteraceae and Compositae are the same. [The current rules are that family names are derived from generic names, but some old family names are grandfathered in Leguminosae = Fabaceae Guttiferae = Hypericaceae Graminales = Poaceae Labiatae = Lamiaceae Compositae = Asteraceae Cruciferae = Brassicaceae Umbelliferae = Apiaceae and any more I've forgotten.] -- Stewart Robert Hinsley |

The message
from Hussein M. contains these words: I also suppose that the best time to sow any seed in situ is that time when the plant seeded to produce the seeds. Well...no, it isn't, especially in areas which have cold or wet winters. Autumn-sown open ground seeds usually have far lower germination and poorer survival rates than the same seeds properly stored, then planted in the same place in Spring. Seeds in open ground do better when soil is warming up not cooling down, and when daylength is lengthening not shortening. Janet. |

You might remember more than one discussion in urg about 'collards' and others about correct naming of broccoli/calabrese. New gardeners are often caught out by rooted plants being brassicas and Oriental mustards are becoming a minefield of their own. Normally recreational gardeners do not concern themselves over much about correct botanical naming. When vegetables are being grown in a rotational system though, plant families, especially brassicas can be very important in maintaining soil and plant health. -- Alan & Joan Gould - North Lincs. |

I don't know which plant you mean by collards, any more than I know which plant you would mean by 'gillyflower'.

The point I have already made is that whatever the common name of a plant may be, or for that matter whatever its taxonomic name is, a gardener needs to know which plant family it belongs to in order to carry out correct crop rotations. A new system of classification could take the opportunity of making that a lot more clear than it presently is. Brassicas are more relevant in that respect because they collectively tend to take the highest proportion of area in an average vegetable plot, and they have the greatest number of varieties within their family compared to other vegetables. They are also susceptible to club root if grown too often in the same place or too intensively, and that horrible disease can take up to nine years to eradicate. -- Alan & Joan Gould - North Lincs. |

Rome wasn't built in a day and developing that intuitive sense of what works and what doesn't (aka a green thumb), as regards seed sowing or any other aspect of avocational horticulture, takes time -- and any number of humiliatingly abject failures. Generally speaking, I find that seeds of composites (Asteraceae) and labiates (Lamiaceae) do better if held back until normal planting out time in the spring, or maybe a few weeks earlier. They seem to require warmth for germination, and if sown now, tend to simply rot away during the long, dark, damp, chilly winter. [Note that this is not a Rule engraved on a stone tablet; rather it is simply what I have experienced under my conditions and preferred practices. YMMV etc.] On the other hand, cyclamen should be sown as you can. If you delay, their germination may be delayed a full year, as most species tend to germinate at the same season as mature plants leaf out. On the whole, I prefer the approach of letting the seed germinate when it will rather than *making* it germinate when I want it to. This helps avoid the difficulty of trying to over-winter young seedlings. You'll also learn tricks like topdressing seed pots with fine gravel, sprinkling fine seed on top of the top dressing and drawing it down via capillary action by standing the pot up to its neck in water, and so on. A very skilled seed sower here swears by a drench of a good fungicide such as captan. as making an enormous difference between success and failure with many seeds. As for your failures at sowing hardy perennials, dump the failures out where any chance later germinations can be rescued. There is one garden on the mountain slope that overlooks Vancouver, BC, where for years the owners have dumped out "failed" seed pots on the grassy verge of the street. The most astonishing assortment of plants has come up as a result. Just don't tell anyone what failed. Emphasize the successes. For the record I have a germination success rate somewhere around 60-75% pot-wise; and often if *anything* comes up in a pot, I o,ften get about 80% germination, seedwise. Of course, there are wide variations from year to year and pot to pot. -- Rodger Whitlock Victoria, British Columbia, Canada |

And this also applies in the second year - stick the failed pot under the staging, with just a plastic bag over it so you don't have to water it, forget it completely, and next spring, after a good cold spell, the seedlings may have come up like mustard and cress. Or they may not. -- Kay Easton Edward's earthworm page: http://www.scarboro.demon.co.uk/garden/ |

Since you are interested in hardy perennials, I suggest you investigate the seedlists of the RHS, the Hardy Plant Society, the Alpine Garden Society, and the Scottish Rock Garden Club. There's probably someone in your neighbourhood with a copy of each of these. [You must join the relevant society to get seeds from them, btw.] The HPS list is (or was when I was a member, ca. 1982-1994) exceptionally rich in herbaceous perennials, including a wide range of quite uncommon plants, and the seed packets were very generously filled. You might think the suggestion that you look into the AGS and SRGC list misguided, but these lists contain all sorts of interesting surprises in the way of perennials, by no means all "tiny gems from the rocky heights". -- Rodger Whitlock Victoria, British Columbia, Canada |
