Their long flowering period of masses of pretty flowers make them worth growing somewhere in your garden.
Hyssop are excellent for attracting bees and other pollinating insects.
They also look best when grown in groups of five or more with other plants of similar size at the back or middle of mixed beds and borders.
A good way to grow them is in groups, again five or more, on their own as a focal point.
Try them as a back drop to informal ponds for a striking display, they look fantastic.
They can be grown with good effect in shrub gardens where their flowers contrast well against the plain shrub foliage.
Some species being fairly tall and with not very pliable stems they may need staking in exposed windy areas.
Many can be grown in containers with great effect, either on their own or with other flowering or foliage plants.
Where: Ideal for mixed flowering borders and beds.
Site: They prefer a position in full sun, they thrive in it!
Hyssop will also do well in partial shade or dappled shade.

Adding well rotted garden compost or any other sort of organic material before planting will help improve the structure and drainage of your soil.
