Prostrate Summercypress: complete guide

Overview

Prostrate Summercypress (Bassia prostrata, also called Forage kochia) is a low, spreading shrublet from the Amaranthaceae family (amaranth and orache family). Native to Central and Eastern Europe through Western and Northern China, it is a true lover of dry conditions.

This plant forms a low, dense mat of fine foliage and is perfect for xeriscaping (water-saving garden design), dry rock gardens and Mediterranean gardens. It is low-maintenance and demands virtually no feeding or intensive management.

Appearance and bloom

Prostrate Summercypress typically grows only 20-40 cm tall but can spread 60-90 cm wide in a low, mat-forming habit. Its fine foliage is light green to grey-green, very decorative and soft to touch.

Flowers are small and inconspicuous, greenish (June-September), but not particularly ornamental. The plant is valued chiefly for its foliage beauty. In autumn, the foliage can take on a reddish-brown or purplish tint, offering additional interest.

Ideal location

Place Bassia prostrata in full sun (minimum 8 hours direct sunlight daily). This plant dislikes shade and will become thin and weak without enough light. It also thrives in warm, exposed locations and at coastal sites where salt and wind tolerance are needed.

The plant is ideal for rock gardens, dry slopes, stony areas and as massing between other drought-tolerant species.

Soil

Bassia prostrata is incredibly tolerant of soil type. It grows in virtually all soil types, from sand to clay, as long as drainage is good. Prefers neutral to slightly alkaline pH (7.0-7.5), but adapts to acidic and alkaline soils alike.

Most important: avoid waterlogging. If you have heavy clay soil, work in sand or gravel. The plant tolerates saline soils well and can even grow in coastal garden conditions.

Watering

Once established (about 2-3 months after planting), water needs are minimal. Water only during extreme drought or very intense sunny spells if leaves show wilting.

During the first season, water regularly (weekly to fortnightly) so the root system establishes well. Let the soil dry out between waterings.

Pruning

Pruning is not strictly necessary. You can cut back excessive growth to maintain shape or balance larger specimens. Remove dead foliage.

At season's end (October-November), you can tidy lightly, but most shrubs need no pruning at all.

Maintenance calendar

March: Check for winter damage. April-May: Regular watering in early growth, no feeding. June-September: Flowering, minimal care. October-November: Growth slows, reduce water drastically. December-February: Winter dormancy, minimal care.

Winter hardiness

Bassia prostrata is hardy in USDA zones 5-10 (to roughly -18 degrees Celsius). In very cold zones (4 and colder), the plant may experience frost damage, but usually recovers in spring.

In zone 4, mulch the plant in December for extra protection. In warmer zones (9-10), it grows year-round.

Companion plants

Bassia prostrata combines beautifully with other drought-tolerant plants: lavender, Santolina, sedums, Verbascum, Achillea and Echinops. It also works well nestled between stones in rock gardens.

Grouping works well: place 3-5 specimens in dense clusters for strong visual impact.

Closing

Prostrate Summercypress is a reliable, low-maintenance choice for dry, sunny locations. With minimal care, it behaves like a silent perfectionist in your garden.
