‘Lavender needs full sun, well-drained soil and little water when established. Hosta thrives in part to full shade and moisture,’ explains Morris Hankinson of Hopes Grove Nurseries patiently.
Morris Hankinson is the founder and managing director of Hopes Grove Nurseries Ltd, the UK’s solely specialist grower-retailer of hedging crops. He established the thriving enterprise in 1992, shortly after graduating with a Commercial Horticulture Degree from Writtle College, Essex.
‘Their requirements are so different that it will become a battle to keep them both thriving because the lavender will dry out the soil for the hosta, and providing the hosta with enough water will lead to root rot for the lavender.’
Pick one, then. Or, on the very least, plant them as far-off from one another as potential.

Next on our record of perennials it’s best to by no means plant collectively are heuchera (or coral bells, for those who choose) and anemone bulbs.
‘Heuchera have shallow roots and grow low to the ground. They need some space to fully thrive and show off the stunning foliage colours. They will soon fade away if covered by a bigger plant, such as Japanese anemones,’ factors out Morris.
‘These have dense mats of spreading roots and will soon overwhelm heucheras with their need for nutrients, moisture and space.’
Instead, attempt planting one thing like salvia along with your coral bells (they’re nice companion crops) and early spring bulbs, like tulips and daffodils, alongside your anemones. It makes for a far happier atmosphere, we promise.
3. Irises and daylilies

‘These both have thick roots that will compete for space, moisture and nutrients, which can limit flowering on one or both,’ says Morris. ‘Also, depending on the soil they are growing in, the root mess that will entail can cause waterlogging and eventually root rot, especially in heavy clay soil.’
Spread them out throughout your backyard, then, or attempt planting them in separate pots. Easy.
4. Peonies and delphiniums

‘Peonies enjoy full sun and can struggle if overcrowded. Delphiniums grow tall and will shade peonies along with other lower-growing plants,’ he explains. ‘They also need a lot of water and nutrients, which will compete with the shallow peonies’ roots. This could result in fewer or smaller peony flowers.’
When you think about the truth that we develop peonies for his or her showy, fluffy blooms, that’s no small factor. Keep these two aside in any respect prices!
