Sceptic tanks...hmm, a necessary feature but not a pleasant image in a rural home, we've surrounded ours with scented plants.
A low hedge of lavender, white-flowered lilac for the Spring and now, at the height of Summer, lilies. Beautiful potfuls of white, deliciously scented lilies. If the weather was sunnier and warmer the scent would travel on the evening air, but even in this wet weather and less than optimum temperatures the scent is pervasive.
I think that lilies are best in pots. You can then sight them in a prominent position whilst they are in full flower and remove them to a less obvious spot in the garden when they are past their flowering best but need to be fed and watered to build the bulbs for next year.
I have some oriental lilies in a border that I plan to lift in the Autumn and transfer to pots for next year. I think I'll place them on the Party Patio that the Handyman is in the process of constructing...more on that in future posts...for the moment let's enjoy the lilies.
