I would caution you to not put multiple forms of Lavander close together. Try not to divide or split up large zones of colour. Keep large undiluted. You could use largish pots and cultivate other forms in them one form per pot, concentrations of colour rather than diffuse impressionistic blurs of colour. always go for strength on strength.
