The genus Coronilla contains about 20 species of flowering plants in the pea family Fabaceae, native to Europe and North Africa.
They are rocky shrubs with a spreading habit, bearing alternate, green leaves with obovate or oblong leaflets, sometimes bluish-green in glaucous cultivars. The flowers are typical of the family, often of a bright yellow, sometimes white or pink, possibly stained purple.
There are varieties of small size, ideal for pots or planters.

Plant my coronilla
Coronillas will appreciate a dry and well drained ground: they are rocky perennials!
Dip the clumps in a tray filled with water to moisten them well. Plant them when the water is no longer flowing out of the bucket.
Prepare the soil: make holes, leaving a spacing of 20 to 30 cm per foot, and mix the soil with potting soil, sand and peat dust. Place at the bottom of the planting hole an amendment like dried blood or dehydrated horn.
Cover with soil by tamping gently to avoid air around the roots, then water.
Weed my coronilla
In perennial species, weeding also means working your flowerbed – don't let anything develop too quickly to the detriment of others.
Water my coronilla
Water the first weeks after planting, then maybe during the summer period if the weather is dry.
Fertilize my coronilla
With a respectful approach to soil life, it's always better to fertilize a little in advance with organic material that will decompose; spread out a compost that isn't entirely decomposed, with well decomposed manure at the plant's base, and incorporate over 10 cm with a hoe. This operation is carried out in winter so that earthworms and bacteria have enough time to do their job.
Propagate my coronilla
You may divide the plant in autumn.
Choose an older plant, that no longer flowers well, but that still looks healthy enough - don't wait until it's too late !
Dig it up with a pitchfork or a spade - drive the pitchfork into the centre of the clump to divide it in half, in one good cut. Replant the two parts of the plant immediately.
Mulch my coronilla
Mulch the coronillas, it will prevent you from watering and weeding in summer, and - even if they are rather rustic: it will protect the roots of the cold in winter.
Cut down my coronilla
Pruning coronillas is not essential - but it can be beneficial! As a side note, the glaucous varieties do not appreciate too severe a trimming.
If necessary then, in winter, from February to April, before growth begins, cut down the coronillas almost to the foot.
