    Early Summer Gravel Garden Plants We give you the tools, you create the garden © GARDENCOURSES.COM 2021 Crambe maritima This is a plant which very much evokes the seaside. Its ground- hugging, glaucous crown of leaves hunker down low and in early summer it produces small sweet-scented flowers reminiscent of Alyssum. As its common name sea kale suggests, the leaves of this plant are edible. Crambe maritima does a good job as a compact filler plant, such as Alchemilla mollis might in a border. If you’re looking for a dramatic statement plant, check out its relative Crambe cordifolia. We give you the tools, you create the garden © GARDENCOURSES.COM 2021 Corokia cotoneaster ‘Ohau Yellow’ Instantly transport yourself to the Outback with a Corokia cotoneaster! This variety “Ohau Yellow’ was spotted in full flower at Kew Gardens and can be tricky to source, but there are many varieites to choose from, all sporting an intricate network of geometrically spectacular stems giving rise to the plants common name; Wire Netting bush. Place this plant where you will pass right by it. The stems are best marvelled at close up. We give you the tools, you create the garden © GARDENCOURSES.COM 2021 Self sowers Self sowing plants like this Nigella damascena ‘Miss Jekyll Alba’ will be quite happy in a dry garden and will seed themselves around gently wherever they’re happy. Beware some other drought tolerant plants that will survive in a dry spot but may be too enthusiastic with their propagation, such as Verbena bonariensis.

We headed north through the hills that fringe the Algarve. Here the traffic declined and we enjoyed a winding scenic transfer through these little-visited hills. The roadsides held an abundant and diverse range of flowers for the sharp-eyed to pick out. We stopped at a scenic viewpoint Mirador on a hilltop at the halfway point, to stretch our legs and take in a little of the botanical riches to be discovered. Birdlife was unfortunately rather thin for those interested, but the trip ahead would more than make up for it. The most notable plant found were a number of examples of Ornithogalum broteroi: a species confined to Iberia. Having spent rather too long ‘stretching our legs’, we headed on to complete our transfer to Mertola a little later than planned, where we were soon assigned our rooms and arrangements made to meet up later for our evening meal in town. Day 2 Wednesday 18th April Our day today was fully spent within the Castro Verde SPA, looking for the specialised and threatened steppe birds for which the area is renowned.

Friday 24th February Malaga to Benaojan We had a snack in a small cafe at the airport before heading for our hotel. The palm trees looked stunning in the bright clear blue sunny skies as we headed out of Malaga, through Torremolinos, past Marbella and up the beautiful scenic route of the very twisty A397 to Ronda. Several kestrels and goldfinches were seen from the car. There were many almond trees to be seen, the sun caught the pink petal just right, making them a lovely spectacle. As we left the main road, we saw our first blue Iris planifolia. We dropped down the valley to our hotel the Molino del Santo at Benaojan. Saturday 25th February Benaojan, Montejaque, and Zahara Our first stop was by the small chapel on the rocky outcrop by the road above our hotel. Here we had a good look at Narcissus assoanus. We could look down into the valley where the gentle bells of the goats and sheep carried up to us. There were a couple of clouded yellows flitting about in the warm afternoon sun. Further up the hill we drove through Montejaque with its almond trees in full, pink bloom, to a flat area between the rocky limestone hills ‘Penon de Mures’ and ‘Cerro Tavizna’. A rocky knoll beside the road had our first Narcissus papyraceus, with its heady hawthorn-like scent and pure ‘paper-white’ blooms.

Horticulture Research (2020) 7:107 Horticulture Research https://doi.org/10.1038/s41438-020-0332-2 www.nature.com/hortres REVIEW ARTICLE Open Access Germplasm resources and genetic breeding of Paeonia: a systematic review Yong Yang1,2,3,4,MiaoSun1,2,3,4, Shanshan Li1,5, Qihang Chen2,3,4, Jaime A. Teixeira da Silva6, Ajing Wang1,5, Xiaonan Yu2,3,4 andLiangshengWang1,5 Abstract Members of the genus Paeonia, which consists of globally renowned ornamentals and traditional medicinal plants with a rich history spanning over 1500 years, are widely distributed throughout the Northern Hemisphere. Since 1900, over 2200 new horticultural Paeonia cultivars have been created by the discovery and breeding of wild species. However, information pertaining to Paeonia breeding is considerably fragmented, with fundamental gaps in knowledge, creating a bottleneck in effective breeding strategies. This review systematically introduces Paeonia germplasm resources, including wild species and cultivars, summarizes the breeding strategy and results of each Paeonia cultivar group, and focuses on recent progress in the isolation and functional characterization of structural and regulatory genes related to important horticultural traits. Perspectives pertaining to the resource protection and utilization, breeding and industrialization of Paeonia in the future are also briefly discussed.

    Peony Species Harvey Buchite-Hidden Springs Flower Farm Spring Grove, Minnesota

    Peony Species Harvey Buchite-Hidden Springs Flower Farm Spring Grove, Minnesota Peony Species are the wild ancestors of our garden peonies. How many peony species are there? In 2010 Hong De-Yuan published Peonies of the World Taxonomy and Phytogeography, a scholarly, well-researched peony monograph focused on peony taxonomy and peony habitats. He followed this with the publication of Peonies of the World, Polymorphism and Diversity in 2011. Hong lists 33 species with 15 subspecies, for a total of 48. Gardeners and horticulturists are often more interested in selected forms of species than taxonomists so that they may be surprised at the classification. Where are peonies native to? Wild peonies are only found in the temperate northern hemisphere, USDA Plant Hardiness Zones three to eight. The majority are found in Asia westward across to far western Europe. Two peony species are native to the North American Continent and are not known to be successful in cultivation. There are three sections or main divisions of the species in genus Paeonia. Section Onaepia is represented by two species native to North- ern Mexico and the Western United States. They are found on dry mountain chaparral with an extended dry period and relatively short growing season. Surprisingly their closest relatives by DNA testing are the woody peonies! Paeonia brownii and Paeonia californica are both diploids and both are extremely difficult to grow. Paeonia brownii has a wider distribution and has one to four flowers per stem. It grows at 2,000-6,000 feet on rocky granite or volcanic soils from Northern California, Idaho, Nevada, Oregon, Utah, Washington and Wyoming.
