Without being demanding, some plants flower more when they benefit from copious waterings. This is the case with ‘Diamond Frost’ spurge and loosestrife.
Euphorbia: regular watering
The ‘ diamond frost’ euphorbia is planted in the sun, in a pot or in the ground. It likes heat, but fears drought.
Water this euphorbia every two days, adding fertilizer every week so that it remains filled with a multitude of small white flowers similar to snowflakes.
Lysimachus: moisture without excess
A not very hardy perennial grown as an annual, loosestrife congestifolia is often used as a ground cover or suspended in a sunny situation. Its bright yellow flowers gathered in an umbel follow one another in summer and autumn. Be careful, this loosestrife likes cool to moist soils, but never soggy!
