There are a lot of perennials blooming in summer. These are, for example, the ones with yellow flowers: meadowsweet and common yarrow, Missouri and shrub primrose and whorl.The Russells, a very original and not very popular perennial in Poland (grows up to 150 cm), also has bright yellow flowers.
During the flowering period, the tritome clusters look exotic.Its dense, slender spikes, mostly composed of bicolor yellow and orange flowers, appear from June to October.Tritomes grow up to 130 cm.They withstand drought well, require fertile and humus soils. They are also suitable, as are the silk mullein, for gravel gardens.
Similar places like ash-leaf and red groyne.The first is a long-lived perennial with erect, stiff stems 80-100 centimeters high, the second, 70 centimeters high, belongs to short-lived perennials.
Plants of both species have pink, pink-red (in macula) and white flowers, and bloom in June and July or longer if faded inflorescences are removed from them.Faassen's catnip can be planted next to the groyne because of its lavender-blue flowers contrasting nicely with it.
Dry soil is also liked by garden mulch, low evergreen shrub (15-25 centimeters), gypsophila 'Rosea' - a low perennial and a double-necked valerian that forms convex clumps of 30 cm high.These perennials are especially effective during flowering, i.e. from May to July.
The sun is also liked by thyme and various sedum.It is also worth planting a woolly purgatory in dry stands because of its soft silvery leaves.
