Well I had to buy these... the names, the names.
Alicia is our newest Grandchild - just over a month old now. I suddenly had an excuse to buy these - I'd spotted Alicia before but the name had never had a connection before. So I got three of each. When you can afford it you need to buy plants in odd number sets.
1 plant is a specimen plant - okay if it is going to be a huge special plant.
2 plants ... with the space between - turns into a line which isn't like a clump of colour. Straight lines never seem to work well in an actual garden because plants are floppy and never quite fit the plan, except in the vegetable garden. Then lines look better because you have go in a hoe.
3 - yep forms a clump, you can make loads of different sort of triangles though I guess most people - me included - go for the equilateral to get even spaces between them. Even if you have to squint it a bit the middle part will fill in nicely.
4 - for some reason putting 4 plants in doesn't look right - the centre doesn't fill in nicely. I tend to go for a diamond/rhombus shape if I have 4 - i.e. an equilateral triangle with one stuck on one of the sides. That can work.
5 - now you are really starting to get into variations now - star, cross, pentagon.
Over and above - you've got more money than I have - apart from bedding flats and plug plants I rarely if ever have 5 or more plants of one variety. They are simply too expensive except for the rich and TV programs. The bedders go into the whiskey barrels or the hanging baskets(out of the reach of the rabbits usually) where we can see them for the one season they live. The plug plants now go into 3" pots to start with. For the first year or so I put the plug straight into the garden (into the outside if they were "rabbit-resistant" or into the stalag if they are rabbit salad.) They rarely survived more than a season or a few weeks - the weeds/mice/slugs and snails got to them. Now all plugs go into cheap 3" pots for a few weeks if not a full year to bulk up and get ready for the vigour of Tipperty.
So because I had these Alicias I had to add a few more to make up the 10 (to get a slight saving on the per plant price - I'm a sucker for that sales ploy. Mentally I know it's marketing but my gut always goes with 'it's a bargain!'). Once the will is broken - i.e. I know that I will buy some plants then I get what I want to buy - all or nothing - I ended up with thirty - 10*3's - all thing sin moderation... including moderation.

Now I only need about a dozen more exotic names and I'll have the inner circle planted up - and an excuse to buy loads more heathers or roses or daffodils or whatever.
