Hopefully experienced posters can help a novice. I am looking to buy a particular type of dwarf lavender plant for a low lavender hedge. Does anyone know where I can source Thumbelina Leigh dwarf lavender plants either in the (North) London area or an online supplier that doesn't charge astronomical delivery rates? I have found an online suppler who wants upwards of £9 delivery...although if this is the norm , I'll have to eat the cost but wanted to try posting for advice first. TIA
