Perennials for full sun – 10 must-haves for outdoor spaces

Not everyone is fortunate enough to benefit from a nice outdoor space. However, those who have a balcony, a terrace, or a garden facing south, know that this can sometimes become a real headache.

Perennial plants for full sun, maintenance, landscaping, and tips … the pros at Deavita.fr give you all on the subject!

Basic rules for taking better care of your plants in full sun

Although these are full sun plants that don’t mind the heat, you should not take their care lightly. So, before revealing our list of perennials, here is some information to consider to flower a south-facing outdoor space successfully. First, it is important to plant them when the risk of frost is low (April, May). Then, offer them brand new potting soil and containers with drainage holes. To improve the latter, consider putting a layer of clay bile. If you want to plant several perennials in the same planter, they must have the same needs (exposure, watering, fertilizer).

In any case, they produce more effect when grown in groups. To make a tiered garden, combine several staggered flowering perennials. The right order? Place the spring species in the background, the summer ones in the middle, and the autumn ones in the foreground. That way, spring plants will be at their full size in May, while fall plants may only be a few inches tall.

Use geranium potting soil and consider fertilizing from June to August. Using the extended-release fertilizer cones throughout the season is very suitable, as frequent watering in the full sun tends to leave the soil without its valuable minerals. Hoeing and installing an automatic watering system is also a good idea to consider when taking better care of your perennials. Once planted, they will lose their leaves in autumn and regrow in spring, thanks to their strong and robust roots. So, no need to buy it for 4-5 years. Grown in the ground, they limit the proliferation of weeds. The division is necessary, however, when the stumps become too large.

Which full-sun perennials are right for you? Make your choice based on the exhibit and location. Some species are easier to grow than others. Here are 10 to consider for your garden or terrace!

Acanthus is a perennial plant of the Acanthaceae family that grows in dry and rocky places. It has about thirty species of varying heights, six of which are widespread in Europe. Acanthus is a giant, durable and vigorous plant, easy to grow in any rich, deep, and well-drained soil in clumps, borders, or isolated. Moreover, it makes pretty dry or fresh bouquets. Thanks to its pretty imposing foliage and its erect flower spikes, it brings a very graphic and contemporary touch to the garden. Watering side, water copiously until resumption, then water moderately. The soil should stay cool in summer but never waterlogged. At the end of the season, the plant goes dormant, and its leaves turn yellow. It is therefore useless to overwater it.
