Just received lavender plants!

My order of lavender plants arrived from Richter's Herbs today.  They are tiny.  I kept thinking that I had to prepare a massive area in a side bed for these plants.  Of course they will eventually grow bigger but I really had grandiose plans.  Thank goodness the size of the plants and the amount of my energy (low) combined with a limited window of opportunity to get my neighbor's help will make the job much, much easier.  I was going to move a couple of shrubs and dig out some others (or should I say have someone do it for me), but now I see that one of these bushes is a lovely dark pink azalea and wouldn't that look stunning next to lavender?  Never mind that they require completely different levels of pH.  They will just have to live with the soil as it is!  Luckily I think they are both relatively adaptable plants and the soil there appears to be neither too acid nor too alkaline.  The other bushes are 2 Japanese hollies and a mystery shrub that doesn't flower and just takes up room.(why did a previous owner of this house plant so many Japanese holly bushes in so random of a pattern so close together?).   So out they go.  Or I should say off with their heads.  We plan to cut them down at the soil level and let the roots die off.  Well, that is the theory.  Wish me luck.
